My Furnace Is Blowing Cold Air

Posted on: January 11, 2017

The last thing you need during a frigid Chicago winter is for your furnace to blow cold air. The air outside is already cold enough, you don’t need it inside your home, too. After all, it’s your furnace’s job to pump warm air throughout the house so you can come inside and thaw out after spending time in what can seem like a tundra.

If you find yourself getting blasted with cool air inside your home this winter, there are a number of potential causes:

  1. The thermostat is on the wrong setting – check to make sure it’s set to “AUTO” rather than “FAN.” The fan setting means the fan will continue to blow air through the system even if it’s not heating it. Switching it over to AUTO means the fan will only turn on when the system is producing warm air.
  2. The pilot light went out – if you have a gas furnace and it’s not making warm air, there’s a chance the pilot light blew out. You may simply need to relight it, but if that doesn’t solve the problem there could be an issue with the thermocouple. Call in an expert to assess the situation.
  3. You have leaky ducts – sometimes the actual furnace isn’t the problem. If you have leaky air ducts they can allow warm air to escape through cracks or gaps. This also means cold air can get into the ducts and blow throughout your home.

Whatever the case may be, the heating professionals at ABC have the knowledge and expertise to get your system back up and running in no time. Give us a call to schedule an appointment – don’t get left out in the cold!
