Boerne's grown a lot, but it still feels like a small town — and that's how we treat every customer out here. Whether you're on a ranch off 46, in Tapatio Springs, or in one of the new builds in Esperanza or Cibolo Canyons, I'll come out, look at your system, and give you a straight answer. A lot of my Boerne customers came from a neighbor's recommendation, and that's how I want to keep it. No high-pressure sales, no 'master tech' showing up two hours after the diagnostic to push a replacement.

From Boerne neighbors
What people across Boerne say.
"Evaporator coil was iced over and the house wouldn't get below 82°. the install crew found a slow refrigerant leak at the line set, repaired it, and recharged the system. Other Boerne HVAC company had quoted a full AC replacement."
Michelle G.
Spring Branch
"Carrier Factory Authorized Dealer matters because we got an extended warranty on top of Carrier's standard one. Other installers in Boerne couldn't offer that, even on the same equipment."
The Bradley Family
Helotes
"Three companies told us our compressor was shot. Clint pulled gauges, ran the numbers, and showed us it was just low on refrigerant from a slow leak. Repaired the leak, recharged, done. Compressor was fine. Still is."
Ray & Debbie A.
Helotes
"Blower motor in the attic gave out and the AC wouldn't push any air. Carnes diagnosed it, replaced the motor, and checked the static pressure on the ductwork while they were up there. Thorough work."
Sarah P.
Fair Oaks Ranch
"Our 1990s-era ductwork in Spring Branch had separated in three places in the attic. Carnes resealed the whole system — the next CPS bill was noticeably lower and the upstairs actually cools now."
The Holloway Family
Spring Branch
"Asked Clint about heat pump versus straight cool for our Boerne home. He spent twenty minutes on the phone walking through the trade-offs before I'd even scheduled. Didn't try to sell me up — just gave me the honest answer for our climate."
The Jenkins Family
Helotes
"Fan motor on the outdoor condenser seized in the middle of August. the install crew had the part on the truck and we were back up the same afternoon. Other AC repair companies in Boerne were quoting two-week waits."
Travis & Beth O.
Helotes
"AC wouldn't turn on at all on a Sunday afternoon. Carnes diagnosed a tripped float switch from a slowly clogging condensate line — cleared the line, reset the switch, no charge for the float. Other companies would've turned that into a service call plus a 'recommended' replacement."
Erin S.
Spring Branch
"AC stopped cooling on a 104° Tuesday. Called Carnes for AC repair, Clint was at our Helotes house in under two hours. Capacitor was bad — replaced it on the spot. Two other companies in Boerne had told us we needed a whole new AC unit. We didn't."
Tony & Rachel V.
Helotes
"Capacitor blew during a thunderstorm and the condenser wouldn't kick on. Carnes did the AC capacitor replacement the next morning and put a surge protector on the outdoor unit so it doesn't happen again."
Allison D.
Fair Oaks Ranch
"Other contractor refused to repair our AC and only quoted full replacement. Carnes came out, replaced the failed run capacitor and a worn contactor, and the system has been fine ever since. They actually fix things instead of selling new units."
Megan H.
Fair Oaks Ranch
"Got a second opinion after another big-name Boerne HVAC company told us we 'needed' a $14K replacement. Carnes found a stuck reversing valve and a low charge. Repaired both. System still running fine three years later."
Anthony M.
Fair Oaks Ranch
"Air conditioner drain line backed up and the system kept shutting off. Another Boerne HVAC company wanted to come out, charge a diagnostic, and reschedule the actual repair for the next week. Clint's tech cleared the clogged condensate drain line same day."
Vanessa O.
Spring Branch
"Coil was frozen, no cold air. Two other companies in Boerne said we needed a new AC unit. Carnes found a clogged filter and a low refrigerant charge from a tiny line set leak. Repaired and recharged. System has run two summers since with zero issues."
Doug L.
Fair Oaks Ranch
"Crew that did our Carrier install put booties on, laid drop cloths, and vacuumed the hallway when they were done. Hauled the old AC unit and copper off without us asking. Little things matter."
Linda C.
Fair Oaks Ranch
"Got three quotes for AC replacement in Boerne. Carnes wasn't the cheapest but the quote was the most detailed — exact Carrier model number, line set, thermostat, permit, everything itemized. Other guys had vague 'good/better/best' sheets designed to push the most expensive option."
George W.
Fair Oaks Ranch
"Builder-grade AC system in our Fair Oaks Ranch home was undersized from day one. Carnes did a proper load calculation and sized a Carrier 17 SEER for the actual square footage. House finally cools on triple-digit days."
Tommy D.
Fair Oaks Ranch
"Moved to Boerne from out of state and had no idea who to call for HVAC service. Neighbor in Spring Branch recommended Carnes. Now I recommend them to everyone on our street."
The Salinas Family
Spring Branch
"AC was running but not cooling. Clint found a dirty condenser coil packed with cottonwood and a slightly low refrigerant charge. Washed the coil, topped off, done. Whole house was cold within an hour."
The Reyes Family
Helotes
"Outdoor unit was humming but the fan wasn't spinning. Turned out to be the run capacitor. Another HVAC company in Boerne had told my dad it was the compressor and quoted him a full system replacement. Carnes fixed it in twenty minutes."
Pete K.
Spring Branch
"AC went out on a Saturday in Spring Branch. Carnes was out in two hours. No weekend surcharge, no out-of-town dispatcher, no 'master tech' showing up later to push a replacement. Just a real local AC repair company."
Wes C.
Spring Branch
"I'm a single mom in Helotes and I was bracing to get taken advantage of on AC repair. Clint just told me what was wrong, what it'd cost, and what I could put off until next year. No drama, no scare tactics."
Trevor R.
Helotes
"Annual AC tune-up caught a weak capacitor and a dirty condenser coil before they failed in July. Cheap insurance — exactly what HVAC maintenance is supposed to be. The other company we used to use just topped off refrigerant and called it a day."
Carlos & Maria S.
Spring Branch
"Heating quit on the coldest night of the year. Clint answered the phone himself at 9pm and had a tech at our Helotes house by 8am. Bad heat sequencer on the gas furnace. Quick repair, fair price."
Greg T.
Helotes
"Financing through Carnes was painless — $0 down, manageable monthly payment, brand-new Carrier system. Less than what we'd been spending on emergency AC repairs every summer."
Danielle F.
Fair Oaks Ranch
"Clean AC install. Tight line set, properly pitched condensate drain, labeled disconnects, breaker sized correctly, permit pulled, inspection passed first try. The kind of HVAC work you don't see anymore."
