Your AC quit on the hottest day of the year. We've been fixing that exact problem for San Antonio homeowners for over 24 years — same-day, all brands, upfront pricing.

Schedule AC Repair Call (210) 561-COOL

San Antonio runs its air conditioning harder than almost any city in the country. Our cooling season starts in March and doesn't let up until November — that's 8 months of near-constant use. Your system cycles thousands of times a year, and every component in it is working against heat, humidity, and dust. Things break. The question isn't if, it's when.

We've been repairing AC systems across San Antonio for over 24 years. We've seen the same failures repeat across the same neighborhoods, the same builders, the same vintages of equipment. Homes near Lackland and Randolph tend to have older builder-grade systems that need capacitors every few years. Older homes in Alamo Heights and Terrell Hills often have undersized ductwork that strains the equipment. Stone Oak and new construction in Cibolo tend toward refrigerant issues from installation shortcuts. That pattern recognition is what lets us diagnose faster and fix it right the first time — not guess, not swap parts until something works.

We service every major brand — Trane, Carrier, Lennox, Rheem, Goodman, York, Amana, and everything in between. If it cools a house in San Antonio, we've worked on it. We carry the most common repair parts on our trucks so most jobs are completed in a single visit without a second trip to the supply house.

Why Choose Our AC Repair Service

Same-day service available — most repairs completed in one visit. When it's 105° outside, you don't have time to wait until next week.

All brands and models serviced. We're a Trane Comfort Specialist, but we repair every major manufacturer. We don't turn away non-Trane systems.

Upfront pricing before any work starts. You approve the cost, or we don't touch it. No "well, while we were in there..." surprises on your bill.

Licensed, insured, EPA-certified technicians. Not a subcontracted crew — our own techs who've been doing this for years and know San Antonio homes.

1-year warranty on all repairs. If the same part fails within 12 months, we come back and fix it at no charge.

Open 7 days a week including holidays. AC doesn't pick convenient times to fail, and neither do we.

AC Problems We See Every Week in San Antonio

These aren't hypothetical scenarios — they're the calls we run most often, especially between May and September when every system in the city is working at full capacity. If you're experiencing any of these, don't wait. Most of these get worse (and more expensive) the longer the system runs with a problem.

Capacitor Burnout

The most common summer failure. Capacitors start your compressor and fan motors — when they blow, your system hums but doesn't actually cool. Texas heat accelerates capacitor wear. We carry the most common sizes on our trucks for same-visit replacement. Typical cost: $300–$450.

Refrigerant Leaks

If your system blows air but it's not cold, you might have a refrigerant leak. We locate the leak, repair it, and recharge the system. Just topping off refrigerant without fixing the leak is a waste of money — the gas escapes again within weeks. We see this constantly from competitors' previous "repairs."

Frozen Evaporator Coil

Your indoor coil ices over and airflow drops to nothing. Usually caused by low refrigerant, a failing blower motor, or a clogged filter that restricted airflow too long. We thaw the coil, fix the root cause, and check for secondary damage.

Contactor Failure

The contactor is an electrical switch that turns your compressor on and off. When it welds shut or burns out, your system either runs nonstop or won't start at all. Common in systems over 8 years old. Quick fix when caught early — expensive compressor damage if ignored.

Condensate Drain Clogs

San Antonio humidity means your AC pulls gallons of water out of the air daily. That water drains through a PVC line that algae and dust love to clog. When it backs up, you get water damage in your attic or a safety switch that shuts down the whole system. We clear the line and treat it to prevent regrowth.

Compressor Failure

The most expensive AC repair. Compressors fail from electrical damage, refrigerant issues, or age. A compressor replacement runs $1,200–$2,500 depending on the system. If your system is over 12 years old and the compressor fails, we'll give you an honest comparison of repair vs. replacement costs.

What to Expect

You call, we schedule — usually same-day. If your system is completely down in summer, we prioritize you. We give you a 2-hour arrival window, not a vague "sometime between 8 and 5."

Our technician arrives, introduces himself, and asks what you've noticed. Strange noises, warm air, water leaks, high bills — every detail helps narrow it down before we open a panel.

Full system diagnostic: we check electrical readings, refrigerant pressures, airflow, thermostat calibration, and component condition. We're not looking for one problem — we're looking for everything that's wrong or about to be.

We explain what we found in plain English. Not technical jargon, not scare tactics. Here's what broke, here's why, here's what it costs to fix. You approve the price before we pick up a wrench.

