What to Do if Your Howard, OH Home’s Hot Water Stopped Working

By Cosby HVAC Blogs

Waking up to a cold shower on a brisk morning is an unwelcome surprise, yet it’s a scenario far too many homeowners face when their home’s hot water stopped working. This abrupt plunge from comfort to inconvenience isn’t just about missing your morning routine. It’s a clear signal that something’s gone awry in your home’s sanctuary.

As you stand there, shivering, questions begin to swirl. What caused this? Is it a simple fix or a sign of a bigger issue lurking within your home’s essential systems?

The importance of resolving this cannot be overstated. Access to hot water is a pillar of modern living, affecting everything from your daily comfort to household chores. Recognizing the urgency to restore warmth and normalcy, this article offers a lifeline, guiding you through diagnosing the problem and illuminating when it’s time to seek professional help. Let’s unravel the mystery of your hot water woes and set you on the path to a solution.

How Does Your Hot Water System Work?

When it comes to maintaining a comfortable home, understanding your hot water system is crucial. There are mainly three types of water heaters found in homes: traditional tank water heaters, tankless water heaters, and those powered by gas or an electrical system. Each type operates differently and comes with its own set of guidelines for troubleshooting and maintenance.

Tank water heaters store and heat water in a large tank to ensure that hot water is available when you need it. These are common and can be powered by gas heating or an electrical system.

A tankless water heater, on the other hand, heats water directly without the use of a storage tank. When you turn a hot water tap on, cold water travels through a pipe into the unit. It is then heated by either a gas burner or an electric element to provide a constant supply of hot water.

Knowing the type of water heater you have is the first step in diagnosing any issues. For instance, a gas water heater uses a pilot light, which can be a source of problems if it goes out, while an electric water heater relies on its electrical system to function properly.

Common Causes of Hot Water Issues

A lack of hot water in your home can stem from several common issues, depending on the type of water heater you have.

For gas water heaters, one of the most frequent problems is with the pilot light. If the pilot light goes out, the gas won’t ignite, and your water won’t heat up. This can be due to a faulty pilot light, a problem with the gas supply, or issues with the heater’s thermostat.

Electric water heaters, on the other hand, might face heating element failures. These elements are responsible for heating the water, and if they burn out or malfunction, you’ll find yourself facing a cold shower.

Similarly, the heater thermostat plays a critical role in regulating the temperature of the water. If it fails, it can result in water that’s too hot, too cold, or completely unheated.

Another common culprit across both types of systems is sediment buildup. Over time, minerals from the water can accumulate at the bottom of the tank and insulate the water from the heater’s source of heat. This not only affects the efficiency of your water heater but can also reduce its lifespan.

Initial Troubleshooting Steps When Hot Water Stopped Working

When your home suddenly finds itself without hot water, a few initial steps can help identify or even solve the problem. For electric water heater owners, checking the power supply is a good start. Sometimes, the solution is as simple as flipping a tripped circuit breaker back on.

Similarly, for those with gas heaters, ensuring the gas supply hasn’t been accidentally turned off can be a quick fix. This is something homeowners in Ohio have encountered, especially during colder months when systems are under more strain.

Adjusting the thermostat on your water heater might also resolve the issue. It’s not uncommon for settings to be changed accidentally, leading to water that’s colder or hotter than desired.

Another effective hot water heater troubleshooting step involves flushing the tank to remove sediment buildup. Over time, sediment can accumulate and hinder your water heater’s efficiency. Flushing the tank can restore function and improve heating efficiency.

When to Call the Professionals

There comes a point in hot water heater troubleshooting when the problem extends beyond a simple DIY fix. If your water heater exhibits complex issues, like leaks or noises that you can’t easily diagnose, it’s time to call in the professionals.

This is particularly true for emergency water heater repairs that involve gas lines or electrical components, where the risk of injury or further damage to your home is high.

Professional HVAC technicians have the tools and knowledge necessary to safely and effectively address these problems. They can perform water heater replacement or repair services that not only fix the issue at hand but also ensure your system operates efficiently in the long run.

For residents of Howard, OH, finding a trusted professional can mean the difference between a quick fix and ongoing problems.

In cases where your water heater is old or the repair costs are high, a technician might recommend a water heater replacement. This can be a more cost-effective solution over time, offering improved energy efficiency and reliability.

Whether it’s an unexpected failure or the result of years of wear and tear, professional guidance can help you navigate these decisions with confidence and ensure your home’s comfort is restored as quickly and safely as possible.

Regain Comfort with Expert Care

After navigating through the steps to troubleshoot why your hot water stopped working, it’s clear that sometimes, the solution requires more than a quick fix. This is where Cosby Heating & Cooling steps in.

emergency boiler repair

Emergency Boiler Repair: What to Do When Your Heating Fails in Bellville, OH

By Cosby HVAC Blogs

When the temperature drops and your home heater suddenly stops working, it’s usually cause for panic. The thought of shivering through the night or enduring cold showers is enough to send anyone into a frenzy. 

But fret not! Emergency boiler repair services in Bellville, OH are here to save the day. In this article, we’ll discuss common reasons for heating system failures, signs that your boiler is not working properly, and what to do when your boiler breaks down.

By understanding the dangers of gas leaks, as well as how to choose a reliable boiler repair company, you’ll be well-prepared for any emergency that comes your way!

Common Reasons for Heating System Failures

There are several common reasons why your heating system may fail. Here are a few of them:

Malfunctioning Thermostat

One of the most frequent culprits is a faulty thermostat. If your thermostat is not functioning right, it can stop your boiler from turning on or off at the appropriate times.

