Furnace Repair by Treat’s Heating & Cooling
Now that the season is here that requires you to stay warm, your furnace might be blowing cold air. Here are a few troubleshooting items that may help you figure out what to do next.
- Its normal – If you’re only getting a bit of cold air when your furnace first kicks on, but the air after a few minutes in is nice and warm, you’re likely just fine. Think of it like turning on a hot water tap. The same effect happens with your furnace. It must push out the cold air from the vents before the warm air can come.
- Thermostat – If there’s a constant flow of cool air coming from your furnace, you probably have your thermostat set incorrectly. When you turn your furnace on for the first time, be sure that the fan is set to “auto” and not “on.” When your fan is set to “auto,” it will only come on when the furnace is on, instead of running all of the time.
- Pilot light – If your furnace is only blowing cold air, your pilot light may be out. Double check your pilot light, and if it’s gone out, relight it. If you have to keep relighting your pilot light, contact Treat’s Heating & Cooling for an expert diagnosis.
- Dirty sensors – If your furnace starts out warm but turns cold quickly, you could be dealing with a dirty flame sensor. A dirty flame sensor tells the furnace to turn off the burner, thus resulting in cold air after it’s initially warm. It’s best to call a heating professional to clean the sensor. Making sure to have annual furnace maintenance performed will help you avoid this issue in the future.
