How do I weatherize a heating system?

Updated Tuesday, July 22


Most heating systems are reliable and provide quick, comfortable heat when you need it – if you take good care of the system. If you have air conditioning, shut it down and cover it for the winter. Please follow these steps prior to furnace use:

  1. Clean or change the furnace filter.
  2. If your furnace or boiler has a pilot light, ensure it is on.
  3. Set the furnace to the “heat” position. Turn up the thermostat.
  4. Let the furnace run through a couple of cycles to make sure it’s working properly.
  5. Perform a quick visual inspection of the furnace area to make sure there are no items that could interfere with airflow or combustion.
  6. Call or text Franzen Heating & Cooling to arrange for professional cleaning, inspection, and precision tune-up services.
