Best Heating & Air Conditioning / HVAC In Mount Vernon

“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.“

“We have had multiple experiences with Peterman Brothers and they always do an awesome job. Andrew has been to our house many times and we feel really confident in his skills and his opinions. We are very grateful to have a heating and cooling company that we really trust.“

“We've used Cosby for several years now to service our furnace and air conditioner. We had spent over $1000 in the year after the warranty on our furnace ran out. No more, we called Cosby and since then (10 yrs) we've spent about $35. over the annual service fees. The guys are friendly and really know their business!“

“I would highly recommend Xtreme Air to anyone looking for HVAC system maintenance and repairs. They are professional, responsive, and maintain clear communication throughout the entire process.

Their team is honest, skilled, and fair. Making them a pleasure to work with. They’re also incredibly reliable, and I can always count on them to get the job done in a timely manner.

A special thanks to Mike and the entire team for consistently delivering 110% in customer service.“
