"VERY HAPPY WITH THIS SERVICE! Jesus was a great help to us throughout the entire effort. Not only did he come in with a great quote, beating out their competitors by a considerable margin, the service was professional, timely, and thorough. They did not upsell us on things we did not want or need, and afforded us the flexibility to cherry pick parts of the work we preferred to do ourselves to save some cash. Every interaction was friendly and, most importantly, the work was done extremely well... our testers and inspectors even made a point of telling us how much they appreciated the quality of the work. They started the work quickly and wrapped up in record breaking time. I will undoubtedly call them again for my next project and I am already recommending them to friends."

"Air Tech was great. I would HIGHLY recommend. I initially had 2 other companies besides Air Tech come out for a replacement estimate. Price wise Air Tech was right in the middle but were doing a lot more than the other 2 quotes I got. For example they were changing the copper refrigeration lines, which the other 2 weren’t going to do. When I called the other 2 companies to add the lines in there was going to be an additional $1500-$2000 charge. I’m very pleased with this the work that was done by Air Tech"
