"From the moment I spoke to Marissa when I first called AiRite about securing a replacement for my 22 year old Trane HVAC system, I knew I found the right vendor. She explained (without being asked) how modern residential HVAC systems worked; offering up advice on two stage compressors, system pressures and the new coolants now being used. They had an experienced tech at my place by the next day; he performed a thorough inspection of my home. By the next day I had an estimate in place. I can assure you that AiRite was extremely competitive compared to other quotes I had received from some of the bigger names in the Phoenix area. Install was scheduled for just a few days later (they had to secure the Trane HVAC unit I wanted). Two installers arrived about 10 minutes before their scheduled start time (if you're not early; you're late in my book). I have a home office, and during the four hours of installation time, I barely noticed them. They were courteous, professional, efficient and thoroughly cleaned the job site before leaving. If you are looking for a trustworthy, fair priced, courtesy HVAC vendor, look no further than AiRite."
