“I called MAINair when my unit started blowing smoke. They managed to have a technician at my house first thing the following day. The technician was very friendly and professional. My unit was 15 years old and I chose to have a new unit installed and the technician was able to do the install the same day. I could not be happier with the service a received.”

“My air conditioner broke down on a 40 degree day in the middle of summer and everyone I called was booked out for a week and then I called MAINair and luckily they were able to have someone out that same afternoon who managed to fix my air conditioner on the spot. Without Quick Air I would have had a very uncomfortable sleep that week!”
