Before reaching out to your HVAC company in Minnetonka MN when your furnace isn’t working, run through this checklist to potentially resolve the issue and save time and money on a service call.
-
Check the Thermostat:
- Ensure it’s set to the heat mode.
- Increase the temperature by five degrees to prompt activation.
- Clean the thermostat by removing the cover and dusting it gently. For programmable thermostats, refer to the manual.
-
Inspect the Blower:
- Confirm it’s not accidentally turned off.
- Reset the furnace breaker in the circuit-breaker box.
-
Examine the Air Filter:
- A dirty filter can impede airflow, causing the furnace to shut off prematurely.
- Check and replace the filter monthly for optimal performance.
-
Verify Gas Supply:
- Ensure the gas valve supplying your home is turned on.
-
Inspect the Flue:
- Check for blockages caused by birds or debris.
- Turn off the furnace before cleaning the flue.
-
Clear the Drainpipe:
- For high-efficiency systems, a clogged drainpipe could be the issue.
- Flush it with a 25% bleach and 75% water mixture, then rinse with clear water.
-
Check Airflow at Registers:
- Confirm each register is receiving airflow; ductwork issues may be present if not.
-
Clear Furnace Vents Outdoors:
- Remove any blockages from outdoor furnace vents.
