Why isn't my AC cooling? Common Shavano Park AC problems

If your AC is running but not cooling, blowing warm air, or won't turn on at all, you're not alone — these six failures account for most summer air conditioner repair calls in the 78231 area. We can usually finish the fix on the first visit.

AC blowing warm air

Usually a failed capacitor, low refrigerant, or a contactor that won't pull in. Diagnosed in under 20 minutes, fixed the same visit on most calls.

Outdoor unit not running

Capacitor (most common), contactor, or a tripped breaker. We carry universal capacitors and contactors on every truck — no second trip.

Frozen coil / water leaking

Dirty coil, low charge, or a clogged drain line. We thaw it, fix the root cause, and clear the line. Don't ignore it — frozen coils kill compressors.

Breaker tripping when AC starts

Shorted compressor, failing capacitor, or weak contactor. We test under load with clamp meters before swapping parts.

Thermostat blank or won't change temp

Dead batteries, blown 24V fuse on the air handler, or a tripped float switch. Often a 15-minute, low-cost fix.

Short-cycling (off after 1–2 min)

Overheating compressor, dirty condenser coil, or wrong refrigerant charge. We pull pressures plus superheat/subcool to find the actual cause.

Shavano Park AC repair — questions we get

How fast can you get to my AC in Shavano Park?

Same-day across Shavano Park — typically within 25 minutes from the time you call. We route by area, so once you book you'll usually get a tighter ETA within an hour. Mornings book first; on a hot afternoon emergency, call us directly (don't text) for the fastest answer.

What does AC repair cost in Shavano Park?

The diagnostic service call is free. The majority of Shavano Park repairs land between $185 and $895 — capacitors and contactors on the low end, fan motors and full refrigerant recharges higher up. Compressor replacements run $1,800–$3,400. You always get the written price before any work starts, and there's no surcharge for Shavano Park vs. inner San Antonio.

Which neighborhoods in Shavano Park do you cover?

All of them. We regularly run jobs across Shavano Park, NW Military corridor, Lockhill Selma area, and the rest of 78231. If you're inside the 78231 ZIP, you're in our zone.

Do you fix AC units on weekends in Shavano Park?

Yes. Saturdays and Sundays are normal service days for us at no overtime markup. Sundays after 6 PM and holidays carry a small after-hours fee, which we'll quote before we roll.

What brands of AC do you service in Shavano Park?

All major brands — Carrier, Trane, Goodman, Lennox, Rheem, York, Ruud, Amana, American Standard, Bryant, Payne. Our trucks carry universal capacitors, contactors, motors, and R-410A so most Shavano Park repairs finish on the first visit.

My AC is blowing warm — what should I do before you arrive?

Flip the thermostat to OFF (not just up to a higher temp), wait 10 minutes, then switch back to COOL. Check that the outdoor unit is running and not iced over. If the indoor coil is frozen, leaving the system OFF with the FAN ON for an hour or two lets it thaw — we can diagnose faster on a thawed system. Then call us and we'll roll.
