My Furnace Is NOT Working! What to Check BEFORE Calling For Furnace Repair

What to check when furnace not working?

If you are concerned that your furnace may not be working… whether your furnace is not turning on or if your furnace is blowing cold air, there are some initial checks you can do yourself.

If your furnace is not working, first ask yourself if anyone has been around or adjusted your HVAC system recently.

Sometimes your furnace power switch can be turned off or a furnace door does not get closed properly which can cause your furnace to not work.

These are innocent problems that when found, can save you a service call!

Other things to check when your furnace is not working:

1. A dirty filter could cause your furnace to not work.

2. If your furnace vents out the side of your house, make sure the vent is not blocked.

3. Make sure your thermostat is set to heat with a temperature that would call for heat.

If all of the above suggestions are in order and your furnace is still not working, try to do a reset of your furnace. Shut off the power to the furnace for about 10 seconds and then turn it back on. Sometimes that can help.
