Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your furnace turn on and you’re anticipating a cozy blast of warm air, but instead all you have is cool air blowing. That’s not preferable in freezing temperatures!

There are a couple reasons why your heating equipment could be blowing cold air. Service Experts Heating & Air Conditioning is here with a few of them to help you find the culprit.

 

  • Thermostat

 

It may sound silly, but the thermostat is the first place you should check. It’s the starting point for any heating technician, too. Verify the system is set to “auto as opposed to “on.” If the thermostat is set to “on” then your furnace will blow constantly, even when it isn’t really heating the air being released, thus blasting cold air. Flipping it to “auto” will make sure the furnace only blows when it’s really heating the air to keep your home warm and comfortable.

 

  • Air Filter

 

The majority of air filters need to be changed once a month to avoid them from getting dirty and clogged. If air filters aren’t changed often enough, the clogged air filter may impede airflow into your furnace. If this occurs, it can overheat your system, causing the equipment to stop heating as a safety measure.

 

  • Duct Work

 

If your duct work has leaks, connection problems, or was not designed properly, it could let warm air from the heating equipment to leak out. This would not only cause your heating equipment to blow cold air, it could seriously run up your utility bills since your heating system is heating non-living space, and will have to work more to keep your home at the desired temperature.
