San Antonio AC Repair, Heating And Plumbing Company

San Antonio AC Repair, Installation And Maintenance

Your air conditioner works harder in San Antonio than almost anywhere in the country. When it stops cooling, blows warm air, freezes up or starts making noises it shouldn’t, our technicians find the problem and fix it, usually the same day. Start with our AC repair in San Antonio.

The calls we take every week: AC not cooling, warm air from the vents, frozen coils, refrigerant leaks, bad capacitors and thermostats that won’t respond. If your older system keeps breaking down, our techs will give you a straight answer on repair versus replacement so you can decide with real numbers.

When it’s time to replace, we size and install new equipment that fits your home and your budget, with financing available. See our AC installation and replacement options. To keep a working system working, an AC maintenance tune-up catches small problems before they turn into an August breakdown.

We also install and service heat pumps, improve indoor air quality with filtration and purification, and handle duct installation, sealing and insulation plus residential duct cleaning, so the air you pay to cool actually reaches your rooms.

Heating Repair, Maintenance And Installation

San Antonio winters are short, but a cold snap with a dead heater makes for a long night. We handle heater repair, seasonal heater maintenance and furnace and heater replacement. Since we service both sides of your HVAC system, one company covers your heating and cooling all year.

Plumbing Repair And Water Heaters

From leaky faucets and low water pressure to failing garbage disposals, our plumbers handle plumbing repair in every room of the house, including kitchen and bathroom plumbing and gas line work. When old pipes keep failing, whole home repiping ends the cycle.

No hot water? We repair and replace water heaters and install tankless water heaters. For better water at every tap, we install water softeners and filtration systems, with salt delivery available for up to five years after installation. Businesses can count on us too for commercial plumbing.

San Antonio Drain Cleaning And Sewer Services

Drains are in our name. Our drain cleaning clears clogs in sinks, tubs, showers and main lines. Recurring clogs usually point to a bigger problem in the line, so we find the cause instead of just clearing the symptom. For tough blockages, we run sewer camera inspections to see what’s going on, then clear the line with hydrojetting or take care of sewer line repair. Same-day drain service is available across greater San Antonio.

Leak Detection And Slab Leak Repair

A small leak can do serious damage before you ever see it. We track down hidden leaks with professional leak detection and handle slab leak detection and repair under your foundation.

$20.26 HVAC Tune-Up

Book your 2026 HVAC tune-up for just $20.26 and catch small problems before they turn into big repairs. Request service to get on the schedule.
