“Had a few different services out to get some sort of heating/cooling installed for my house. Unfortunately, while a good house, everything about it upside down, backwards, crooked, and inconvenient. Dustin came out to take measurements and put together an estimate with a couple of options. He was extremely nice and friendly, didn't talk to me like I was stupid, nor mention any of the quirks of the place like some of the other services. Which did play a roll in my decision making. Poor Dustin was also very patient and essentially had to hold my hand with all the questions I had, because I just know nothing when it comes to houses and doing this sort of thing. The guys that came out were also super nice. I get optical migraines, so every place in the house and light bulb is insufferably dim, but they had their own lights for what they needed. They were very quick and efficient, and one of the men was also nice enough to let me know when they were done in the main area so I could let my dogs back in. And, I wish I had gotten the name of that man-- he's the one who installed the heads. He absolutely has putting those in down to a science. I am so wildly impressed that he managed to get one installed in the living-room. It truly fits perfectly, there was no room for error and he absolutely nailed it. Wendy at the office was also very nice and helpful. All of the communications with her and Dustin were very quick and efficient. Given the lack of space in the crawl and attic, we ended up having to install a mini-split with two heads. My husband was rather cynical about it. But, so far, we've only had it set on the 'dry' mode and it is truly shocking how cold it feels in the house vs outside on just that setting alone, which seems to have won him over. I'm looking forward to see how it does throughout the more serious summer heat, but at this rate it does seem as though it'll really keep up!”

“I had an issue with my HVAC system when both the AC fan and capacitor went out. I called One Hour in Chattanooga and they responded quickly, sending a technician out the same day. Danny was professional, knowledgeable, and had everything needed to get my system back up and running. Pricing was fair, and they took the time to explain everything clearly. If you’re looking for a reliable HVAC company in Chattanooga, I highly recommend them!”

“We recently moved to the Chattanooga, TN area and needed HVAC services right away. After doing some research, we decided to give One Hour Heating & Air Conditioning a try, and we are so glad we did! From the moment I called to schedule an appointment, their customer service was friendly, professional, and quick to respond. The technician, Danny, arrived on time and was incredibly knowledgeable. He quickly diagnosed the issue with our air conditioner and explained the necessary repairs in clear detail. What stood out most was the level of professionalism and efficiency. The service was fast, affordable, and done right the first time. It's evident that One Hour Heating & Air Conditioning is committed to providing top-notch service and high-quality work. They truly live up to their name, offering fast, reliable, and expert HVAC solutions for all your heating and cooling needs.

“Our AC went out and we had One Hour come to check it out. We ended up getting a new HVAC system. We paid exactly what they quoted us. When the furnace didn't turn on the first time we tried to use it (weeks later), they came right out and fixed the issue. They arrived within their time window every time and everyone was friendly. Specific shout out to Chris who was very polite, friendly, and explained everything. Would recommend this company!”

“I highly recommend One Hour Heating and Air for any of your HVAC needs. During extreme weather conditions our unit started acting up and it just so happened to be a holiday week. I contacted One Hour about the issues I was having and requested a service call. The lady who answered the phone was extremely nice and they came out the same day and had the unit repaired the next day even with a part having to be ordered. This company is professional, reliable, prompt and friendly. Thank you!!”
