HVAC, Start to Finish, Under One Roof in San Antonio, TX

Most San Antonio homeowners end up with a different company for every problem, one for the repair, another for the replacement, a third for the tune-up. We're Alamo Comfort Heating & Air Conditioning, the family-owned team that handles all of it from one place: cooling, heating, heat pumps, ductless systems, and indoor air quality, for homes across San Antonio and the Greater San Antonio Area.

We repair before we replace, put the price in writing first, and back our installs with a labor warranty of up to 10 years. We've been at it since 2014, we're licensed and owner-run, and Rusty still shows up to the work himself.

Air Conditioning Services

When your AC goes out in a San Antonio summer, you need someone who finds the actual fault, a worn capacitor, a refrigerant leak, a clogged drain line, not someone who hands you a quote for a whole new system the moment they pull up. We repair, install, and maintain central air conditioning across San Antonio and Bexar County. We show you what we found before we quote a number, and we fix it right the first time. If a replacement genuinely makes sense, Rusty sizes it himself and backs the install with a labor warranty of up to 10 years.

Heating Services

San Antonio winters are short, but a furnace that sat idle all summer won't warn you before it quits on the coldest night of the year. A system that short-cycles, blows lukewarm air, or won't kick on at all rarely needs replacing. It needs the right diagnosis. We repair, replace, and maintain furnaces and heating systems across the city, walk you through exactly what we found, and only bring up replacement when the numbers actually justify it. When they do, we size it to your home and put it in right, because a properly installed standard unit beats a premium unit installed wrong every time.

Indoor Air Quality Services

Comfort isn't just temperature; it's the air moving through your home and how it feels in every room. Gulf humidity works its way inside all summer, and your air conditioner can only do so much. Poorly designed or leaking ductwork leaves some rooms stuffy and others freezing, no matter where the thermostat sits. We measure humidity and airflow first, then match the fix to your home, equipment that treats the air where the system moves it, not plug-in gadgets that work in one corner of one room.

Commercial HVAC Services

San Antonio offices and small businesses can't afford a system that quits during a client meeting or a warehouse that bakes in August. We handle light commercial HVAC the same way we handle residential, written quote first, repair before replace, no-commission technicians who call it straight. Rusty runs every commercial estimate himself, and our maintenance contracts keep your system on a schedule before the emergency calls happen.
