How to Ensure Quality and Avoid Scams When Selecting a Furnace Repair Service
First of all, be aware that not all furnaces have a reset button; however, most do. If your electric furnace has one, it's most likely located within the blower housing, next to the motor. If you own a gas furnace, it's probably located within the control panel. Check your owner's manual for specifics.
To test the furnace, temporarily set the thermostat five to ten degrees higher than you normally would to see if it comes on, then return the thermostat to its normal setting when the test is complete. Check the gas supply. Make sure your gas supply line is open.
