What people across Helotes say.
"Got three quotes for AC replacement in Helotes. 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."
Vanessa O.
Leon Valley
"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."
Kristin & Paul E.
Leon Valley
"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 Helotes HVAC company had quoted a full AC replacement."
The Alvarez Family
Alamo Ranch
"Our 1990s-era ductwork in Leon Valley 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."
Marcus B.
Leon Valley
"Two-story home in Leon Valley, 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."
Steve B.
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."
Zach & Laura E.
Alamo Ranch
"Carrier Factory Authorized Dealer matters because we got an extended warranty on top of Carrier's standard one. Other installers in Helotes couldn't offer that, even on the same equipment."
Pete K.
Alamo Ranch
"Coil was frozen, no cold air. Two other companies in Helotes 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."
Cody H.
Boerne
"Cedar fever and oak pollen were destroying us in Helotes. Carnes upgraded our air filtration to a 4-inch MERV 11, sealed return-side leaks pulling attic dust in, and the difference was immediate."
The Whitfield Family
Alamo Ranch
"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."
Tara F.
Alamo Ranch
"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."
Stephanie & Mark R.
Alamo Ranch
"Fan motor on the outdoor condenser seized in the middle of August. the tech had the part on the truck and we were back up the same afternoon. Other AC repair companies in Helotes were quoting two-week waits."
Jessica L.
Alamo Ranch
"AC was leaking water inside the house. Other guys said it was the evaporator coil and wanted to replace the whole indoor unit. Carnes diagnosed a clogged AC drain line, cleared it, done. Saved us thousands."
Erin S.
Leon Valley
"Hot bedrooms in our two-story Helotes home for years. Carnes did a proper duct assessment, found undersized returns and leaks at the plenum, and fixed it. We'd been told for years it 'just is what it is.' It wasn't."
Olivia P.
Alamo Ranch
"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."
Travis & Beth O.
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."
Ben P.
Boerne
"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."
The Mendoza Family
Boerne
"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."
Patricia H.
Boerne
"Air conditioner drain line backed up and the system kept shutting off. Another Helotes 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."
Nate G.
Boerne
"I'm a single mom in Alamo Ranch 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."
Danielle F.
Alamo Ranch
"Outdoor unit was humming but the fan wasn't spinning. Turned out to be the run capacitor. Another HVAC company in Helotes had told my dad it was the compressor and quoted him a full system replacement. Carnes fixed it in twenty minutes."
Brian K.
Boerne
"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."
Derek J.
Leon Valley
"AC stopped cooling on a 102° Sunday. Called Carnes for AC repair, Clint was at our Leon Valley house in under two hours. Capacitor was bad — replaced it on the spot. Two other companies in Helotes had told us we needed a whole new AC unit. We didn't."
The Castillo Family
Leon Valley
"Vacation home in Helotes sits empty most weekends. Their HVAC maintenance plan caught a slow refrigerant leak before we drove in to a hot house and a flooded ceiling."
Allison D.
Leon Valley
"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."
The Reyes Family
Boerne
"Moved to Helotes from out of state and had no idea who to call for HVAC service. Neighbor in Boerne recommended Carnes. Now I recommend them to everyone on our street."
