Is there anything more frustrating? You kick on the furnace, all ready to warm up and all you get is cold air from the ducts! What do you do now? Well first, don’t panic. Second, run down our list of the most common reasons why your furnace is blowing cold air!
Ask yourself these three questions first thing when you notice that your furnace is blowing cold air:
- Question #1 – Is the thermostat set to the ON or AUTO position? The ON position means that your system is blowing neutral air throughout your system continuously and not the air is being warmed. For this reason, your thermostat needs to be set to AUTO in order to kick the furnace on and blow out the warm air you are looking for.
- Question #2 – Has the air filter been changed properly? An air filter that had not been changed properly will cause your furnace to overheat since air cannot properly pass through it. When your furnace overheats, your burners will shut down due to safety controls. This will in turn cause your furnace to blow unheated air.
- Question #3 – Is the pilot light on? This seems like a simple fix – relight the pilot light and you’re back in business. But before you think you are out of the woods, make sure the pilot light stays lit. It may have gone out because of a problem in the ignition system. If you relight and it goes back out, you’ll need to call an expert out to take a look.
