Cool air back on today in Seguin
Seguin's older brick homes (many from the 60s-80s) almost always have undersized return ducts, which is why we see the same coils freezing year after year out here. We fix the airflow problem, not just recharge the system.

No call center routing you in circles, no commission salesperson upselling a new system you don't need. Just a straight answer, a fair price, and your house comfortable again before bedtime.
Why isn't my AC cooling? Common Seguin 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 78155 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.

What Your Neighbors Are Saying
Seguin neighborhoods we serve
Seguin AC repair — questions we get
How fast can you get to my AC in Seguin?
Same-day across Seguin — typically within 60 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 Seguin?
The diagnostic service call is free. The majority of Seguin 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 Seguin vs. inner San Antonio.
Which neighborhoods in Seguin do you cover?
All of them. We regularly run jobs across Mill Creek, Navarro, Geronimo, Starcke Park area, and the rest of 78155. If you're inside the 78155 ZIP, you're in our zone.
Do you fix AC units on weekends in Seguin?
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 Seguin?
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 Seguin 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.
