Top Furnace Troubleshooting Tips

1. No heat: Check thermostat settings, make sure it’s set to “Heat” and the temperature is set higher than the current room temperature. Also, ensure the furnace switch is turned on and the circuit breaker hasn’t tripped.

2. Furnace won’t start: Check the pilot light, if it’s out, relight it. If the pilot light won’t stay lit, the thermocouple may need to be replaced.

3. Blowing cold air: Check the air filter, it may need to be replaced if it’s dirty. Also, make sure the thermostat is set to “Heat” and the temperature is set higher than the current room temperature.

4. Furnace making strange noises: Loud banging or popping noises may indicate a malfunctioning blower motor or loose parts. Rumbling or whistling sounds may be due to a clogged air filter.

5. Intermittent heat: Check the thermostat, it may need to be replaced if it’s not functioning properly. Also, ensure there are no obstructions blocking the air ducts.

6. Yellow pilot light: This could indicate a carbon monoxide leak, which is a serious issue. Contact a professional HVAC technician immediately.

7. Furnace constantly cycling on and off: This could be due to a dirty air filter, a malfunctioning thermostat, or a clogged air duct.

In conclusion, regular maintenance and quick troubleshooting can help keep your furnace running smoothly and prevent more serious issues. If you’re unsure about how to fix a problem, contact a professional Luxury Air HVAC technician for assistance.