Faulty Fuel Supply

Another common issue is a lack of fuel or a faulty fuel supply. Make sure to check that your fuel source is not depleted and that there are no blockages in the fuel line.

Clogged Filter

A clogged filter can restrict airflow and cause your boiler to overheat or shut down. Regularly changing or cleaning your filters can help prevent this problem.

Electrical Issues

Other potential causes of heating system failures include electrical issues, such as a blown fuse or tripped circuit breaker. It could also be caused by mechanical problems, like a broken pump or motor.


In some cases, the boiler itself may be old. If this is the case, you may have to replace it or get repairs done.

Understanding these common reasons for heating system failures can help you troubleshoot the issue and determine whether you need to call for emergency boiler repair in Bellville.

Signs That Your Boiler Is Not Working Properly

Recognizing the signs of a faulty boiler is essential in preventing further damage and ensuring the safety of your home. These are signs to watch out for:

No Heat or Hot Water

A common sign is a lack of heat or hot water. If you notice that your home is not heating up or your showers are cold despite the boiler being on, it is a clear indication that something is wrong.


Strange noises coming from your boiler, such as banging or whistling sounds, can also be a sign of an underlying issue. In this situation, you can call your landlord to verify that the noises aren’t caused by something else. If it’s your heating system, call a boiler repair company.

The Smell of Gas

If you smell gas or notice a sulfur-like odor, it’s imperative to act quickly, as this could indicate a gas leak. Other warning signs of a faulty boiler include fluctuating water pressure, frequent boiler cycling, or a pilot light that keeps going out.

What to Do When Your Boiler Breaks Down

In the unfortunate event that your boiler breaks down, there are a few basic steps you can take to address the issue before calling for emergency boiler repair in Bellville.

First, check if the pilot light is on. If it has gone out, carefully follow the manufacturer’s instructions to relight it. However, if you smell gas or suspect a gas leak, do not attempt to relight the pilot light and immediately evacuate your home.

Next, check the thermostat to ensure it’s set to the desired temperature and functioning correctly. Sometimes, a simple adjustment or battery replacement can solve the problem.

If these initial checks do not resolve the issue, it’s time to call a professional boiler repair company in Bellville.

The Dangers of Gas Leaks 

Gas leaks and pilot light issues are serious concerns when it comes to boiler malfunctions. They can lead to carbon monoxide poisoning, which is a silent and potentially deadly threat. If you smell gas or suspect a leak, do not hesitate to evacuate your home and immediately call your local gas company or emergency services.

Again, it’s imperative to never attempt to fix a gas leak yourself, as this should only be done by trained professionals. Also, if your pilot light keeps going out, it could be a sign of a faulty thermocouple or other underlying issues. Ignoring these problems can lead to fires, leaks, or even explosions.

Always prioritize your safety and seek expert help for any gas-related boiler issue.

Choosing a Boiler Repair Company in Bellville, OH

When it comes to emergency boiler repairs, choosing a reliable, experienced boiler repair company is essential. This is how to find one:


Begin by researching local companies and reading reviews from previous customers. Look for a company that specializes in boiler repair and has a good track record for quality service.

Check for Licenses and Insurance

Always verify that the company is licensed, insured, and certified to handle boiler repairs. Without this information, you won’t know if the business is legitimate.

Get a Clear Estimate

A trustworthy boiler repair company will provide you with a clear estimate of the repair costs and explain the necessary repairs in detail. They should also offer emergency services and be available 24/7, as boiler breakdowns can happen at any time.

By selecting a reputable company in Bellville, you can have peace of mind knowing that your emergency boiler repair is in capable hands.

geothermal heat pump installation

Geothermal Heat Pump Installation in Mt. Vernon, OH: 3 Things to Know

By Cosby HVAC Blogs

Are you tired of skyrocketing energy bills and unreliable heating systems during Ohio’s unpredictable winters? The solution might be right beneath your feet. Geothermal heat pump installation harnesses the Earth’s consistent underground temperatures and offers an efficient and sustainable alternative to traditional heating methods.

Imagine a winter where your home remains comfortably warm without the hefty energy costs. This isn’t a distant future technology. It’s a practical solution available right now in Mt. Vernon, OH.

Geothermal heating not only promises significant savings on your energy bills but also aligns with an eco-friendly lifestyle. Read on to explore how this innovative technology can transform your home heating experience and contribute to a greener future.

1. Significant Reduction in Energy Bills

Unlike traditional heating systems that burn fuel or use large amounts of electricity, a geothermal heat pump taps into the stable temperatures underground. This method is not only environmentally friendly but also incredibly efficient.

The science behind this efficiency is straightforward. Below the frost line, the Earth maintains a consistent temperature, ranging around 50-60°F year-round.

Geothermal systems leverage this natural heat reservoir in winter to warm your home. In the summer, they do the reverse by extracting heat from your home and transferring it back into the ground. This process reduces the need for excessive electrical heating or cooling, often the culprit behind high energy bills.

The real-world impact of this technology is substantial. Homeowners who have switched to geothermal heating report savings of up to 70% on their heating and up to 50% on cooling their homes compared to traditional HVAC systems.

For instance, a study by the Federal Energy Management Program found that geothermal systems offer one of the lowest lifecycle costs of all heating and cooling systems. This includes the initial installation cost spread over the system’s lifespan, as well as ongoing energy costs.

While the upfront cost of a geothermal system can be higher than traditional systems, the long-term savings are undeniable. In Ohio, where weather patterns can be unpredictable and harsh, the efficiency of a geothermal heat pump ensures that you’re not only saving money but also enjoying consistent and comfortable temperatures in your home.

With the added benefit of available tax credits and incentives for renewable energy solutions, the financial aspect becomes even more attractive.

