Some hot tips on furnace maintenance.

 

 Here are some things you can tackle yourself:

 

  • Confirm that the furnace comes on and turns off via your thermostat by setting the temperature higher than the current indoor temperature and setting the system to heating mode.

  • Check the temperature of your supply air grates  to ensure you’re able to feel warm.

  • If you have an older thermostat, which could have liquid mercury switches, clean and level it to ensure proper functioning.

  • Check all visible wiring and electrical connections for signs of damage like burns, unraveling wires and loose nuts.

  • Check your vent-connection pipe and chimney for rust or gaps—venting system parts can deteriorate over time.

  • If you have a gas or oil furnace as part of your heating system, make sure you have a clean and properly sized filter in place.

  • At the start-up of your system each fall, an inspection of the burners, combustion area, venting and even flame appearance is advised. For gas furnaces, an inspection of the air intake and winterization is needed.
