One Hour Heating & Air Conditioning® of Chattanooga

"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!!"

"Our AC went out Monday night. I called One Hour Air at 8:30 Tuesday morning and they fixed it before noon. $250 for part and labor. Excellent service. Will certainly use One Hour Air again."

"I have utilized One Hour several times now and have been pleased each time. They try to come as quickly as possible & have reasonable prices. Emily, who has since left to pursue other interests, was first tech. She was great. Chris has been the one to come out each time since then. He is fantastic. He explains everything & gives rationale behind it. He worked on my AC few wks ago & warned me that it is not likely to keep up with hot temps coming because the unit is 20 yrs old. He was correct. So after AC running 79-80 I called them 1st thing Monday morning. Terry & Jacob installed a new unit on Thursday. Dustin came on Tuesday to give estimate & see what to order. Wendy got on it and ordered parts to be arriving Wed afternoon. She told me about when Terry & Jacob would be arriving and how long it could take to install. They worked hard for 8 hours minus a very short lunch. Wendy and the other ladies up front are great. But Wendy "feels your pain" and does everything possible to get someone out as quickly as possible. Great company. Great customer service."

"One hour has done my HVACs PMs, maintenance and installations for many years. Wendy in the office goes way over and beyond to make sure the work is done in the time frame quoted. Rick is outstanding for PMs and maintenance. Terry and Jacob just installed a new unit and was very pleased with their work and how they answered questions that I asked."

"One Hour is a great company to work with! Wendy is awesome"

"Amazing company to work with!"

"This is the best service I have had and s long time people on time caring and know what they are doing."

"My mother called last Wednesday afternoon for emergency service on her HVAC unit, which was not working. A technician named Chris came Thursday afternoon (a very prompt response, considering the extremely low temperatures and icy conditions), and evaluated her unit, took pictures of the broken part, and showed my mother exactly what needed to be repaired. He returned Friday morning with the necessary part and had the repairs done quickly. Chris showed Mom the broken part and helped her reset her thermostat. She was very impressed with the service and the technician. We are grateful that her home is toasty warm now."
