What you get on an AC service call.
Same-day diagnostics
We track down the actual fault (capacitor, compressor, refrigerant leak, blower or board) and explain it in plain English before any work starts.
Up-front repair quotes
The diagnostic fee is disclosed before we drive out and rolled into the repair if you move forward. No surprise line items.
24/7 emergency calls
Condenser down at 9pm in August? We answer after-hours and prioritize no-cool emergencies for Houston-area homes.
All brands serviced
Trane, Carrier, Lennox, Goodman, Rheem, Ruud, American Standard, York and more. We service what we sell and what we'd run at home.
The calls we get every Houston summer.
AC blowing warm air
Usually low refrigerant, a failing compressor, or a tripped breaker. We pinpoint which before quoting a repair.
System won't turn on
Capacitor, contactor, thermostat, or float switch. We test the whole start sequence, not just the obvious part.
Frozen coil or water leaking
Restricted airflow and clogged condensate drains ice up coils and flood pans. We clear the cause, not just the symptom.
Short-cycling or loud noises
Rapid on/off and new rattles point to electrical, fan, or compressor trouble. Caught early, it's a far cheaper fix.
Everything else we keep running.
Heating & Furnace Repair
Heat that quits during a cold snap gets our attention fast. We work on gas, electric, heat-pump and dual-fuel systems from every major brand, Trane, Carrier, Lennox and Ruud included.
