Common Furnace Problems We Repair

Furnace breakdowns are often caused by failed electrical controls, dirty sensors, or airflow restrictions. We repair all major brands and system types:

Igniter & Flame Sensor Faults

Cracked hot-surface igniters or carbon-coated flame sensors cause the furnace to attempt ignition three times before entering safety lockout.

Blower Motor & Capacitor Failures

Worn blower bearings, failed run capacitors, or dirty fan wheels prevent proper heat circulation and lead to high-limit heat exchanger tripping.

Draft Inducer & Pressure Switches

Restricted flue venting, clogged condensate traps, or failing draft inducer motors prevent pressure switches from closing safely.

Thermostat & Communication Errors

Faulty low-voltage wiring, improper thermostat configuration, or blown control board fuses cause intermittent heat loss.

What We Inspect During Repair Visits

✓ Gas valve manifold pressure check

✓ Flame sensor & igniter resistance

✓ High-limit safety switch testing

Frequently Asked Questions

Why is my furnace blowing cold air instead of hot air? Cold air coming from vents usually means the blower fan is running, but the burners failed to light or tripped off. Common causes include dirty flame sensors, tripped high-limit switches from dirty filters, or failed hot-surface igniters.

What does it mean when my furnace keeps turning on and off quickly (short cycling)? Short cycling happens when the furnace overheats due to restricted airflow (dirty air filter or blocked registers), causing the high-limit switch to cut power to the gas valve to prevent heat exchanger damage.