2. Long-Term Cost-Effectiveness and Incentives

When you think about installing a geothermal heat pump in your Mt. Vernon home, consider it an investment for the future. While the initial cost might seem higher than traditional heating systems, the long-term savings and incentives make it a financially wise choice.

Initially, setting up a geothermal heating system involves installing an underground loop system. This process can be more expensive upfront compared to a conventional HVAC system. However, the key to understanding its value lies in looking at the long-term picture.

Over time, the energy savings from a geothermal system can offset the initial installation costs. For example, homeowners typically see a reduction in their heating and cooling costs by about 50-60%. This means that over a period of 5 to 10 years, the savings accrued can cover the initial investment.

To encourage the adoption of renewable energy sources, the government offers various incentives for geothermal heat pump installations. One significant benefit is the federal tax credit, which can cover a portion of the installation cost.

These incentives not only make geothermal systems more affordable but also shorten the payback period. As a homeowner, you not only reduce your carbon footprint but also gain financial rewards for choosing a sustainable option.

Geothermal systems are known for their durability and require less maintenance compared to traditional HVAC systems. The underground loop system has a lifespan of about 50 years, while the indoor components can last for around 25 years. This longevity means fewer repairs and replacements, adding to the overall cost-effectiveness of the system.

3. Eco-Friendly and Sustainable Operation

In today’s world, where environmental concerns are more pressing than ever, geothermal heat pump installation stands out as a forward-thinking choice. This technology is not just about heating and cooling your home efficiently. It’s about making a positive impact on our planet.

Geothermal heat pumps operate using the Earth’s natural heat, which is a renewable resource. This means they don’t burn fossil fuels or release harmful emissions into the atmosphere.

In contrast to conventional heating systems, which often rely on gas, oil, or coal, geothermal systems offer a cleaner, more sustainable way to keep your home comfortable.

A significant advantage of these systems is their minimal ecological footprint. Geothermal heat pumps have a closed-loop system that circulates water or a water-antifreeze mixture underground, absorbing or releasing heat to the ground. This process is incredibly eco-friendly, as it doesn’t deplete natural resources or contribute to air pollution.

One of the most impactful benefits of geothermal heating is the reduction in carbon emissions. Traditional HVAC systems can emit significant amounts of carbon dioxide, a leading greenhouse gas. Geothermal systems, however, have a much lower carbon footprint. 

Moreover, because these systems are highly efficient, they require less energy to operate. This reduced energy consumption is vital in the global effort to curb electricity usage and its associated environmental impacts. As an HVAC company committed to eco-friendly solutions, we understand the importance of offering technologies that help our clients reduce their environmental impact.

Choosing a geothermal system is a step toward a more sustainable lifestyle. It’s a practical solution that aligns with the growing global emphasis on conservation and environmental responsibility.

The Ultimate Guide to Choosing the Right Furnace for Your Fredericktown, OH Home

By Cosby HVAC Blogs

Ohio can experience some extremely cold temperatures in the winter months, so you want to ensure you and your family can stay warm. A furnace is the perfect solution, but you need to find the right one.

There are several different types, and each has its own benefits and drawbacks. Understanding each type will help you make the best choice based on your needs. 

In this guide, we’ll go over the different types of furnaces to give you an idea of how they work. We’ll also cover some other important factors that could affect your decision. Keep reading for more.

Types of Furnaces

Furnaces can vary significantly, but the fuel source is the biggest difference that you need to think about. Some may simply not be viable for you which could help you narrow things down a bit. You should consider all of the options available to you so you can determine what would work best.

Natural Gas

Natural gas furnaces are the most popular type throughout the US. With that in mind, a gas furnace needs to be connected to a municipal gas line to work. As such, they may not be viable in some situations.

Gas furnaces tend to have a higher installation cost than other types, but that doesn’t mean they’re the most expensive overall. They’re a relatively energy-efficient furnace type with lower operational costs. In the long run, they can end up costing less than other types of furnaces.

One potential drawback is a safety risk that isn’t present with other furnaces. These run on CO2 and could leak if there’s a malfunction.

CO2 is odorless and colorless, making it impossible to detect without a CO2 alarm. It’s very harmful, and can potentially be fatal. If you opt for a gas furnace, make sure you keep a CO2 alarm close to it in case it leaks at all.


Electric furnaces are another popular option, and they tend to be a bit less expensive to install than gas furnaces. The operation is fairly similar, so swapping from one to the other shouldn’t cause you any issues.

The main benefit of going for an electric furnace is that they’re easy to fuel. All you need is an electricity supply, so you don’t need to connect it to a gas line and there’s no need to keep restocking in fuel. 


The overall operation of a propane furnace is similar to a gas or electric furnace. The key difference is that these aren’t connected to a constant fuel supply. 

Instead, they use propane canisters. On the downside, you need to remember to replace these so you don’t end up running out. It’s a good idea to keep some stored away so you can swap the old one out for a new one as soon as it’s empty. 

The benefit of this is that they’re more versatile, and can be placed almost anywhere. This makes them a popular choice for cabins and camper vans. They work similarly to the two above but don’t need to be connected to a continuous fuel source.

Installation is generally quite cheap compared to gas furnaces. They are, however, less efficient. In the long run, they can work out to be a more expensive solution.


Oil furnaces are less expensive to install, but they’re still generally less popular than other types. Bear in mind that they’re also somewhat inefficient, which is a crucial factor for a lot of people.

They tend to require more maintenance than other furnaces. This can result in higher costs in the long term.

When they’re kept in good shape, however, oil furnaces can last for decades. You won’t need to worry about replacing one any time soon which can balance the cost and prevent a lot of hassle. 

