When desert winter nights plummet into the 20s, a broken heater is an emergency. Our licensed technicians provide 24/7 furnace troubleshooting, hot surface igniter replacements, carbon monoxide testing, and rapid repair across Lancaster.
High-desert thermal swings stress furnace ignition cycles. Here are the most common failures our Lancaster trucks fix on-site:
Silicon carbide igniters become brittle and crack with age, preventing gas burner ignition. We stock universal silicon nitride igniters that last 3x longer.
Carbon soot and desert moisture coat flame sensors, causing the furnace to light for 3 seconds and shut down. We clean, calibrate, and test microamp signal strength.
If the draft motor cannot evacuate exhaust gases, the pressure switch locks out the system for safety. We carry replacement inducer assemblies.
Shut off your thermostat and call us immediately for emergency safety inspection.
