Preparing for Winter: Giving your Furnace a Check-up

Is your furnace all set and ready to be turned on? Focusing on maintenance and tune-ups now will save you the frustration next month when you go to turn the unit on and it won't work. Here are some of the areas your HVAC professional will address when they visit your home for your annual furnace check-up.

Inspect Thermostat

Making sure the thermostat is working properly is a crucial part of the check-up because without it, temperature regulation will not happen correctly. Your heating technician will check the connection between the furnace and each thermostat in the home to make sure one is communicating with the other. This is necessary to maintain the exact temperature you desire through the whole house. Cleaning and calibrating the thermostat is one of the major parts of your furnace tune-up.

Change or Clean Filter

Just like AC filters, furnace filters build up dirt and dust over time, which restricts air flow and leads to inefficient operation of the entire unit, says House Logic. In extreme cases, the heat exchanger can overheat and cause a big problem. Read instructions on your filters thoroughly for recommended changing schedules. Some models require simple cleaning and replacement while other types require a brand new filter each time. You can ask your heating specialist to show you how to change the filters so you can manage it on your own throughout the winter.

Check Electrical Connections

If you're a DIY'er, changing the filter or doing a cleaning may not be so daunting, but the electrical connection check is best left to a professional who has the proper equipment and expertise to do so. As part of their inspection, your HVAC professional will ensure all wiring is intact, with no fraying or wear and tear, and that all connections are tight.

Check for Cracks

If the heat exchanger gets damaged in any way or experiences a crack, this can emit deadly carbon monoxide into the home. Fixing any tiny cracks now will save your life and that of your family.

Lubricate Moving Parts

Just like the engine on your car, the parts of a furnace need to work smoothly. For that, they need to be properly lubricated at all times so the unit doesn't suddenly stop functioning.

Other Areas of Concern

When you schedule a furnace tune-up with your heating professional, he or she will let you know before beginning what they will be checking, cleaning and inspecting. The list is long, and varies by make and model, but the basics are always the same. You can expect the following to be part of your tune-up:

  • Inspect and change filter
  • Check electrical components and controls
  • Check air flow and air fuel mixture
  • Clean evaporator coil
  • Adjust gas pressure regulator if needed
  • Check temperature rise
  • Clean pilot assembly
  • Vacuum out burners and controls
  • Adjust burner as needed
  • Check for gas leaks
  • Inspect flue piping
  • Check safety switches and devices
  • Check belt and adjust tension
  • Look at crankcase heater
  • Calibrate thermostat
  • Check condensate drain
