We've been having problems with our air conditioner for more than a year. A number of service people have tried to fix it, but none were able to figure out the cause of the problem. They would get it working but then a few days or weeks later it would break down again. Mike figured out the cause of the problem and then ran across town in rush hour traffic to get the part that we needed. He also pointed out that one of our ducts wasn't attached properly and was probably driving up our monthly electric bill. Mike's prices are fair, he responds quickly and he does quality work. Absolute Air Technologies is a great find. Definitely worthy of 5 stars!
