What people across Schertz say.
"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."
The Alvarez Family
Cibolo
"Hot bedrooms in our two-story Schertz 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."
Anthony M.
Cibolo
"Power flickered during a storm and the AC wouldn't turn on. Carnes replaced the surge-blown contactor and capacitor and installed a hard-wired surge protector on the disconnect. Smart preventive work."
Karen M.
Universal City
"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."
Carlos & Maria S.
Live Oak
"Coil was frozen, no cold air. Two other companies in Schertz 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."
Ray & Debbie A.
Universal City
"Evaporator coil was iced over and the house wouldn't get below 82°. Clint found a slow refrigerant leak at the line set, repaired it, and recharged the system. Other Schertz HVAC company had quoted a full AC replacement."
The Jenkins Family
Cibolo
"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."
Tara F.
Live Oak
"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."
Greg T.
Live Oak
"AC stopped cooling on a 102° Sunday. Called Carnes for AC repair, Clint was at our Cibolo house in under two hours. Capacitor was bad — replaced it on the spot. Two other companies in Schertz had told us we needed a whole new AC unit. We didn't."
Erin S.
Cibolo
"Thermostat was the actual problem, not the system. Other AC company in Schertz would've sold us a new control board. Carnes swapped the stat and we were done in 20 minutes."
Ben P.
Cibolo
"Cedar fever and oak pollen were destroying us in Schertz. Carnes upgraded our air filtration to a 4-inch MERV 11, sealed return-side leaks pulling attic dust in, and the difference was immediate."
Michelle G.
Universal City
"Got three quotes for AC replacement in Schertz. 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."
The Foster Family
Cibolo
"Carrier Factory Authorized Dealer matters because we got an extended warranty on top of Carrier's standard one. Other installers in Schertz couldn't offer that, even on the same equipment."
Zach & Laura E.
Universal City
"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."
Olivia P.
Universal City
"Our 22-year-old AC unit finally died. Clint walked us through HVAC replacement options without the high-pressure pitch. The Carrier system they installed runs quieter than the old one ever did and the CPS bill is noticeably lower."
Mike & Lisa T.
Live Oak
"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."
The Holloway Family
Live Oak
"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."
George W.
Universal City
"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."
Pete K.
Cibolo
"Condensate drain line was clogged and water was dripping through our ceiling in Universal City. Carnes cleared the AC drain line, flushed it, and installed a float switch so it can't flood the house again. Honest work."
The Whitfield Family
Universal City
"Outdoor unit was humming but the fan wasn't spinning. Turned out to be the run capacitor. Another HVAC company in Schertz had told my dad it was the compressor and quoted him a full system replacement. Carnes fixed it in twenty minutes."
The Patterson Family
Cibolo
"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."
Brian K.
Cibolo
"Moved to Schertz from out of state and had no idea who to call for HVAC service. Neighbor in Cibolo recommended Carnes. Now I recommend them to everyone on our street."
The Mendoza Family
Cibolo
"Builder-grade AC system in our Universal City 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."
Robert M.
Universal City
"I'm a single mom in Cibolo 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."
Gina B.
Cibolo
"Air conditioner drain line backed up and the system kept shutting off. Another Schertz 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."
Sarah P.
Universal City
"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."
