Simple Troubleshooting Tips Before Calling a Professional
Before scheduling a service call, you can check a few common issues that may be causing your furnace to malfunction:
- Thermostat Settings: Ensure it is set to “heat” and the desired temperature is above the room temperature.
- Power Supply: Confirm your furnace has electricity and that breakers or switches haven’t tripped.
- Air Filter: A clogged filter can restrict airflow and trigger safety switches. Replace or clean filters as needed.
- Pilot or Ignition System: Some units have pilot lights or electronic ignition systems that may need attention.
These quick checks can sometimes solve minor problems and may help you avoid unnecessary downtime.

Step-by-Step Furnace Troubleshooting Checklist
- Check the Thermostat
- Digital thermostats: Ensure it’s set to “heat” and batteries are working. Set temperature 5°F above room temp.
- Smart thermostats: Follow manufacturer instructions; call us if the issue persists.
- Inspect Breakers and Switches
- Confirm the furnace breaker hasn’t tripped. Reset only if safe; call if it trips again.

- Check the Condensate Pan
- Look for water buildup, ensure drain pipes are clear, and verify float switches function properly.
