     Installed a new furnace in my 150-year-old house without any difficulties, it was done in a day. This company is old-fashioned service and fantastic quality. Totally worth it!

     I have had Levi in my home to help install my Hvac. He is a good tech and knew quickly what the issue was. He did a great job and I am warm once again. My condensation drain hose was froze up. My line runs outside of the house and I did not think of checking that. It has never happened. A few trips to the kitchen sink getting hot water and I was back in business. Thanks once again.

     Joe from Cosby is the best tech. Honest, skilled, experienced, courteous.
He services furnace and a/c twice a year, follows the specs for our furnace. When we wanted to improve the air return flow he designed and installed a wider duct to improve air flow caused by a bottleneck. Reasonable prices for highly skilled work.

     Good, responsive local company. Adam was efficient and knowledgeable answering all of our questions. The purchase decision was tough and we went with a competitor solely because we had purchased their product line in the past. I would recommend Cosby.
