Call an Electrician if:
Power Issues
- The furnace doesn’t turn on, and no power seems to reach it.
- The circuit breaker for the furnace keeps tripping.
- You suspect wiring issues, such as loose or damaged connections.
Call a Heating (HVAC) Technician if:
Heating Issues
- The furnace turns on but doesn’t produce heat.
- The furnace shuts off too soon or cycles on and off frequently.
Airflow Problems
- The furnace is running, but there’s no air or reduced airflow.
- Could be a clogged filter or duct work issue.
Unusual Noises or Smells
- You hear banging, grinding, or whistling noises or notice a burning smell unrelated to electrical wiring.
Thermostat Problems
- The thermostat is unresponsive or malfunctioning.
Steps to Take Before Calling:
- Check the Thermostat: Ensure it’s set to "heat" and the temperature is above room temperature.
- Inspect the Breaker: Reset the furnace circuit breaker if it has tripped.
- Change or Clean the Filter: A clogged filter can cause airflow or overheating issues.
- Check the Power Switch: Ensure the furnace’s power switch is on.
- Look for Error Codes: Some furnaces have indicator lights or error codes you can reference in the user manual.
Who to Call First?
If the furnace doesn’t power on or the issue seems electrical: Call an electrician.
If the furnace powers on but isn’t heating or functioning correctly: Call a heating technician.
If you're unsure, starting with a heating technician is usually a safe bet, as they can address both HVAC-specific issues and may identify electrical problems requiring an electrician.
