Keith Brown's Heating and Air Conditioning provides trusted HVAC maintenance and repair in Belmont, NC, keeping homes and businesses comfortable with honest AC repair, heating repair, and preventative HVAC maintenance.
Our family-owned team has served Belmont for decades.
Belmont sits close enough to the Catawba River and Lake Wylie that summer humidity settles in fast and stays late into September, which means air conditioners around Stowe Park, Eagle Mill Village, and the neighborhoods off South Point Road work overtime for months at a time. Homes near Daniel Stowe Botanical Garden and the historic downtown district often deal with older ductwork or units that were sized for a different era, and that combination of age and heavy seasonal use is exactly where small problems turn into breakdowns.
Winters here aren't brutal, but the swing from warm days to cold nights puts real stress on furnaces and heat pumps, especially in the older mill houses closer to Main Street. A system that's been ignored all year tends to fail on the coldest morning of the season, not the mildest one.
That's why we focus on keeping systems maintained year round, not just fixing them once they break. Our technicians know the housing stock in Belmont, from newer builds near Belmont Abbey College to the classic bungalows downtown, and we bring that local knowledge to every repair and maintenance visit.

Common issues we see in Belmont
Belmont's mix of established neighborhoods and newer developments means we see a wide range of HVAC problems, from aging condenser coils to thermostats that just won't hold a setting. Regular AC preventative maintenance and heating maintenance catch most of these issues before they become emergency calls.
Here's what tends to send Belmont residents looking for repair or maintenance:

Belmont HVAC questions
Here are a few questions we hear often from homeowners and business owners around Belmont.
Given how long and humid Belmont summers run, we recommend an AC tune up each spring before the heavy cooling season starts. Homes near the river corridors or with older units may benefit from a mid-summer check as well.
Yes. We provide commercial AC repair and commercial HVAC maintenance for business properties throughout Belmont, from small storefronts near Main Street to larger commercial buildings.
Sometimes. Thermostat troubleshooting can reveal wiring issues, sensor failures, or signs that the connected system itself needs attention. We check the full setup during a thermostat repair visit, not just the thermostat itself.

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.

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!