One key thing to remember is that you need to ensure the oil tank is ready. The furnace may dry up if the tank is empty, and this can cause damage to the system.


Despite being arguably the most traditional type of furnace, these are fairly uncommon. They’re fairly cheap to install, but they’re also the least efficient option available.

People tend to avoid wood furnaces as they take more work than other types. You need to have wood stored so you don’t run out. You also need to consistently add more to the furnace to keep it going.

It’s worth noting that there are some models available that use wood as the primary fuel source and another type as a backup. This can be a good choice, but many people prefer a furnace with a different primary fuel source.

Other Factors to Consider Before Installing a Furnace

The fuel type may be the main thing you think about for your new heating solution, but it’s not the only differentiator. There are several other factors that you can consider to help you find the perfect furnace for your home.


Set an initial budget so you know what your price limit is. This is generally the first thing you should think about, as it may determine what your options are.

Don’t forget to also think about operating and maintenance costs. While one type of furnace may be a cheap option now, it could cost you more in the long term.

Furnace Size

You want to get a furnace that’s a suitable size for your home. If it’s too small or too large, it may be inefficient and won’t heat your home as it should.

A professional HVAC company such as Cosby Heating & Cooling can help with this. By assessing your home we can recommend the most suitable options for maximum efficiency.

Additional Features

You may want to take advantage of modern features such as multi-stage operation and variable speed blowers. While these offer additional benefits, they can also increase the price, so discuss these with our team before you buy a furnace.

Your New Furnace

With so many types of furnaces, it can be difficult to know what the right choice is. Cosby Heating & Cooling offers furnace installation and various other heating and cooling services in Fredericktown, OH.

DIY HVAC Maintenance Tips for Fall in Howard, OH

By Cosby HVAC Blogs

Are you ready to take control of your home’s comfort this fall? In Howard, OH, and other places in Knox County, the leaves are already changing. You’re likely also feeling a chill in the air most mornings.

It’s time to gear up for the coziest season of the year. This means taking care of HVAC maintenance.

We’ll show you how to tackle DIY HVAC maintenance like a pro. With these simple steps, you’ll keep your heating system running efficiently, ensure your family’s comfort, and save money on energy bills.

Say goodbye to chilly nights and hello to a toasty, welcoming home. 

Start the Fall Season with Clean Filters

When the season shifts, it’s time to change the air filter. These filters play a crucial role in maintaining your system’s efficiency and your indoor air quality.

Over time, dust, debris, and allergens clog air filters. Nothing unusual as the primary role of an air filter is to trap what you don’t want circulating in your indoor air. This buildup can restrict airflow, making your HVAC system work harder to heat your home. 

Clogged filters can impact indoor air quality by recirculating pollutants and allergens throughout your home. This can create concerns for household members with allergies or respiratory issues.

Changing the air filter is a simple yet essential, step in preparing your HVAC system for the fall season.

Any home improvement store in Mt. Vernon, Howard, or the surrounding cities carries filters, but your local HVAC company includes a filter change when they perform routine maintenance.

Unblock Air Vents and Registers

You’ve taken care of that dirty, clogged air filter, but don’t overlook the vents and registers. They are the gateways for warm air from the furnace to flow into your living spaces.

It’s not uncommon for air vents and registers to become unwitting victims of household clutter.

Furniture, rugs, and other items placed over vents and registers hinder airflow. The result is uneven heating. Some areas of your home will feel too warm, while others will stay chilly.

Like dirty air filters, clogged vents, and registers can force your HVAC system to work harder.  Not only can it lead to higher energy bills, but it can cause wear and tear on the system.

Check for Leaks in Your Ductwork

Another easy DIY HVAC maintenance task can help you save money on energy bills and prevent overworking your furnace. Check for leaks and gaps in your ductwork.

Your ductwork is one of the most overlooked components of your HVAC system. Ductwork transports conditioned air from the furnace to the supply vents.

Ducts can develop tiny leaks, which may seem inconsequential but can significantly impact the efficiency of your HVAC system. Sometimes ductwork loosens and allows air to escape through the gaps.

Give your ductwork a thorough inspection this fall. Look for visible gaps, cracks, or loose connections. If you find any, don’t worry; it’s a manageable problem.

Seal leaks with either duct tape or mastic, a gooey adhesive that closes gaps and keeps your warm air where it belongs. If you have aging ductwork in your Howard or Mt. Vernon, OH, home, this might be the year to consider an upgrade.

Give the Thermostat a Little TLC

The thermostat is control central to your HVAC system. If it’s not working properly, your furnace may not even turn on, much less heat your home.

Thermostat care is so easy even the least experienced DIYer can handle the job.

First, clean the thermostat. Carefully remove the thermostat cover and use a soft paintbrush to gently clean the internal components. Make sure no dirt or debris obstructs the thermostat’s sensors.

Next, calibrate the thermostat. If the thermostat loses calibration, it won’t give accurate temperature readings. Consult your thermostat’s user manual for instructions on how to recalibrate.

Test for functionality now. Set the thermostat to “Heat” and raise the temperature a few degrees above the current room temperature. Listen for a click (it means the thermostat is engaged) and let the system run for a while to confirm you have warm air circulating.

Set the thermostat back to its original temperature. Listen for a click to indicate the system has turned off.

If you haven’t already done so, consider upgrading to a programmable thermostat. A smart thermostat can revolutionize the way you manage your HVAC system. It’s an excellent home improvement upgrade that most homeowners can do themselves.

