Furnace Repair Services We Offer in Escondido
✓Ignitor and Flame Sensor Replacement
Contractors replace cracked hot-surface ignitors and dirty flame sensors that cause no-heat calls after summer storage, restoring reliable ignition without repeated lockouts.
✓Blower Motor and Capacitor Repair
Technicians test and replace worn blower motors or weak capacitors that produce weak airflow or humming in homes with extended runtime demands.
✓Heat Exchanger Inspection
Contractors use cameras and combustion testing to locate cracks in older units that risk carbon monoxide leakage into living spaces.
✓Gas Valve and Thermocouple Repair
Service providers clean or replace failing gas valves and thermocouples that prevent proper burner operation or create safety shutdowns.
✓Thermostat Diagnosis and Calibration
Contractors verify wiring, recalibrate sensors, and resolve communication issues that cause short cycling or uneven temperatures across zones.
✓Pilot Light and Ignition Troubleshooting
Technicians diagnose draft problems, dirty orifices, and thermocouple failures that extinguish the pilot or block electronic ignition sequences.
In older California homes, heat exchangers in 20- to 40-year-old furnaces develop cracks that allow combustion gases to mix with household air, creating carbon monoxide hazards. Homeowners often notice a metallic smell or soot near vents during the first cold snap after summer. Contractors inspect the exchanger with mirrors and cameras, test for leaks using combustion analyzers, and recommend replacement when cracks appear rather than attempting welds that fail under thermal cycling.
Long idle periods during California summers cause ignitors, flame sensors, and thermocouples to oxidize or crack, leading to failed ignition attempts or short cycling. Residents hear repeated clicking without burner engagement or smell unburned gas briefly. A contractor removes the sensor, cleans or replaces it, verifies flame rectification signals, and checks the gas valve for proper pressure to restore reliable starts without repeated lockouts.