We complete the repair using quality parts — not the cheapest thing from a supply house. We test the entire system under load to make sure it's not just running, but running right.

Before we leave, we walk you through what happened and what to watch for. If there's a maintenance issue that contributed to the failure, we'll tell you — not to upsell you, but because a $89 tune-up is cheaper than another $600 repair next summer.

AC repair typically costs $300–$800 in San Antonio.

Diagnostic fee of $89–$250 is applied toward the repair if you move forward the same day. No hidden fees.

Frequently Asked Questions

Most AC repairs run between $300 and $800. A capacitor or contactor replacement is on the low end ($300–$450). Refrigerant leak repair and recharge lands in the middle ($500–$700). A compressor replacement is the most expensive common repair at $1,200–$2,500. We charge a diagnostic fee of $89–$250 that gets applied to the repair total if you move forward the same day.

We offer same-day service for most AC repair calls, with a 2-hour arrival window. During peak summer months (June–August), demand is highest and we triage by severity — a complete system failure in a home with elderly residents or small children gets priority. We're open 7 days a week including holidays. After-hours and emergency calls carry a surcharge of $134–$200 on top of the repair cost, but when your house is 95° at midnight, that's a reasonable price for getting someone there.

The three most common causes: low refrigerant from a leak, a failed compressor, or a frozen evaporator coil. Less common but possible: a stuck reversing valve (heat pump systems), a failed run capacitor, or a blocked condenser coil. First thing to check yourself: look at your air filter. If it's solid gray or hasn't been changed in 3+ months, swap it and give the system 30 minutes. A clogged filter causes about 20% of the "not cooling" calls we get. If the filter is fine, go outside and look at your condenser — if the fan isn't spinning, that's likely a capacitor or contactor. Don't keep running the system if it's blowing warm — you can cause compressor damage. Turn it off and call us.

Our rule of thumb: if the repair costs more than half what a new system costs, and your unit is over 10 years old, replacement usually wins. A $600 repair on a 15-year-old system is buying you another year or two, not solving the underlying problem. Also consider your energy bills — a system from 2010 might be running at 10 SEER while a new system is 15-16 SEER2. In San Antonio, where your AC runs most of the year, that efficiency difference can save $50–$80/month on your CPS Energy bill. We'll show you the numbers for both options and let you decide — we don't push replacements when a repair will genuinely last.

Yes. We're a Trane Comfort Specialist dealer, but our technicians are trained on every major brand: Carrier, Lennox, Rheem, Goodman, York, Amana, Daikin, Mitsubishi, and more. The diagnostic process is the same regardless of brand — electrical, refrigerant, airflow, and mechanical. Where brand matters is parts: some manufacturers make proprietary control boards or coils that need to be ordered from the distributor, which can add a day or two for uncommon systems. But for the most common repairs — capacitors, contactors, fan motors, refrigerant — we carry universal and OEM parts on every truck. If it cools a house in San Antonio, we can fix it.

Buzzing usually points to an electrical issue — a failing contactor or relay. Clicking at startup can be a bad capacitor trying to fire. Grinding or screeching means a motor bearing is going out — the fan motor in your air handler or the condenser fan motor outside. Hissing suggests a refrigerant leak at a braze joint or Schrader valve. Banging from the outdoor unit often means a loose or broken compressor mount, or sometimes a stick or debris that fell into the condenser fan. A high-pitched whine from the indoor unit can be a blower wheel that's come loose on its shaft. None of these get better on their own. The longer you wait, the more likely a cheap fix turns into an expensive one. A $200 fan motor becomes a $2,000 compressor when the system overheats.

If another company quoted you a major repair — especially a compressor replacement or full coil swap — a second opinion is smart. We see cases where the actual problem was a $300 part but the first company quoted $2,000. We don't charge extra for being the second call, and our diagnostic fee still applies toward the repair.

You can't prevent every failure, but annual maintenance catches most problems before they strand you in the heat. The biggest thing you can do yourself: change your filter every 30–60 days during summer. A clogged filter restricts airflow, freezes your coil, and stresses every component in the system. Use a basic pleated filter — those expensive HEPA filters actually restrict airflow too much for most residential systems and can cause the same problems as a dirty filter. Beyond that, a professional tune-up in spring ($89–$250) checks refrigerant levels, electrical connections, and the condensate drain — the three things that cause 80% of summer breakdowns. Keep your outdoor condenser clear of debris and trim vegetation back 2 feet on all sides so it can breathe. And if you hear anything new — clicking, buzzing, grinding — call sooner rather than later. Small noises become big invoices.