Test Carbon Monoxide Detectors

During the colder months, the risk of carbon monoxide (CO) exposure increases. Fuel-burning appliances like furnaces can produce high levels of CO. Testing your carbon monoxide detectors in the fall is critical to protecting you and your family.

Here’s what you should do:

  • Replace batteries
  • Test functionality
  • Verify correct placement
  • Check end dates
  • Understand the alarms

Most models have a test button. When pressed, the alarm sounds to confirm the detector is working correctly.

You should install CO detectors near sleeping areas and on every level of your house. Pay attention to manufacturer guidelines about proper installation height and distance from potential CO sources.

If you need to replace CO detectors or have questions about how to maintain them, a local HVAC company in Knox County, OH can assist.

DIY HVAC Maintenance vs the Professionals

While most homeowners can manage DIY HVAC maintenance tasks, there’s no substitute for the expertise of a professional HVAC maintenance service in Howard, OH.

HVAC professionals scrutinize every detail of your heating system. During a maintenance visit, they identify potential issues before they become major problems. This includes examining components like the heat exchanger, burners, electrical connections, and the thermostat.

You should have an HVAC tune-up each year before colder weather arrives. Routine maintenance not only helps you prepare your HVAC for winter, but it also helps prevent an unexpected and costly furnace repair.

Mt Vernon, OH Fall HVAC Upgrades: What’s Worth Investing In

By Cosby HVAC Blogs

Fall has arrived, and with it comes fluctuating temperatures ranging from a crisp 40 degrees at night to a toasty eighty degrees during the day. It’s the perfect time to show your HVAC system some extra love so it can keep up with the temperature changes.

By investing in fall HVAC upgrades, you can make a world of difference in keeping your home cozy and impressively efficient. Lower energy bills and peace of mind also come along with these upgrades.

So what are the best HVAC upgrades to consider this fall? Here are a few of our favorite ones.

Top Fall HVAC Upgrades

HVAC systems last for about fifteen to twenty-five years. If your system is older than this, investing in a new, energy-efficient unit can keep you cool during those warm Ohio afternoons. Consider options like geothermal systems, heat pumps, or energy-star-rated AC units.

If your system is only a few years old, it might benefit from the following upgrades before winter.

Repairing Ductwork

If you’ve been dealing with skyrocketing energy bills lately, there may be a gap in your ductwork. 

Also, when your ducts aren’t running smoothly, it can lead to improper airflow throughout your home. As a result, your air can end up being warmer than it should be. This causes your HVAC system to work overtime to keep you comfortable.

Bad ductwork can also contribute to higher dust levels in your home. When air can’t flow through the ducts, dust tends to build up.

Reach out to your local HVAC contractor to assess the state of your ducts and recommend the best solutions for your home. Fixing your ducts can improve the efficiency of your HVAC system by up to twenty percent.

Upgrading to a Smart Thermostat

Smart thermostats automatically adjust the temperature of your home based on occupancy, time of day, and weather. You can also control them remotely using an app, so it’s easy to make changes when you’re not at home.

For those who want to save money on their electric bill, energy-saving options are available too.

HEPA Filters

If you’re looking to improve air quality in your home, upgrading your HVAC system with HEPA filters is a great solution. These filters remove itty-bitty particles as tiny as three-tenths of a micron. So pesky dust, irritating pollen, clingy pet dander, and even some viruses will be removed from the air before they circulate through your home.

It can make a real difference for folks who suffer from allergies and asthma. Because the fine mesh in these filters traps all those yucky allergens, it helps to reduce those uncomfortable symptoms like sneezing and coughing.

HVAC Zoning

With HVAC zoning, different areas of the home can be set to specific temperature levels. This gives the occupants greater flexibility in managing the heat.

Since people are bound to have different temperature preferences, zoning can save energy by ensuring other rooms aren’t cooled more than necessary.

New Insulation

Insulation helps HVAC systems work more efficiently by reducing energy waste and heat transfer. By keeping your home better insulated, you can reduce the amount of power needed to cool your home, leading to lower energy bills.

Plus, insulation reduces noise transmission between rooms, giving you a more peaceful living environment.

Benefits of Upgrading Your HVAC System

Breathing in clean air is essential during those chillier months when you spend more time indoors. Upgrading your HVAC system helps filter out allergens, dust, and other airborne particles so you can breathe easy.

Moreover, neglecting upgrade options can lead to costly repairs down the road. By investing in furnace maintenance, you’re taking proactive steps to avoid breakdowns.

When to Seek an HVAC Company

Some upgrades are more urgent than others. For instance, if you notice your home feels muggy or damp, it could be a sign that your HVAC system isn’t properly controlling the humidity. This can be caused by a variety of factors, including:

  • A malfunctioning AC unit

  • Improper ventilation

  • Leaky ductwork

A qualified HVAC technician can assess the situation and provide recommendations to address the issue.

If you notice a drop in comfort or an increase in your energy bill, that’s also a sign that your HVAC system isn’t operating at top efficiency. Other problems that require immediate attention include:

Strange Noises

It’s not uncommon to hear a gentle hum coming from your HVAC system. That soft humming noise is a telltale sign that everything is running as it should be.

Similarly, hearing clicking sounds when your system starts up or shuts down is nothing to be alarmed about. 

On the other hand, a screeching sound may indicate that a belt needs to be replaced; while a grinding sound suggests worn-down bearings. Rattling means loose parts are interfering with airflow.

In these cases, upgrading your HVAC system may be necessary to prevent further damage and guarantee proper functionality.

Inconsistent Temperatures

A possible culprit for those hot and cold spots could be an HVAC system that’s just not the right size. If your system is too small for your home, it may struggle to evenly distribute the air, resulting in unequal temperatures. A larger system may be necessary for air to be equally spread throughout your house.

