What people across Alamo Heights say.
"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."
Brian K.
San Antonio
"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."
Marcus B.
Shavano Park
"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."
Anthony M.
Shavano Park
"Carrier Factory Authorized Dealer matters because we got an extended warranty on top of Carrier's standard one. Other installers in Alamo Heights couldn't offer that, even on the same equipment."
The Reyes Family
San Antonio
"Got three quotes for AC replacement in Alamo Heights. 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 Patterson Family
San Antonio
"Hot bedrooms in our two-story Alamo Heights 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."
Amanda & David W.
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."
Sarah P.
Terrell Hills
"AC went out on a Saturday in Shavano Park. 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."
Derek J.
Shavano Park
"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."
Pete K.
Terrell Hills
"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."
The Mendoza Family
San Antonio
"Two-story home in San Antonio, 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."
Tara F.
San Antonio
"Got a second opinion after another big-name Alamo Heights 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."
George W.
Terrell Hills
"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 Alamo Heights HVAC company had quoted a full AC replacement."
Tommy D.
San Antonio
"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."
The Castillo Family
Terrell Hills
"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."
Robert M.
Shavano Park
"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."
Travis & Beth O.
Terrell Hills
"Cedar fever and oak pollen were destroying us in Alamo Heights. Carnes upgraded our air filtration to a 4-inch MERV 11, sealed return-side leaks pulling attic dust in, and the difference was immediate."
Patricia H.
Terrell Hills
"Fan motor on the outdoor condenser seized in the middle of August. Clint had the part on the truck and we were back up the same afternoon. Other AC repair companies in Alamo Heights were quoting two-week waits."
The Whitfield Family
Shavano Park
"Our 1990s-era ductwork in Shavano Park 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."
Olivia P.
Shavano Park
"Coil was frozen, no cold air. Two other companies in Alamo Heights 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."
Erin S.
Terrell Hills
"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."
Ben P.
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."
James R.
San Antonio
"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 Foster Family
Terrell Hills
"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."
The Nguyen Family
Shavano Park
"Outdoor unit was humming but the fan wasn't spinning. Turned out to be the run capacitor. Another HVAC company in Alamo Heights had told my dad it was the compressor and quoted him a full system replacement. Carnes fixed it in twenty minutes."
Kristin & Paul E.
San Antonio
"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."
