One Hour Air Conditioning & Heating of Mount Airy has been a pleasure to work with, and I highly recommend them. They are consistently punctual, communicate clearly about arrival times, and always stay until the job is completely done. Their technicians provide excellent service, are professional and knowledgeable, and take the time to explain what they are doing and answer any questions. Everyone I’ve interacted with has been friendly and respectful in my home, which makes it easy to feel comfortable having them work here. They also treat the house with care, protecting work areas and leaving everything just the way they found it when they are finished. For reliable, high-quality heating and air conditioning service, One Hour is an easy choice.
Tyler was great! He came out to service my system and did an excellent job from start to finish. He quickly diagnosed the issue, explained what was going on in a way that was easy to understand, and got everything back up and running perfectly. He was on time, polite, and clearly knows his stuff. You can tell he takes pride in his work. I’d definitely recommend Tyler to anyone needing HVAC service!
Tyler was awesome! He came out to check my system and found that my indoor fan wasn’t working, which I had no idea about. He explained everything clearly and was able to get it fixed. The air and heats running great now and the house feels so much better. He was professional, quick, and super polite. Definitely recommend Tyler !
Damon did a great job. Worked with me when the thermostat didn’t initially turn the heat on but I was able to by my phone and then everything worked. He tried to provide upgrade ideas and also help set the drain slope to ensure it drained better. Thanks Damon.
