Why Choose Us
Heat and humidity push Carolina HVAC systems hard for most of the year, and cold snaps in January and February ask just as much of your furnace or heat pump. Without routine care, dust builds up on coils, filters clog, and small mechanical issues quietly turn into breakdowns. Preventive HVAC maintenance catches these problems while they're still small and inexpensive to fix, which is why steady HVAC system maintenance matters just as much as any single repair call.
At Keith Brown's Heating and Air Conditioning, we've worked as the local HVAC maintenance company for homes and businesses across Clover, Gastonia, Charlotte and the nearby towns for over 35 years. That experience means our technicians know how local humidity, pollen and seasonal temperature swings affect equipment differently than systems in drier climates. A properly maintained system runs quieter, uses less energy and lasts years longer than one that only gets attention when it fails.
Routine HVAC maintenance also protects your investment. Most manufacturer warranties require documented service, and skipping it can void coverage right when you need it most. Our HVAC maintenance plans keep clear records of every visit so you always have proof of care on file.

A little attention now saves a lot of trouble later. Homeowners and business owners across our service area call us for a maintenance visit when they notice any of the following:
Catching these signs early through a scheduled ac tune up or heating system tune up often means the difference between a simple adjustment and a full repair bill. If any of these sound familiar, it's a good time to have one of our technicians take a look.

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 !

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.

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.

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!

Don't wait for a breakdown to think about maintenance. A quick call now can keep your AC or furnace running smoothly through the season ahead, save you money on energy bills, and help you avoid an emergency repair down the road.
