"Mr. Ferrell worked with my husband over the phone to fix the problem. It was surprisingly fast and stress-free. To have the work done remotely in less than an hour was wonderful."

"Happy with the service! Installed a new furnace and AC. Have used him several times and trust him for my all my HVAC needs!"

"Spoke with Mr. Ethridge first thing Monday. He was able to send a tech out between 10-12. Andrew arrived on the early side of my window and was able to diagnose the source of the problem within the first five minutes. Fortunately for us, it was an inexpensive fix as he found a wire had come off the condensation pump. He properly reattached the wire and the condensation motor started as soon as the breaker reset itself. Another less reputable company could have told me I needed a new unit. Ethridge and Andrew just became my AC contractor!"

"Although the weather was a major factor and also materials ordered, once everything fell into place, the job was done very quickly and professionally. I will continue to use this company for any roofing needs and recommend them to anyone needing any type of roofing repairs or installs."

"Overall, we were very satisfied with the knowledge and quality of work that Covenant LLC provided. We had Covenant LLC install a radon mitigation system for our basement. Initially my husband and I met with David for the estimate and consultation. David spent the time to explain how radon can get into the basement, what the system would look like, and how he was going to make sure it was working. After meeting with David at Covenant, we met with a competitor who were definitely not as knowledgeable, were not going to seal any of the cracks or holes in the foundation or even follow industry standard by venting through the roof of the house. The day of install the crew was personable and professional and if they had any questions, they asked. The 3" pipe that Covenant had to install to run through a closet and into the attic. In order to do this, they had to drill through the porcelain title floors and run through 3 shelves. They spent extra time to jig-saw cut the shelves around the pipes and they took special care not to crack any of the porcelain tiles and when finished it looked like it was built with the house. After completion, Covenant came back and tested the radon levels which were reduced to below their guarantee, which itself is orders of magnitude below the EPA limit. We were probably not the easiest clients to work with as we had Covenant move the roof penetration several times until the noise was completely unnoticeable. David was always polite and professional and he wouldn't be satisfied with the job until we were satisfied. We highly recommend Covenant Air to anyone who is considering these services."

"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."

"Went great did everything in a professional and timely fashion. Id recommend them to anyone who needs hvac work done"
