Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your HVAC system turn on and you’re anticipating a cozy blast of warm air, but instead all you get is cool air blowing. That’s no good in freezing temperatures!

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

 

  • Thermostat

 

It might seem silly, but the thermostat is the first thing you want to look at. It’s the first place any heating system technician will check, too. Make sure the system is set to “auto and not “on.” If the thermostat is set to “on” then your furnace will blow continually, even when it is not actually heating the air being produced, thus blowing cold air. Changing 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 keep them from growing dirty and clogged. If your filters aren’t changed often enough, the soiled air filter may impede airflow into your heating system. If this occurs, it can overheat your furnace, causing the equipment to stop heating as a safeguard.

 

  • Duct Work

 

If your duct work contains leaks, connection issues, or was designed incorrectly, it could permit warm air from the heating equipment to seep out. This would not only cause your heating equipment to blow cold air, it could actually run up your energy bills since your furnace is heating non-living space, and will have to work more to keep your home warm.

 

There are many other reasons that your heating equipment could produce cold air.
