"I am very pleased with the work done for me last week in repairing my gas furnace. Another company had tried to repair it and could not and was in the process of ordering a very expensive replacement part(s) when I decided to cancel and look for help elsewhere. I contacted your office and your tech came out…diagnosed the problem…then proceeded to correct the problem without the need for expensive new parts. Your tech took the time to dissemble and locate the failed element which basically only required slight adjustment to correct completely! The cost was minimal compared to what the cost of replacement components would have been! Your tech knew his stuff and was great! I’m so glad I’ve found a company I can trust to do the job correctly!!"

"I normally don't write reviews, but One Source Heating and Cooling instead saved me! My house was FREEZING and with a young child at home, I needed help fast. The office staff was friendly and helpful from the start, sending a service technician out shortly after. I even got a phone call when he was on the way, which helps so much when you have kids. Instead of trying to sell me a new unit, the tech was professional , and fixed our heat in no time. I could tell he was very knowledgeable about heating and air, and not just trying to make a sale. I am so thankful for the service I received, I even got a call back a few days later making sure everything was okay. I highly recommend them for any heating and air issues."

"Fantastic. Submitted a request via AL Sunday morning expecting to be called back Monday. Got call about 3pm asking if I still needed service that day. Inquired if there was an extra service charge for Sunday and told no and the fee would be waived if they made the repair. Technician (Daniel) was there within an hour, diagnosed the problem and had it corrected inside of an hour. Fantastic service. Will use again. Highly recommend."

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."

"I think there work is good. I will not know for sure for a while I guess. The only problem is it took weeks for them to complete the job. In fairness, it did rain a more than normal amount during those weeks, but there were days of dry weather when I wondered why they don't come and do this small job. I wish them the best and everyone I talked to was professional, but I got frustrated."

"I discovered elevated Radon levels throughout the house using commercially available meters in March of 2014. These
levels ranged from slightly above the EPA-recommended upper limit of 4 pCi/L to as high as 13. A local provider
of basement waterproofing systems enclosed the crawlspace and installed their Radon system. Readings inside
the house actually increased !
David Coffey of Covenant Air inspected the house and correctly diagnosed the primary Radon source...a poorly-designed
and constructed area near the main heat pump return ducts. He solved the problem and levels throughout the house
are now well below 4 !
My education includes degrees in physics and medicine, but David has a "Doctorate" in Radon mitigation !
