AC repair & replacement
in Fair Oaks Ranch.

"Air conditioner drain line backed up and the system kept shutting off. Another Fair Oaks Ranch 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."

"Hot bedrooms in our two-story Fair Oaks Ranch 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."

Wes C.

"Vacation home in Fair Oaks Ranch 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."

"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."

Marcus B.

Shavano Park

"Got three quotes for AC replacement in Fair Oaks Ranch. 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."

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

Robert M.

"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."

Heather A.

Helotes

"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 Fair Oaks Ranch were quoting two-week waits."

Linda C.

Helotes

"AC wouldn't turn on at all on a 102° Sunday. 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."

Anthony M.

Helotes

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

The Jenkins Family

Boerne

"Evaporator coil was iced over and the house wouldn't get below 82°. their guy found a slow refrigerant leak at the line set, repaired it, and recharged the system. Other Fair Oaks Ranch HVAC company had quoted a full AC replacement."

Steve B.

Shavano Park

"Builder-grade AC system in our Boerne 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."

Jessica L.

Boerne

"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."

George W.

Helotes

"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."

Danielle F.

Boerne

"Our 16-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."

The Garcia Family

Boerne

"Two-story home in Helotes, 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."

Karen M.

Helotes

"Carrier Factory Authorized Dealer matters because we got an extended warranty on top of Carrier's standard one. Other installers in Fair Oaks Ranch couldn't offer that, even on the same equipment."

Brian K.

Helotes

"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."

Tommy D.

Shavano Park

"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.

Boerne

"Other contractor refused to repair our AC and only quoted full replacement. Carnes came out, replaced the failed run capacitor and a worn contactor, and the system has been fine ever since. They actually fix things instead of selling new units."

Pete K.

Boerne

"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."

Derek J.

Helotes

"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."

James R.

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."

The Whitfield Family

Helotes

"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."

The Foster Family

Helotes

"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."

Patricia H.

Helotes

"I'm a single mom in Shavano Park 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."
