AC Repair
From central air conditioning repair to condenser coil cleaning and refrigerant issues, we get your home or business cooling again quickly and correctly.

Fast, honest heating and cooling repair from a family business serving this area for over 35 years.
When your system stops working right, you need a fix you can trust.
Our Services
Heating and cooling systems in the Carolina Piedmont work hard. Between hot, humid summers around Gastonia and Charlotte and cold snaps that roll through Lincolnton and Shelby in the winter, your equipment rarely gets a break.
That constant demand means small issues turn into bigger, more expensive ones if they go unaddressed. A refrigerant leak, a worn-out capacitor, or a thermostat that's lost calibration can all quietly drive up your energy bills before a system fails completely.
Keith Brown's Heating and Air Conditioning has been diagnosing and repairing HVAC systems in this region since 1987. As a trusted HVAC repair contractor, our approach centers on real HVAC troubleshooting and HVAC system diagnostics that find the actual cause of a problem, not just patching the symptom, so the fix lasts.

Most heating and cooling problems give you warning signs before a full breakdown. Catching them early with prompt air conditioning repair or heating system repair keeps small issues from becoming costly ones, whether you need residential HVAC repair for your home or commercial HVAC repair for your business.
If any of this sounds familiar, it's a good time to call for air conditioning diagnostics or heating system troubleshooting before the next heat wave or cold front hits.
Our repair services
Whether it's your air conditioner, your furnace, or the thermostat that controls them both, our team handles the diagnostics and the fix. Below are the core repair services we offer to homeowners and business owners across Gastonia, Belmont, Charlotte, and the surrounding towns.

From central air conditioning repair to condenser coil cleaning and refrigerant issues, we get your home or business cooling again quickly and correctly.

Furnace repair, heater repair, and full heating system inspection services to keep your home warm through Carolina winters without a mid-January breakdown.

Thermostat troubleshooting, thermostat replacement, and hvac thermostat repair for systems that won't hold a setting or won't respond at all.
Our Process
We keep our repair process straightforward, because a stressful heating or cooling breakdown doesn't need extra confusion added to it. Here's how a typical service call works from start to finish.
Tell us what's happening with your system, from strange noises to warm air where cool air should be. We use those details to prepare for the visit and give you a realistic time frame.
Our technician inspects your equipment, checks electrical components, refrigerant levels, and airflow, and pinpoints the actual source of the problem rather than guessing at it.
We explain what's wrong in plain language, walk you through your repair options, and give you an upfront cost before any work begins on your home or commercial system.
Once you approve the work, we complete the repair, test the system to confirm it's running properly, and make sure you're comfortable again before we leave.

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!
