"My heat pump which had been installed 2 years ago by FH Furr suddenly stopped working Sunday afternoon. With the heat warnings in effect, I knew I needed help, FAST! Blair arrived this morning abd diagnosed the issue and replaced the condensation pump. These new "smart" systems have more brains than some humans!! When the pump failed, it shut down the entire system. However, Blair had the old school know-how and work ethic to get my system back online and back to normal. I have seen a nice change in technicians in the last 2 years and am always pleased to have them come out and fix any issues I may have. Keep up the good work!!"

"The project was completed seamlessly and Jim and his helpers were competent, hard-working and didn't mind explaining what was going on every step of the way! His years of experience are evident, and make him a great diagnostician and problem-solver. He even went out to buy stone to line the bottom of the trench dug outside of the house to insure that the new pipe would be stabilized underneath! There were a number of things that could have been complications (like tree roots, and breaks in the pipes going to the septic tank), but it was clear to me that Jim would be able to address them, if they did surface. This was the kind of thing that makes a homeowner very nervous, so I was so relieved that I had Jim do this work. Experienced, competent, honorable, and a really nice guy! So glad that I won't have to conduct searches for a plumber in the future!"

"Naturally, on the hottest weekend of the summer in 2019, with a houseful of guests for that weekend, the capacitor went. Normally, I'd order the part and fix it myself, but that would have taken days to acquire. Air Temp showed up first thing in the morning the following day, and quickly verified the broken part and replaced it. Sure, of course it was more than doing it myself--but that's not the point. They were timely, had the part in hand, and were extremely reasonable on the price. We use them for our annual AC and heater checkups as well and will continue to do so for the foreseeable future. I highly recommend the team."
