HVAC & AC Repair
in Seguin, TX

Local HVAC Experts

Trusted HVAC contractor in Seguin, Texas

Seguin is the Guadalupe County seat, about 40 minutes east of our shop on I-10, with one of the oldest downtowns in Texas and a housing mix that runs from 1800s homes near the square to 1970s neighborhoods to brand-new subdivisions on the west side toward New Braunfels. Older homes need retrofit and duct redesign; newer builds need warranty-era repairs on builder-grade equipment. Seguin also has a growing manufacturing and commercial base along I-10 and SH 46 where we service rooftop units and warehouse ventilation. We are licensed and insured for both residential and commercial work here.

Every air conditioner, heat pump, gas furnace, and rooftop unit we service in Seguin is handled by a licensed Texas HVAC technician (TACLB80551C) — never a subcontractor. From quick AC repair calls and emergency heater diagnostics to full HVAC system replacement and routine seasonal maintenance, our family-run team treats every Seguin home like our own.

Common HVAC issues we see in Seguin homes

• Air conditioners short-cycling or freezing up during 100°F+ Seguin summer heat waves
• Low refrigerant, leaking evaporator coils, and failing capacitors on aging condensers
• Thermostat and control board failures after summer storms and power surges
• Clogged condensate drain lines causing water damage and ceiling stains
• Duct leaks, poor airflow, and uneven room-to-room cooling
