Furnace Repair
Diagnosis and repair of gas and electric furnaces, including igniter, heat exchanger, blower motor, and control board issues
⚠️ Warning Signs You Need Furnace Repair
- ⚠ Furnace won't ignite or turns off after a few minutes of running
- ⚠ Yellow or flickering flame instead of a steady blue flame (gas furnaces)
- ⚠ Carbon monoxide detector alarming in the home — evacuate and call 911 immediately
- ⚠ Unusual smell from supply vents — burning dust at startup is normal; persistent chemical or gas odor is not
- ⚠ Unusually high gas bills without change in usage — a sign of combustion inefficiency
- ⚠ Cold spots throughout the home that don't respond to thermostat adjustments
- ⚠ Furnace age over 18–20 years — heat exchanger failure risk increases significantly at this age
What to Do: Step-by-Step
- 1 Check the thermostat — ensure it's set to "heat" and the temperature setting is above room temperature
- 2 Check the furnace filter — a severely clogged filter can trigger the furnace's high-limit switch causing shutdown
- 3 Verify the furnace power switch (usually on the wall near the furnace) is in the "on" position
- 4 Check the circuit breaker for the furnace and reset if tripped
- 5 Verify the gas supply valve near the furnace is open (handle parallel to the gas line)
- 6 If the furnace still doesn't light, call a licensed HVAC or gas contractor — never attempt to repair gas components yourself
- 7 Ask the technician to inspect the heat exchanger for cracks during any furnace repair — a cracked heat exchanger is a carbon monoxide hazard
