I've been a customer of Fresh Air for many years. They sell high quality equipment (my current furnace and AC units were both purchased and installed through them) and provide outstanding service (their annual maintenance program is a great deal that keeps the equipment in top working order). Their technicians are alway courteous, knowledgeable, and conscientious about keeping my home and the work area clean.

The company, Fresh Air, was extremely accommodating and were able to give us same day service to repair our a/c system, which was sorely needed in the middle of a heat wave! The technician was very courteous, explained in detail what repair was necessary and why. Prompt friendly service at a very reasonable price. I highly recommend Fresh Air and plan to utilize them for all our HVAC needs in the future.

We used Fresh Air to diagnose why our A/C unit was no longer cooling. They were extremely responsive and had a tech come out right away. This was particularly appreciated since it was a Friday evening and they were the only HVAC company to respond. Our tech Brad was very kind, professional, quickly diagnosed a Freon leak; he added more Freon and was on his way in no time. Problem effectively resolved! We were very impressed with Fresh Air's service and won't hesitate to use and refer them again!