Dirt is another factor that can contribute to hot and cold spots. An HVAC system that isn’t properly maintained will have dirt clogging the air ducts. This stops air from circulating evenly in your home.

To prevent this problem, schedule professional maintenance.


A musty smell could mean there is mold in your system, while a burning odor may indicate an electrical issue. Whatever the smell, it’s best to have it checked out as soon as you detect it.

The Next Step in Enhancing Your Home’s Comfort

Investing in fall HVAC upgrades is a smart move that brings you comfort, savings, and peace of mind. If you’re experiencing any of the issues listed above, Cosby Heating & Cooling can help. Serving Mt. Vernon and the surrounding areas of Ohio, we can handle all your heating and air conditioning needs, from upgrades to repairs.

Dealing with Humidity: Strategies for Controlling Moisture in Your Bellville, OH Home

Ohio isn’t considered to be one of the most humid states in the country. It barely cracks the top 20 in comparison to other states.

But that doesn’t mean you aren’t going to find yourself dealing with a humid home from time to time. When it gets very warm in Ohio in the summertime, you might struggle when it comes to controlling humidity in your Bellville, OH home.

There are, however, some steps you can take to prevent a moisture problem in your home caused by humidity. Installing a moisture control system in Bellville, OH, for example, can work wonders for the humidity levels in your house.

But this is just one of the things you can do when you’re having trouble controlling the moisture levels in your home that are the result of high humidity. Here are some of the other strategies you can put into place to make your house less humid from now on.

Improve the Ventilation in Your Home

How is the ventilation in your home right now? If the air that’s in it is sitting stagnant for too long, this could lead to your humidity levels skyrocketing if you’re not careful.

Doing something as simple as turning fans on and opening up the windows in your home every so often should help with controlling humidity in your Bellville, OH home. You might also want to keep exhaust fans in your home turned on to blow some of the humid air in it outside so that it doesn’t have an impact on it.

Make Sure Your Air Conditioning System Is Working

Your Bellville, OH home’s air conditioning system is essentially a moisture control system in and of itself. It’s designed to remove moisture from the air in your home while it’s working to cool your home off.

The problem, though, is that if your home’s AC system isn’t working properly, it might not be able to remove as much humidity from the air in your home as it should. When this is the case, you’ll want to arrange to have your AC system serviced to get it firing on all cylinders again.

This alone should help you avoid living in a humid home. You might also want to give thought to possibly replacing your home’s AC system altogether if it isn’t working and is starting to get up there in age.

Add Insulation to Your Walls

Are there parts of your home that have either very old insulation in the walls or no insulation at all at this point? This lack of insulation could be contributing to the humidity problem in your house.

When you don’t have enough good insulation in your home’s walls, it can be difficult for your house to maintain a consistent temperature. This can sometimes lead to condensation, and this condensation can add to the moisture levels in your home’s air. It’ll eventually result in your humidity levels spiking.

By adding insulation to your walls, you’ll be able to control moisture and humidity more effectively. You’ll also be able to keep your home in Bellville, OH at a more comfortable temperature throughout the year.

Seal Any Cracks in the Exterior of Your Home

If you happen to have any cracks in the exterior of your Bellville, OH home, they could be allowing humid air to come right inside of it during the summer months. This humid air is going to add to the humidity that already exists in your house and make it so much worse.

The cracks in the exterior of your home could also potentially invite pests to come inside both during the summer and other times of the year. For all these reasons, you’ll want to work on getting any cracks in your home sealed up ASAP. It’ll be so beneficial for your home in a variety of different ways.

Consider Drying Your Clothing Outside

Is your home’s clothes dryer running almost all the time to keep up with your laundry demands? It could be one of the reasons why your Bellville, OH home is more humid than you’d like it to be.

The solution to this problem might be drying your clothing outside as opposed to continuing to dry them indoors. At the very least, you might want to begin drying at least some clothes outside to give your dryer a break and cut down on how much moisture it’s letting out into the air inside.

Keep Pots Covered When You’re Cooking

This might seem like a small thing. But if you leave your pots uncovered when you’re cooking meals, they can let out a large amount of moisture into the air. This moisture can then contribute to your home’s humidity problem, especially if you get into the habit of cooking like this all the time.

By simply covering any pots that you have out on the stove, you can stop moisture from working its way into the air in your Bellville, OH home. It could make a big difference when it comes to controlling moisture and humidity.

Arrange to Install a Moisture Control System

Have you tried almost everything on this list already and come up empty as far as controlling humidity is concerned? In this case, you might be able to benefit from installing a moisture control system in Bellville, OH.

An HVAC company can inspect your home to see what could be causing the spike in your humidity levels and let you know if installing a moisture control system would be the right move to make. It might help with the humidity issues you’ve been having.

The Benefits of Professional Maintenance for Your Air Conditioner in Fredericktown, OH

By Cosby HVAC Blogs

Keeping your AC unit healthy and running for these summer months is essential. That is why it is important that you have professional maintenance done on your air conditioner. 

Luckily, this is not hard to find in the United States. There are nearly 660,000 people that work in this industry.

What are the benefits of working with an HVAC contractor? Here are some of the biggest pros. 

Lower Your Electric Bill 

Believe it or not, working with a professional HVAC contractor can help you save money on utility bills. This includes your electric bill during those hot summer months. 

On average, Americans pay $122 per month for their electricity. While this can obviously vary depending on your location, the condition of your air conditioner will play a part in this. 

An example could be if there is a leak or some other major issue with your air conditioner. When this happens, it can take more power for your air conditioner to run properly. As a result, using more power means that you would end up paying a higher electric bill. 

