HVAC FAQ’s Mt. Vernon, OH
Understanding your home’s HVAC system can be tricky. The team at Cosby wants to answer some frequently asked questions.
In order to keep your HVAC system running at optimal service, it is best to have a professional maintenance inspection twice a year. A trained technician will be able to identify problems so that you are ready for summer heat and winter cold. Filters, wires, and other important parts will be examined so that things work efficiently and keep your home at a comfortable temperature throughout all four seasons.
Although it is common to hear small noises when your system is running, cracks or loud bangs may be signs of a problem. For example, a humming noise may signal a broken fan motor. To diagnose the issue, it is best to call a professional technician.
Many causes may lead to uneven home temperatures. For instance, your HVAC may not be circulating air efficiently. Air filters may need to be cleaned or replaced. Also, insulation may need to be added within your walls or ceiling. Ductwork may be leaking as well. An expert will inspect your home and will uncover the issue.
When selecting an A/C unit, you must consider its size and its power. Although most people believe that bigger is better, this is not always the case. According to the U.S. Department of Energy, a unit that is overly large may not work as efficiently as a smaller one in a confined area. A professional technician will be able to assess the size of your space and recommend the correct unit. In many cases, a custom-sized central A/C system will be fitted for your home.
The age of your system will dictate when a new unit will be necessary. Usually, when your system becomes 15 years old, it may require frequent repairs. Also, it may begin having trouble heating or cooling your home correctly. As a unit becomes older, it has difficulty working at top efficiency, which can raise your utility bills. At this point, it is best to consider a replacement.
There are a number of ways to decrease your monthly utility bills. For example, you may consider installing a programmable thermostat. Also, you can make sure that your doors and windows are adequately sealed. This ensures that outside air is not allowed to enter your home. This helps your HVAC system run less.
When a popping sound is occurring, it may be a sign that there is a poor duct design in your unit. There is too much airflow. Besides the noise, you may notice extra energy usage, irregular heating or cooling, or system malfunction. When you notice popping, it is best to contact a professional HVAC expert.
When airflow is restricted, the unit’s evaporator coil freezes up. This problem may be caused by low refrigerant levels as well. As a result, the unit becomes too cool, which forms ice. When this happens, it is advised to turn off the unit’s thermostat and to call a heating and cooling expert.
A zoning system helps to avoid hot or cold rooms throughout a home. It is a smart idea for a house with multiple floors. With this type of system, it is possible to customize the control of hot or cold air. Ductwork keeps air flowing. Dampers are used to direct air as well.
HVAC filters are available in different sizes, qualities, and features. Each filter has a MERV rating, which explains its efficiency reporting value. A higher number means that the filter catches finer particles. This may sound good, but your unit must be equipped to use this type of filter. If not, it may restrict the flow of air in the system. A good filter will catch things like pet dander, dust, and pollen so that you have cleaner air moving through your home.
There are many reasons why your gas furnace won’t ignite. To begin, a breaker may have tripped. Also, the electric igniter system may have become broken. If you have dirty or rusty burners, oxygen supply may not be adequate to ignite as well. Also, a dirty air filter may be to blame. If you can’t find the problem, it is best to consult with a trusted HVAC professional.
The most common reason behind a leak is a problem with the flue. When this pipe is too tiny, heat may become trapped. With time, it cools and turns moisture into a liquid. This ends up leaking outside the unit.
If there is a high-efficiency gas furnace involved, it may be linked to a blocked drain system line or a damaged heat exchanger.
