An extremely professional and very knowledgeable tech named Jeff came over to diagnose the situation with my heating system. He took the time to show me the problem, what caused it, how to fix it and how to mitigate it moving forward. I will absolutely continue to use them for my future HVAC needs including an annual maintenance plan. I would also refer them to family and friends.

We have had Fresh Air do our furnace and AC service for a number of years. Always professional, on time and very responsive. They do excellent work and make recommendations when there are opportunities for us to take advantage of new services or technology. Never pushy, just matter of fact. Love Mike Bommarito! We always request him as he embodies all of the great things we like about Fresh Air. Highly recommend them!!

Our air conditioning went out yesterday afternoon. I called right away thinking it was going to be a long wait for them to be able to come out to look at the unit. They were able to come yesterday evening at the normal rate and it was all fixed before they left! We never had to go a night without air conditioning! Such great service as always! Thank you!!!

I have used Fresh Air Heating and Cooling for several years now. Their technicians are always prompt, friendly and professional. When I needed new AC units installed, I used Fresh Air to purchase and install them. They also replaced my water heater a few years ago, with seamless installation. Mike was my technician today and has been to my house several times. He ensured that both of my AC units were checked, clean and functioning properly. He is always friendly and I appreciate his attention to detail. I would highly recommend Fresh Air Heating and Cooling!
