About Alamo Comfort
Straight Answers, Not a Sales Pitch
We’re Alamo Comfort, the heating and cooling company San Antonio homeowners call when they want someone to tell them straight what’s wrong, not hand them an invoice for a whole new system and drive off. We repair, replace, and maintain every part of your HVAC system, through the 100° summers and the odd hard freeze alike.
Our rule is simple: fix what can be fixed, say so plainly when it can’t, and put the price in writing first. Most brands already warranty the parts. It’s the labor that catches people off guard, and that’s the part we take off your plate with our labor warranty of up to 10 years.

Complete HVAC services in San Antonio
Every System Your Home Runs On
Cooling, heating, air quality and light commercial. One honest team for all of it.
CoolingCooling Services
Your AC runs eight months a year here, and it never quits at a good time. Call us, and we'll find what's wrong: a worn part, a refrigerant leak, a clogged drain line, and show you what we found before we quote a price, and fix it right the first time. Need a new system? Rusty sizes it himself and backs the install with a labor warranty of up to ten years. We work on whatever brand you've got, and we put in what fits your home, not what pays us more. No commission, no pushing a unit you don't need.
What we handle
HeatingHeating Services
Our winters are short, but a furnace that's sat idle since spring won't warn you before it quits on the coldest night. We spot the problem, walk you through your options, and get the heat back on the same visit when we can. Replacing it? We size it to your home and put it in right, a good install beats a fancy unit installed wrong, every time.
What we handle
Air QualityIndoor Air Quality Services
Gulf humidity doesn't stay outside; it works its way into your home all summer, and your AC can only do so much. We measure the humidity and airflow first, then match the fix to your home. Whole-home dehumidifiers, better filters, UV light at the coil, equipment that treats the air where the system moves it, not plug-in gadgets, so every room feels it.
What we handle
CommercialCommercial
We also handle light commercial, offices, and small buildings, rooftop units, and maintenance contracts. Same straight answers and no-commission service our homeowners get, scaled for a business that can't afford downtime.

Licensed and Certified HVAC Contractor in San Antonio
Licensed and Certified: Here's What That Means
Every HVAC company in San Antonio says "licensed and insured." Here is what each credential is, and the specific way it protects you and your house.
State-Licensed & Insured
Texas requires a licensed contractor for all HVAC work, earned through testing, proven field experience, and maintained insurance. We hold ours and can show it.
Why it protects youThe work meets state code, so it won’t void your equipment warranty or fail an inspection at resale. If something goes wrong on the job, the liability sits with us, not with you or your homeowner’s insurance.
Legal to Handle Refrigerant
Federal law under the Clean Air Act makes it illegal to handle refrigerant without this certification, because mishandled refrigerant is both an environmental hazard and a system killer.
Why it protects youYour AC and heat pump are charged and serviced correctly. No leaks left sitting, no shortcuts that shorten system life. A correctly charged unit runs more efficiently and lasts longer.
The Alamo Comfort standard
We Don't Make Promises. We Do the Work.
Every HVAC company in town promises the world. We'd rather skip the promises, tell you what we do, and let the work back it up: clear numbers, no fine print, the same fair price for everyone.
"We've got New York-owned competitors. A lot of our competitors come in and just say, you just need a unit. We don't always do that."
Rusty Hoermann · Owner
Another company quotes a whole new system; we find the one worn part behind it. More often than not, you get a repair, not a replacement you never needed.
Nobody here earns a nickel more for selling you equipment. The advice you get is what your system needs, not what pads a sales sheet.
Every brand warranties the parts. The labor? Covered for up to ten years when we did the install.
The name on the truck is the name that answers. Decisions about your home get made here.
Rusty stays close to every install estimate. No commissioned closer between you and a straight answer.

Your AC Doesn't Clock Out. Neither Does Our Phone.
Break Down After Hours? Someone's Still Up.
When the cooling quits on a Saturday or the heat drops out on the coldest night, you won't get a voicemail and a “call us Monday.” You get a person, your details taken down, and a spot at the front of the line.
From your call to a technician
Our phone pulls the night shift; our trucks don't. Call at midnight and your no-cool July or no-heat freeze jumps to the top of the schedule, so you're first up when the workday clocks in, not stuck waiting till next week.
One call, and it's handled
Whether it's the middle of a July afternoon or the middle of the night, you've got one number to call and one team that answers for it. Save it now, the day your AC quits isn't the day to go shopping for who fixes it.
