Clayton and his son did a wonderful job on our new gas pack unit. They were right on time and fixed additional little problems while they were here with no extra charge. :”Try to get that anywhere else” The price was great and he followed up the next day to make sure it was right. Thanks Clayton for the great service and deal !
The Squirrel Chronicles Aka Rescue's
This business is run by Clayton Brown. He was referred to me by a neighbor who has utilized his AC company for years. In this day and age when it’s hard to trust some contractors….Clayton is one of the most trust worthy people I have met. He is an absolute professional and a master of his craft. I had about the most complex and unusual situation someone could have with their AC….Clayton was able to troubleshoot the issue and offered up the best solution. He went above and beyond. His employees are exceptional as well. He is a small business so he can’t always respond immediately but he is worth waiting for and is very good communicating and scheduling. I will never use anyone else for all my heating and cooling needs.

Frank Parker
We had A/C problem with our upstairs unit blowing out warm air for almost a week. Found Keith Brown’s heating and air on Angie. Clayton came out had the unit up and running quickly. Cleaned the coils on both units ( because I let maintenance slip for a few years ) we have cold air in the house. Clayton did a great job diagnosed the problem quickly did not try selling me anything I didn’t need. I’ll be calling him again to keep the maintenance up on our A/C and furnaces. Great job, great tech, great price . I highly recommend Clayton and Keith Brown’s heating and air.

Now I can say I've got an AC Heating guy. Clayton was on time,honest, & affordable. Please guys don't bother with anyone else Lake wylie and beyond..
Johnny Wilson
Clayton was referred by another professional whose opinion I trust. He came within hours, actually had the part (which is unusual in my past experience with other HVAC companies) and didn’t leave until he knew the unit was working properly. Clayton was very nice, very professional and reasonably priced. I highly recommend this company.

P Mac
Called him out for my unit immediately tried to talk me through what to do educated me on everything about my unit and helped me and was more than willing to come out and fix the problem also was willing to warranty out parts and get me my money's worth. Honest and amazing man to say the least. I've had horrible experience as a woman as a disabled person with getting ripped off or charged more than what was really needed to be done and it have to say he's the most honest person I've met in a company and I really appreciate to call this company they are awesome and I will never call another h but company for as long as I live and on my home. Thank you guys so much for keeping my system up.

Excellent service and fair prices. We've had both our units replaced due to age. These guys took care of them quickly both times. They also responded quickly to service calls before the replacement. Friendly and trustworthy, I highly recommend!
