Pick the closest match. We’ll show you where it lives in your system, point you to the right fix, and pre-fill your service request. No twenty-question quiz.
From a 2 a.m. breakdown to a full Trane system, our licensed technicians handle every part of home comfort in San Antonio and the Hill Country.
When San Antonio heat pushes past 100°, you need cooling that performs every time. Blowing hot air, rattling, running up the bill — our technicians fix problems with precision and experience, not guesswork. Free estimates, so you understand your options before you commit.
Winters are mild, but when temperatures drop in San Antonio they drop fast — and without working heat, your home turns into a walk-in freezer. Electric, gas, or heat pump: our crew troubleshoots them all and installs modern systems built for performance and safety.
If your allergies get worse indoors, you're probably not wrong. Poor air quality is common in older homes and neglected systems. We clear the air — starting with free airflow testing.
Ducts are hidden, so nobody thinks about them — but they're one of the biggest reasons a home feels unevenly heated or cooled. Leaky ducts drain your wallet. Past 15 years old, an inspection often reveals more savings than you'd expect.
We're an authorized Trane dealer and Comfort Specialist — which means factory-trained installation of equipment engineered to survive South Texas. And because we service every major brand, you're never locked in.

A conventional system is a light switch with extra steps — the thermostat can say on or off, and that is the whole vocabulary. A communicating system holds a conversation. The ComfortLink™ II XL1050 and the equipment trade information continuously, so the system tunes itself to what is actually happening in your house instead of slamming to full power and shutting back off.
Cooling
Zones
Each zone reports its own temperature. The control damps airflow to the zones that are satisfied instead of over-cooling them.
Humidity
Target 40–50% in a San Antonio summer. Drag it up and watch the system run longer to pull the moisture out.
Runtime History
Seven days of run time. A properly sized system runs long and low, not short and hard.
System Info
With your approval, Diagnostics lets your dealer see this remotely — which is how a failing part gets caught before it quits.

TWO-WAY, CONTINUOUSLY — NOT ONE-WAY ON/OFF
On the card we leave on your table, this is the row that reads Communicating — see it on the card ↓
When a Cowboy sits down with you about a new system, this is what comes out of the folder. Five levels side by side — efficiency, staging, what each one actually includes — and every guarantee and warranty printed on the back. No mystery sheet, no “let me call my manager.” You keep the card.
Enlarge either side to read it exactly as printed. Which level fits your home depends on a load calculation — square footage, insulation, ductwork and windows — not on a number off a card.
Request an EstimateFourteen things we tell customers every week — every one of them traceable back to Trane's own engineering resources. The first four are the ones that actually matter in San Antonio.
An oversized system blasts cold, hits the setpoint and shuts off before it has pulled any moisture out of the air — leaving your house cold and clammy. The only honest way to size a system is a load calculation on your actual home.
SOURCE: TRANE ↗Water near the indoor unit, rust, or a musty smell when the AC runs means the condensate line is plugging up. San Antonio humidity makes far more condensate than most of the country, and hard water speeds up the scale.
SOURCE: TRANE ↗The EPA range is 30–50%, with 30–40% ideal in summer. Above 60% you get mold, dust mites, warped floors and worse asthma — and down here your AC alone may not keep up with it.
SOURCE: TRANE ↗A typical home loses 20–30% of its conditioned air to duct leaks. In a 140° Texas attic that isn't just loss — it's pulling scorching, dusty, unfiltered air into the house.
SOURCE: TRANE ↗Trane's window is every 3 to 9 months depending on the unit. Our dust and cedar pollen push you toward the short end of that, not the long end. Check your manual for the exact interval.
SOURCE: TRANE ↗A denser filter catches more, but it also restricts airflow — the biggest number on the shelf isn't automatically the right one. And the arrow on the filter has to point toward the furnace or air handler.
SOURCE: TRANE ↗SEER2 replaced SEER in 2023 with a tougher test that reflects real duct pressure. Texas falls under the stricter Southern floor: 14.3+ under 45,000 BTU, 13.8+ above it.
SOURCE: TRANE ↗Keep plants and landscaping two feet back on every side and aim mower discharge away from it. Dirty coils make the system work harder. Garden hose only — a pressure washer bends the fins.
SOURCE: TRANE ↗Every degree above 72° saves up to about 3% on cooling, but 78 is outside a lot of people's comfort zone. Nudge up a degree at a time and lean on fans, blinds and dehumidification to make it feel fine.
SOURCE: TRANE ↗One professional visit a year, scheduled in spring before the season turns. With a cooling season as long as ours, a pre-season tune-up here is closer to mandatory than optional.
SOURCE: TRANE ↗A 7–10 degree setback for eight hours a day cuts heating and cooling costs about 10% a year. Just don't set back so far that humidity climbs while you're out.
SOURCE: TRANE ↗It feels thrifty and it isn't. The system needs at least 75% of your vents open to move air correctly — closing them off unbalances everything and makes the unit work harder.
SOURCE: TRANE ↗Returns pull air back to the equipment to restart the cycle, so blocking one throws off pressure across the whole system. Keep furniture, rugs and drapes off them.
SOURCE: TRANE ↗R-454B has a global warming potential more than 75% lower than R-410A, and the transition started in 2024. Here's the part nobody tells you: your existing R-410A system can still be serviced.

★★★★★"Our AC died at 11 PM on a Saturday in July. Cowboys had a tech at our house by midnight and we had cold air by 12:30 AM."
★★★★★"Showed up on time, explained exactly what was wrong in plain English, and had it fixed within an hour. No upselling, no pressure."
★★★★★"Fixed a capacitor nobody else could figure out. Third company we called — two hours, done. Honest and fast."
Dispatched from Blanco Road, covering six counties around San Antonio. If you're on the map, you're in range.
It could be airflow, a dirty filter, low refrigerant, the outdoor unit, frozen coils, a thermostat issue, or a failing component. Because San Antonio heat puts heavy demand on cooling systems, it's best to schedule service before the problem gets worse — we'll identify the cause and recommend the right repair.
A healthy system cools about 15–20° below the outdoor temperature. In peak San Antonio heat it may run longer, but it should still produce cold air and pull humidity. If it feels weak or warm, have it checked.
Yes — holidays, weekends, the middle of the night. If the weather doesn't wait, neither do we. Call (210) 495-7771 any time.
Yes — we're an authorized Trane dealer and Comfort Specialist, and we service every major brand, so you're never locked in.
Your system should have a brief delay before restarting after it shuts off — this protects the compressor and prevents unnecessary wear. Most modern thermostats manage it automatically. Frequent on/off cycling can signal short cycling or another issue worth inspecting.
Poor airflow is one of the most common — it makes rooms feel unevenly heated and lowers efficiency. If your furnace isn't heating properly, cycles too often, or makes unusual noises, we can get it working safely and reliably.
