If your furnace is letting you down with temperatures that aren’t high enough, any number of things can be wrong with it.  The problem is, there’s no way we can pinpoint the cause without seeing it up close and in person.

But before requesting service, a little DIY inspection activity could end up saving you the cost of a service call.

Here are simple and quick ways to see (hopefully) what’s going on.

 

Wrong with My Furnace?

Troubleshooting Common Furnace Issues

  • No power. If your furnace isn’t running at all, it’s only logical to see if the power supply is shut off. First, check your thermostat to see if it’s in the “on” position.  If so, try turning it up 5 – 10 degrees to see if your furnace responds.  If there’s still no sign of life, check your fuse box or circuit breaker panel and the furnace itself to ensure a loss of power isn’t the problem. If it is, the remedy is quick and simple.
  • No heat. If you can hear the furnace but cold air is pouring through your vents, check the thermostat just in case the “heat” setting got changed to “cool”.
  • Not enough heat. If you keep having to spike the thermostat to reach the desired temperature, a clogged filter could be blocking much of the warm air you depend on for adequate comfort. See if you can locate the filter and, if it’s dirty, clean or replace it as needed.
  • Is yours a battery-operated thermostat? Not all thermostats are electrically wired directly to your furnace.  Some operate by batteries, and batteries eventually need to be replaced.
  • How about the pilot light? Older furnaces have them – even some newer models. If that includes your furnace, check the pilot light to see if it’s lit and, if not, relight it.  If it’s yellow vs. blue, it’s time to call for professional assistance.
