From Alamo Ranch neighbors
What people across Alamo Ranch say.
"Builder-grade AC system in our Leon Valley 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."
Frank T.
Leon Valley
"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."
Derek J.
Leon Valley
"Cedar fever and oak pollen were destroying us in Alamo Ranch. 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 Jenkins Family
Helotes
"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."
The Reyes Family
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 Alamo Ranch were quoting two-week waits."
Nate G.
San Antonio
"Air conditioner drain line backed up and the system kept shutting off. Another Alamo 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."
Heather A.
San Antonio
"Outdoor unit was humming but the fan wasn't spinning. Turned out to be the run capacitor. Another HVAC company in Alamo Ranch had told my dad it was the compressor and quoted him a full system replacement. Carnes fixed it in twenty minutes."
Vanessa O.
Helotes
"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."
Trevor R.
Helotes
"Evaporator coil was iced over and the house wouldn't get below 82°. the tech found a slow refrigerant leak at the line set, repaired it, and recharged the system. Other Alamo Ranch HVAC company had quoted a full AC replacement."
Bryan W.
Leon Valley
"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."
Cody H.
Leon Valley
"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."
The Mendoza Family
Helotes
"Vacation home in Alamo 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."
George W.
Leon Valley
"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."
Pete K.
San Antonio
"Coil was frozen, no cold air. Two other companies in Alamo Ranch 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."
Jessica L.
Helotes
"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."
Olivia P.
Leon Valley
"Hot bedrooms in our two-story Alamo 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."
Linda C.
Helotes
"Thermostat was the actual problem, not the system. Other AC company in Alamo Ranch would've sold us a new control board. Carnes swapped the stat and we were done in 20 minutes."
The Nguyen Family
San Antonio
"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."
The Holloway Family
Leon Valley
"Our 1990s-era ductwork in Helotes 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."
Drew & Kim L.
Helotes
"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.
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."
Michelle G.
Leon Valley
"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."
Steve B.
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."
The Patterson Family
Leon Valley
"Got three quotes for AC replacement in Alamo 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."
Nicole R.
Leon Valley
"Moved to Alamo Ranch from out of state and had no idea who to call for HVAC service. Neighbor in Helotes recommended Carnes. Now I recommend them to everyone on our street."
Travis & Beth O.
Helotes
"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."
