Troubleshooting Tips for Your Aging Furnace

aging furnaceProblems with an aging furnace are almost inevitable. Your furnace has already given you years or even decades of hard work, and while it was built to last, it wasn’t built to last forever. If you’re having trouble, however, there are some troubleshooting steps you may be able to take to extend its life without needing to schedule a costly repair visit.

  • Check the thermostat – Often, it’s not the furnace but the thermostat that’s causing the problem. It may be an issuing of settings such as not realizing it’s set to cool or that someone else changed the temperature. If it’s set how you want it, it may be too dirty or too worn out to do the job anymore.
  • Check the power – Even gas furnaces use power to ignite themselves and control their temperature. Make sure the wiring is still intact and the breakers haven’t tripped.
  • Check the pilot light – An aging furnace likely has an old style pilot light that’s designed to be constantly on. These lights were often poorly protected and may be blown out by drafts or breezes in your basement. Simply reignite it to get it going again.
  • Check the furnace’s size – Furnaces installed in new construction are often undersized because the builder was trying to cut expenses. Other times, a furnace has become undersized due to additions to a home. If your furnace isn’t heating as well as you’d like, see if it’s properly sized. If it is, you may need a repair. If it’s too small, but otherwise working well, adding zoned heating may be a worthwhile solution.
  • Check for dirt – If you have an aging furnace, it may not have been cleaned properly through the years. Dirt restricts airflow and makes your furnace work harder. Check and clean the filters, vents, ducts and blower to make sure air is able to flow freely.
