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 feel is cool air blowing. That’s no good when it’s cold outside!

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

 

  • Thermostat

 

It could sound 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 heating system will blow constantly, even when it is not actually heating the air coming out, thus blasting cold air. Turning it to “auto” will make sure the furnace only blows when it’s truly heating the air to keep your home warm and comfy.

 

  • 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 clogged air filter may impede airflow into your heating system. If this occurs, it can overheat your system, causing the furnace to stop heating as a safety precaution.

 

  • Duct Work

 

If your duct work has leaks, connection problems, or was not designed properly, it could permit warm air from the heating equipment to leak out. This would not only cause your furnace 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 several other reasons that your furnace could give off cold air.
