Expert HVAC Repair in McKinney, TX
Your system stopped cooling — or stopped heating — and you need it fixed today, not next week. Texas 1st Choice Heat & Air provides same-day HVAC repair for McKinney homeowners, with licensed technicians who diagnose the real problem first and fix it right the first time.
Signs Your HVAC System Needs Professional Repair
A failing HVAC system rarely gives you one clean warning sign — it gives you several. The unit runs but your home never reaches the temperature on the thermostat. You hear sounds you haven't heard before: rattling from the air handler, clicking from the outdoor unit, or a hiss near the refrigerant lines. Your energy bill climbs even though your usage hasn't changed. In Texas, a system struggling in July heat or a January cold snap puts real stress on your home — the longer a failing component runs, the more strain it places on the parts around it.
- AC or heat is running but temperatures aren't changing
- Warm air from supply vents when cooling is set
- System short-cycles — turns on and off repeatedly
- Unusual sounds: rattling, banging, clicking, or hissing
- Energy bills rising with no change in usage
- Ice buildup on evaporator coil or refrigerant lines
- System won't turn on at all — thermostat unresponsive
What Our HVAC Repair Service in McKinney Includes
Not every HVAC company approaches a repair call the same way. At Texas 1st Choice Heat & Air, every repair starts with a systematic diagnosis — not a guess, not a parts swap, and not a sales pitch for a new system. Our licensed technicians work through your system methodically: thermostat and controls first, then the air handler or furnace, then the outdoor unit. The symptom you're experiencing is often caused by something upstream from where you'd expect.
Cooling System Repairs
Capacitors, contactors, condenser fan motors, blower motors, refrigerant leak detection and repair, evaporator and condenser coil service, and full electrical diagnostics. We test with manifold gauges and digital multimeters before recommending any part.
Heating System Repairs
Furnace ignition components, gas valves, flame sensors, inducer motors, control boards, heat pump reversing valves, and defrost controls. Combustion safety is checked on every gas appliance call.
Airflow & Thermostat Repair
Blower assemblies, duct leak inspection, return-air restrictions, condensate line clearing, smart and conventional thermostat replacement or calibration.
Once we've identified the actual cause, you receive a clear, upfront quote. You decide what work to authorize — and your service call fee is credited back toward the cost of the repair when you move forward.
