5 Common Reasons Why Your Furnace is Blowing Cold Air

5 Common Reasons Why Your Furnace is Blowing Cold Air

As the temperature outside gets lower and lower, you’ll likely turn up the heat to stay more comfortable. But when you do, you find out that you’re stuck with chilly air blowing indoors—which isn’t right! So, what’s going on? Is your furnace broken or something?

The icy blast from your furnace is triggered by several reasons such as the following:

Thermostat Issues

In some cases, the problem might not be the furnace itself.  Other causes are external like thermostat issues. There’s a high chance that your thermostat is set incorrectly, is low on battery, or is installed wrong; that’s why your furnace is blowing an Arctic chill in your home instead of warm air.

Thermostat issues may come in different flavors with different solutions, so you’ll need the help of professionals to identify the issue. Consult your HVAC contractor for an inspection as soon as possible.

The Filter is Dirty!

Through the winter months, your furnace filters have caught a significant amount of dust and debris, which means they can get clogged over time. Clogging in the filters due to excessive dirt limits the airflow to your furnace—causing it to overheat and shut off. Check the filters and replace them if necessary.

Faulty or Worn Out Valve

For gas furnaces that haven’t been cleaned for a long time, gas valve issues could be the reason for the cold air blowing from your system. The valve might need cleaning or replacement—depending on the issue. Be sure to check the valve regularly to know its status.

Problems at the Fuel Source

Not all homeowners would check the fuel source of their furnace from time to time. So when the system went out and started to give off a chill, you might need to take a few minutes to check the power source. Depending on the furnace type, you have to check the following:

  • Electric Furnace:  See if the furnace is turned on at the breaker panel.
  • Gas Furnaces: Check if the gas valve is open.
  • Oil Furnaces: Make sure there’s oil in the tank.

Leaky Ducts

Other external issues that cause frosty air from your furnace are leaky ducts. The hot air could be leaking through the holes and gaps in the duct system. With leaking ductwork, don’t expect to get warm air from your furnace.
