Why Your Furnace Could be Blowing Cold Air

October 21, 2016

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

There are a few reasons why your heating equipment could be putting off cold air. Coastal Service Experts is here with a few of them to help you find the problem.

 

  • Thermostat

 

It could feel silly, but the thermostat is where you should start. 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 heating the air coming out, thus blasting cold air. Turning it to “auto” will make sure the heating system only blows when it’s actually heating the air to keep your home warm and cozy.

 

  • Air Filter

 

Typically air filters need to be changed once a month to prevent them from growing dirty and clogged. If your filters aren’t replaced often enough, the dirty air filter may impede airflow into your heating system. If this happens, it can overheat your furnace, causing the furnace to stop heating as a safety precaution.

 

  • Duct Work

 

If your duct work contains leaks, connection problems, or was designed incorrectly, it could permit warm air from the heating equipment to escape out. This would not only cause your heating system to produce cold air, it could significantly run up your utility bills since your heating system is heating non-living space, and will have to work more to keep your home comfortable.

 

There are many other reasons that your heating system could give off cold air.
