  • Very courteous staff. The technicians are very thorough and willing to make things right. Very customer oriented. Thank you, Powell Brothers for our HVAC install on, this 95-degree day!  - Patty D.
  • We got exactly what we asked for in a timely manner! Thanks Powell Brothers!  - Charlie H.

  • Powell Brothers is the best!  - Jeff W.

  • Powell Brothers is one of the most honest contractors left. Thank you for being honest.  - Patrick H.

  • We are pleased with our service. Your techs always do a good job!  - Jesse J.

  • So glad we called on a provider that treats customers like real people instead of just a necessary part of staying in business. We are very satisfied with the experience we had with Powell Brothers (Kenny & staff) from start to finish. Thank you for a great job!  - Antioch Baptist Church

  • Very helpful in an unusual situation. I won’t use anyone but Powell Brothers.  - Roger P.

  • Kenny came out at 10:30 at night (in Nov.) to get the heat back on for my family. Also, came on a Sunday afternoon, he knows my wife is serious asthmatic and has always came or sent somebody when I called.  - Ron Y.

  • Great service and professionalism. Powell Brothers is our ‘go to’ for repairs to air conditioning. A huge thank you for coming so quickly during on the hottest days ever!  - Cristen H.

  • Honest and reasonable repairs and preventative maintenance from Powell Brothers. Very friendly and knowledgeable. Powell Brothers have been in the HVAC business for longer than I can remember.  - Doug M.

  • Great working with this honest, hard-working people. Highly recommend Powell Brothers!  - Lori L.

  • Called Powell Brothers at 5:30pm to inform them that our AC at the house was not working (they installed 5 years ago). They told me that they would be there in the morning. Got home that same afternoon and saw Jeremy was already there and changing the capacitor in the back - that is an outstanding employee and a wonderful human being. We appreciate it VERY much given that the temp inside was 81 degrees and we have small children.  - Sam A.

  • Kenny Powell has always been responsive to my needs. He did an excellent job replacing my worn out heat pump recently at my old house and now he is installing a new dual fuel system at the house I am building. He took care of all my insulation needs and encapsulated the crawl space at my new house. His crew does excellent work and in a timely matter.  - Larry C.

  • I've had the best possible experience with Kenny and his crew. They did the geothermal HVAC system on our new house, as well as the gas lines, kitchen vents, and insulation. Kenny is professional, knowledgeable, prompt and fair in his pricing. Whenever there are issues with the HVAC, which is brand new technology that still has a few kinks, he is quick to respond, follow up with the manufacturer, and get it sorted out. I will be using Powell Brothers again as we add a pool and other features to our house.  - TD

  • They came out on a Sunday and repaired my air conditioning unit, which had failed. Considering the circumstances, I thought the charges were quite reasonable.  - William P.
