This city raised my family. I've been fixing AC units across San Antonio since '96 — from Medical Center condos to Southside ranches, from 1920s Monte Vista bungalows to brand-new builds out 1604. I've seen what 105-degree summers do to every kind of system in this town. If yours is acting up, just call me. I'll tell you exactly what's going on and what it'll cost before we touch anything — no upsell, no scare tactics, no 'master tech' showing up to push a $15K replacement on a $400 fix.

What people across San Antonio say.
"AC was running but not cooling. the tech 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."
Jessica L.
Leon Valley
"Our 1990s-era ductwork in Terrell Hills 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."
Robert M.
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."
Drew & Kim L.
Alamo Heights
"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."
Gina B.
Alamo Heights
"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."
Tara F.
Alamo Heights
"Hot bedrooms in our two-story San Antonio 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."
Jordan & Casey N.
Terrell Hills
"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."
Amanda & David W.
Alamo Heights
"Outdoor unit was humming but the fan wasn't spinning. Turned out to be the run capacitor. Another HVAC company in San Antonio had told my dad it was the compressor and quoted him a full system replacement. Carnes fixed it in twenty minutes."
The Reyes Family
Alamo Heights
"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."
Bryan W.
Terrell Hills
"AC stopped cooling on a 104° Tuesday. Called Carnes for AC repair, Clint was at our Terrell Hills house in under two hours. Capacitor was bad — replaced it on the spot. Two other companies in San Antonio had told us we needed a whole new AC unit. We didn't."
The Salinas Family
Terrell Hills
"Air conditioner drain line backed up and the system kept shutting off. Another San Antonio 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."
Olivia P.
Terrell Hills
"Coil was frozen, no cold air. Two other companies in San Antonio 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."
Trevor R.
Terrell Hills
"Carrier Factory Authorized Dealer matters because we got an extended warranty on top of Carrier's standard one. Other installers in San Antonio couldn't offer that, even on the same equipment."
The Alvarez Family
Leon Valley
"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."
Tommy D.
Alamo Heights
"Builder-grade AC system in our Alamo Heights 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.
Alamo Heights
"Condensate drain line was clogged and water was dripping through our ceiling in Leon Valley. Carnes cleared the AC drain line, flushed it, and installed a float switch so it can't flood the house again. Honest work."
Cody H.
Leon Valley
"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 San Antonio were quoting two-week waits."
Tony & Rachel V.
Leon Valley
"Our 20-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."
James R.
Terrell Hills
"Heating quit on the coldest night of the year. Clint answered the phone himself at 9pm and had a tech at our Alamo Heights house by 8am. Bad heat sequencer on the gas furnace. Quick repair, fair price."
Holly J.
Alamo Heights
"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 Patterson Family
Leon Valley
"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 Jenkins Family
Leon Valley
"AC went out on a Saturday in Alamo Heights. 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."
The Holloway Family
Alamo Heights
"Got a second opinion after another big-name San Antonio 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."
Allison D.
Terrell Hills
"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."
The Nguyen Family
Terrell Hills
"Asked Clint about heat pump versus straight cool for our San Antonio 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."
Brian K.
Alamo Heights
"Got three quotes for AC replacement in San Antonio. 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."