This could mean that you end up paying double what you normally would for utilities because you have an undiagnosed issue with your air conditioner. 

How does having professional maintenance help with this? Well, if you do this routinely, it is likely that an issue like this would be caught before it even makes it to your electric bill. Essentially, a professional contractor can help you keep your electric bill where it belongs. 

Avoiding Bigger Problems 

Another benefit to having routine professional maintenance on your air conditioner is that this can help you avoid bigger problems with your AC unit. If you do not call someone in to check on this once in a while, you could end up neglecting the unit and have a bigger issue with it developing. 

An example can be if there is a leak in your air conditioner. If you allow that to spread, it can get into the pipes of your house as well as your refrigerator unit. Then, more extensive work would have to be done to fix the problem. 

That may result in more time spent on a bigger project along with thousands of dollars down the drain. 

How can you avoid this? You simply need to make sure that you schedule routine maintenance before minor problems have the opportunity to become bigger problems. 

Take Advantage of a Warranty 

When you purchase an AC unit, you will likely receive an option to get a warranty on that unit. However, the catch with this is that you will have to meet certain conditions to do this. 

One of those conditions is likely to have it worked on by a professional within a certain amount of time. For example, let’s say that you purchased the AC unit two years ago. The warranty may be good for five or 10 years before you are on your own. 

However, if you neglect your air conditioner or have it worked on by someone who is not a professional, you may be stuck covering damage and replacement parts yourself if the previous job did not meet professional standards. 

So, save yourself this potential headache down the road and work with a professional from the beginning. 

Increase the Lifespan 

Along with avoiding major repairs for your air conditioner, you can also potentially increase the lifespan of this unit. That is because, if you are able to spot minor issues early, you will likely avoid causing significant damage to your air conditioner. 

If you take good care of your air conditioner, it can last a long time. While it is normally good for a little over a decade, perhaps you could stretch its lifespan to more than 20 years with the right maintenance. 

Considering that an air conditioner typically costs thousands of dollars, you are likely going to be happy if you do not have to worry about that expense for an extra decade. Make a minor investment into professional maintenance to save you this cost in the long run. 

Peace of Mind 

Finally, hiring a professional allows you to have some peace of mind when it comes to your air conditioner. You are sure that they are qualified to do the job and you trust them to know every part of your air conditioner. 

Imagine if you take a look at your air conditioner and notice a leak is coming out of it. If you refuse to use a professional, you may end up hiring an amateur or trying to fix it yourself. However, the thought of finding out the exact source and doing the proper job to fix it can be daunting. 

Plus, if you or an amateur does a bad job, you could be left with more work and more expenses. Hiring a professional can eliminate this concern because you can be more confident that the job will be done right the first time around. 

Use Professional Maintenance 

These are just a few of the benefits when you use professional maintenance for your air conditioner. You can avoid running into bigger problems with your air conditioner, save money on your electric bill, use any warranty that you have on your AC unit, increase the lifespan of it, and give yourself peace of mind. 

When you factor all of this in, why would you not want to hire a professional?

What Are Geothermal HVAC Systems and Do I Need One For My Howard, OH Home?

By Cosby HVAC Blogs

A survey showed that 88% of US households rely on their AC every year. This helps keep your home at a comfortable temperature and gives you more control.

There are a variety of HVAC system options available to homeowners. One of these options is a geothermal HVAC system that has many benefits.

If you need to replace your HVAC system, this is worth considering. This guide will help you understand how geothermal HVACs work and their benefits.

Keep reading to find out what is a geothermal HVAC system.

Understanding Geothermal HVAC 

A lot of people have never heard of different kinds of HVAC systems. When it comes to geothermal HVAC, it is still not as mainstream.

This is an HVAC that has power systems that use earth temperature. This system can heat and cool your home like any standard HVAC.

A uses heat transfers between the air and the ground to use for your home. Some of these systems can even be used to heat your water.

The geothermal system is comprised of a heat pump connected to buried pipes. When the ground is warmer than the air, ground heat can be redirected to the home.

A geothermal HVAC system can also work in reverse to create cool air. It is very energy efficient as it does not require much electricity to work.

Benefits of Geothermal HVAC Systems

Depending on your situation, you may need to replace your HVAC unit. If that is the case, you may want to consider geothermal heating or geothermal cooling.

This is a great option that comes with a variety of unique benefits. Here are some examples of the benefits you may experience from this system.

Saves Energy

The majority of HVAC systems are not incredibly good for the environment. This is a reality that most people are aware of and try to find a solution to.

The good news is that a geothermal HVAC is very eco-friendly. It does not rely on harmful fossil fuels, making it a form of renewable energy.

Renewable energy is something that does not have the risk of running out. It also doesn’t have as dramatic an impact on the surrounding environment.

This HVAC system also helps you to save a bit of money as well. Your energy bills will go down without you having to use less heating or cooling.

A benefit like this is especially useful in Howard, OH. You won’t have to sacrifice comfort during the chilly winter or blistering summer.

Longer Lifespan

Investing in a new HVAC system is a pretty significant expense. This is why some people tend to put it off until it is absolutely necessary.

A geothermal HVAC is no different as it is quite expensive. But it comes with the additional benefit of having excellent longevity.

The majority of the HVAC system is located underground. Things like the pipes and tanks aren’t exposed to the elements like standard HVAC units.

Because of this, the system sustained less wear and tear over time. This lengthens its lifespan and reduces how many repairs will be necessary in the future.

Less Maintenance

Geothermal HVACs have different parts than traditional HVACs. They have fewer moving parts, reducing the risk of emergency maintenance.

As we discussed above, the majority of the unit is located underground. This protects the different parts from damage that could result in costly maintenance.

