I received a diagnosis of the problem. The technician was very nice and explained to me what the problem is. I still have work that needs to be done and will still be using Air-O-Stat for it. Great service, very professional.

Very pleased with how quickly Air-O-Stat responded to my inquiry. They immediately found the cause of the issue and were able to fix it fast. The servicemen were incredibly polite and courteous. Happy to have worked with them.

Just a great experience. We had many other people in to look at our old commercial air conditioner. Armen with air-0-statWas the only one who really explained exactly what was going on and then he stayed into the evening and got it all fixed at an unbelievable price much lower than anybody else. Itworks perfectly Wethought we’re going to have to replace the whole thing to the tune of 7000 and he only charged 750. A great deal, Another company quoted us much higher but no guarantees. He was determined to make it work. I will probably hire them for my home too really happy with the experience

The technician with Air-O-Stat was fantastic! He arrived on time, was able to assess and fix the problem in ten minutes. I requested, got an appointment, and got my A/C fixed all in one day. They were professional and kind. I would absolutely hire with them again for any future A/C problems.

3 people came out to look at our problem, and the first 2 said it could not be fixed without breaking walls in order to access our furnace. Air -O-Stat were the only people able to address our issue and fix it quickly, effectively and reasonably priced. Highly impressed. I would rate them 6 out of 5 if I could
