Get matched with top heating oil pros in Pendleton, SC

"Outstanding work. The crew was on time, respected my home, and was knowledgeable and professional. They ensured the system was fully functional and answered all my questions as they walked me through operations. Great team."

"This company specializes in Trane, probably the best brand. I am very satisfied with their work. I recommend them without reservation. They carefully and quickly prepared a quote. They completed the job (installing a new heat pump) on time, at the quoted cost, and even did some extra small repairs of my other heat pump. They did the job for substantially less than quotes I received from larger companies. They are a pleasure to work with."

"Work was done in a timely matter and Kieth was very polite and explained everything. System is two years old and is working well. Had one switch go bad and was under warranty that Kieth replaced."

"We purchased a new Clayton home in late 2023 and everything seemed good at first. After several times over a year of having HVAC techs from Clayton come out for a cooling issue, eventually the warranty ran out on the AC. Then we had another supposedly reputable HVAC company come out and said it was a lot of issues outside and would cost almost $2000 for a repair that may or may not work. We went thru Angis list and got in touch with Quality Air. The tech came out and went thru our system and located the issue inside that was never installed from the Clayton homes store. Nathan had our system up and running and has been cooling excellent ever since. Before, our system had a very hard time keeping up with the selected temp.. but now we sit in cool comfort and it has never ran so great. Thank you Nathan, and thank you Quality Air!!"

"Sunday emergency service call. Jake was prompt, courteous, and thorough. He has excellent diagnostic and technical skills. We're very impressed with the professionalism we have experienced with One Hour Heat And Air."

"Excellent service Bryan was friendly and did excellent job servicing heat pump/air conditioner. Would highly recommend !"

"Very knowledgeable about the unit got my heat fixed in no time …thanks so much"

"The installation and time of response were good. The price was fair. The reason for the ?three star? grade was what happened afterwards and is still ongoing. I wrote a check for the full amount of $10,704.00 on 8/17/26. I am 87 years old and not too computer literate so I asked for a hard-copy of the warranty information and bill-of-sale. I?ve called a couple of times but so far haven?t received anything. Can you help?"

"Here’s a polished, glowing review you could use: I cannot recommend Chase highly enough. He installed our new HVAC system last year and our tankless water heater this year, and both experiences were outstanding from start to finish. Chase was incredibly responsive whenever I had questions, always taking the time to provide clear and helpful answers. His communication was excellent, and he consistently showed up exactly when he said he would. Both projects were completed promptly, professionally, and with great attention to detail. It’s rare to find someone who is not only highly skilled at their craft but also dependable, honest, and easy to work with. If you’re looking for someone you can trust to do quality work and stand behind it, Chase is the person to call. I will absolutely use him again for future projects."
