AC repair & replacement
in The Dominion.

"Our older AC unit ran on R-22 and was low on refrigerant. Carnes was honest — said they could top it off but at our system's age the smarter move was a new R-410A Carrier. No pressure either way. We chose the AC replacement and the Carrier financing made it doable."

"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."

Olivia P.

"Two-story home in Shavano Park, upstairs would never get below 80°. Other AC company quoted us a second system. Carnes added a return, sealed leaky ducts, and balanced the airflow. Fixed for a fraction of what the second-system quote would have been."

Trevor R.

Shavano Park

"Big-name AC company in San Antonio quoted us almost double what Carnes charged for the same Carrier system, same tonnage, same SEER rating. Read the quotes side by side — identical equipment, wildly different prices."

"Allergies were brutal this spring. Clint installed a 5-inch MERV 13 media filter cabinet and cleaned the evaporator coil. Wife stopped waking up congested within a week. Real air filtration, not the 1" cardboard filter the builder put in."

Travis & Beth O.

Helotes

"What sold me was that Clint answered his own phone. No call center, no runaround. Just a guy who knows AC and gives you a straight answer about repair versus replacement."

Steve B.

Leon Valley

"Contactor was pitted and the AC wouldn't kick on. Quick repair from Carnes — they showed me the burned contacts so I'd know what they were charging me for. No upsell to a full HVAC replacement like the last company tried."

The Patterson Family

Leon Valley

"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."

The Mendoza Family

Shavano Park

"Moved to The Dominion from out of state and had no idea who to call for HVAC service. Neighbor in Shavano Park recommended Carnes. Now I recommend them to everyone on our street."

Megan H.

Shavano Park

"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 The Dominion HVAC company had quoted a full AC replacement."

Kristin & Paul E.

Helotes

"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."

Erin S.

Leon Valley

"Builder-grade AC system in our Shavano Park 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."

Patricia H.

Shavano Park

"Outdoor unit was humming but the fan wasn't spinning. Turned out to be the run capacitor. Another HVAC company in The Dominion had told my dad it was the compressor and quoted him a full system replacement. Carnes fixed it in twenty minutes."

Jordan & Casey N.

Helotes

"AC stopped cooling on a Saturday in July. Called Carnes for AC repair, the install crew was at our Leon Valley house in under two hours. Capacitor was bad — replaced it on the spot. Two other companies in The Dominion had told us we needed a whole new AC unit. We didn't."

Drew & Kim L.

Leon Valley

"AC was running but not cooling. their guy 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."

Holly J.

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."

The Jenkins Family

Shavano Park

"AC wouldn't turn on at all on a Saturday in July. 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."

Pete K.

Leon Valley

"Coil was frozen, no cold air. Two other companies in The Dominion 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."

The Nguyen Family

Helotes

"I'm a single mom in Leon Valley 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."

The Whitfield Family

Leon Valley

"Signed up for the maintenance plan after Carnes did our AC service. Two visits a year, cleaned coils, checked refrigerant pressures, tightened electrical. Caught a contactor going bad before it left us without AC."

Wes C.

Helotes

"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."

Danielle F.

Helotes

"Got three quotes for AC replacement in The Dominion. 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."

Tony & Rachel V.

Shavano Park

"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."

Nate G.

Helotes

"Condensate drain line was clogged and water was dripping through our ceiling in Shavano Park. Carnes cleared the AC drain line, flushed it, and installed a float switch so it can't flood the house again. Honest work."

Linda C.

Shavano Park

"Cedar fever and oak pollen were destroying us in The Dominion. Carnes upgraded our air filtration to a 4-inch MERV 11, sealed return-side leaks pulling attic dust in, and the difference was immediate."

Frank T.

Shavano Park

"Thermostat was the actual problem, not the system. Other AC company in The Dominion would've sold us a new control board. Carnes swapped the stat and we were done in 20 minutes."