The majority of homeowners with a geothermal HVAC rarely, if ever, have to have maintenance. Although, it is a good idea to have preventative maintenance scheduled every year.

This ensures that your unit will last for as long as possible so you get back on your investment. You should go with a company like Cosby Heating & Cooling for your maintenance needs.

They provide geothermal HVAC installation and HVAC repairs.

Disadvantages of a Geothermal HVAC

When you are researching HVAC systems, you need to weigh the pros and cons. This is going to help you make an educated decision that is best for your home.

Here are some examples of the disadvantages you may experience with a geothermal HVAC.

Higher Initial Cost

A geothermal system is a less common option for homeowners. It also requires more extensive installation as most of the system is underground.

Because of this, the initial cost of the system is going to be higher. A lot of homeowners can’t afford this and will need to arrange for financial assistance.

It will take some time before you get back on your investment.

Costly Repairs

The good news regarding a geothermal system is that it doesn’t need very much maintenance. Repairs are very uncommon for the majority of homeowners.

But if something does happen and a repair is necessary, it will be more expensive. This is something you may want to consider as a precautionary measure.

Damage usually only occurs if there is an earthquake or something like a tree root infiltration.

Geothermal HVAC: What Is It and How Does It Work?

If you need a new HVAC unit, you may be considering a geothermal HVAC. This is a great option if you are looking for something that saves energy and last longer.

Cosby Heating & Cooling provides geothermal HVAC installation as well as emergency repair services. You can get all of your HVAC needs met by this dependable company.

AC Compressor Overheating? Here’s What Gambier, OH Homeowners Should Do

By Cosby HVAC Blogs

The Energy Information Association estimates that 87% of American households have air conditioning. Only 43% of Americans actually have AC maintenance done annually.

If you live in Gambier, OH, you may be having AC compressor problems. It is not uncommon for AC systems to experience issues over time.

This can happen for a variety of reasons or from wear and tear. If you suspect that your AC compressor is overheating, you need to address it as soon as possible.

Keep reading to find out what to do if your AC compressor starts overheating.

What Causes an Overheating AC Compressor?

If you suspect that your AC compressors are overheating, you may be wondering why. This is a common question since you may not understand why this issue has popped up.

The reality is that there are a variety of reasons why this could be happening. Understanding what could cause this can help you to prevent it from happening.

Bad Coils

An air conditioner has a variety of condenser coils that go from the inside of the unit to the outside. These coils will become dirty over time as they are used.

A buildup of grime in the condenser coils can start to affect your air conditioner. This can cause the compressor to overheat and not work the way it should.

This will prevent the compressor from absorbing the heat since the coolants are polluted. The compressor will have to work harder to cool your home, but it won’t be as effective.

Not Enough Maintenance

Any machine or appliance in your home requires a certain level of care. An AC compressor is no different and needs AC maintenance at least once a year.

Most homeowners neglect to do this, which can cause overheating. It can start to break down and work harder to cool your home.

When the system has to work harder, there is a higher risk of it overheating. This is especially common if there are broken pipes or damaged filters.

Too Little Refrigerant

An AC unit is made up of a variety of individual parts. One of the things that keeps the system running is the refrigerant level.

The refrigerant or coolant helps the system run efficiently to cool your home. If the refrigerant is running low, this is going to have a negative impact on the compressor.

It will begin to overheat and could even start to fail. This is why it is important to have an HVAC contractor service your AC unit annually.

They check the refrigerant levels and will be able to top it off if necessary.

Air Conditioner Size

Every home is going to need a different kind of AC unit. This often comes down to size since the HVAC unit needs to match the size of your home.

If it is not large enough, the compressor is going to be working much harder. As the compressor works harder, it will start overheating more and more.

This can result in it not cooling your home and eventually breaking down. This is why it is so important to make sure the right-sized AC unit is installed.

Signs of Overheating AC Compressor

As important as it is to understand why an AC compressor overheats, that isn’t enough. You also need to understand what signs to look out for.

This is important because if compressor heating goes unnoticed, it will only become worse. This can result in extensive AC unit damage that becomes very expensive.

Here are some common signs that your AC compressor may be overheating.

It Won’t Turn On

There is nothing worse than having your AC fail during summer. If your AC compressor fails to start, this could be an indication that it is overheating.

It may also require a longer duration between each usage cycle. This can happen if it is taking longer to cool down after each cycle of use.

If you are experiencing either sign, you should immediately call a professional.

The Circuit Breaker Is Tripping

Circuit breakers automatically trip if they sense a risk. This will happen if their circuit breaker senses that the air compressor is overheating too much.

This is why your circuit breaker may be tripping when you try to use your AC compressor. 

Excess Wear and Tear

AC units should last for many years after you have installed them. Some wear and tear is normal, but it should not be significant.

Your AC compressor may start to show significant signs of wear and tear. This is common if it has to work very hard to keep your home cool as it overheats.

How to Fix Overheating AC Compressor

If you suspect that your AC compressor is overheating, you may not know what to do. This is a problem that you should not try to fix on your own.

AC units are complex and require professional HVAC services. This is the only way to guarantee that the problem will be discovered and fixed correctly.

You can schedule an appointment with Cosby Heating and Cooling for AC repair and maintenance. A contractor will check your unit to see what is causing the problem.

They can also advise you on how to prevent other AC compressor issues. This is much more cost-effective than paying for a serious repair or a new AC and severe instances.

AC Compressor: Overheating Troubleshooting

If you live in Gambier, OH, you may be worried about your AC compressor. It is not uncommon for an AC compressor to overheat, and you need to know what to do about it.
