Mobile Auto AC & Heating Repair in Leon Valley, TX

AC Not Cooling in Leon Valley? We Come to You

Leon Valley (78238) summers are among the hottest in Texas — interior temperatures in a parked car can exceed 140°F within minutes. When your AC blows warm air on Bandera Road in Leon Valley, it's not just uncomfortable: heat exhaustion is a real risk for kids, pets, and anyone with health conditions. We come to your home or workplace in Leon Valley to diagnose and repair your auto AC system on-site. The working vehicles, trucks, and sedans common in Leon Valley each have different refrigerant specifications and AC system layouts — we confirm the correct approach before arriving.

What We Diagnose and Repair On-Site

Our AC service includes manifold gauge testing (high and low-side pressure readings at multiple RPM ranges), electronic leak detection, dye injection and UV leak tracking for slow leaks, refrigerant recovery and recharge with the correct refrigerant type (R-134a or R-1234yf depending on your vehicle year), and electrical testing of the compressor clutch, pressure switches, and blower motor. The most common repairs: refrigerant recharge ($149+), O-ring and seal replacement ($200–$350), expansion valve replacement ($275+), and compressor replacement ($850+). We don't guess-recharge — we diagnose the actual failure first.

Heating Problems — Not Just an AC Issue

Cold air that blows when you switch to heat is a heater core or coolant flow issue, not an AC problem. We diagnose and repair both systems: blend door actuators (common in Ford and GM vehicles), heater core leaks (coolant smell inside cabin, fogged windshield), and thermostat failures that prevent the engine from reaching operating temperature. Heating diagnosis is $95, credited toward repair if we proceed at the same visit.
