Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your HVAC system turn on and you’re ready for a comfortable blast of warm air, but instead all you feel is cool air blowing. That’s not preferable when it’s cold outside!

There are a few reasons why your heating equipment could be putting off cold air. Service Experts Heating & Air Conditioning is here with a few of them to help you locate the issue.

 

  • Thermostat

 

It may feel silly, but the thermostat is where you should start. It’s the first place any heating system technician will check, too. Verify the system is set to “auto instead of “on.” If the thermostat is set to “on” then your furnace will blow continually, even when it isn’t really heating the air being released, thus putting off cold air. Flipping it to “auto” will make sure the heating system only blows when it’s actually heating the air to keep your home warm and comfy.

 

  • Air Filter

 

The majority of air filters need to be changed once a month to keep them from becoming dirty and clogged. If your filters aren’t changed often enough, the dirty air filter may restrict airflow into your heating equipment. If this takes place, it can overheat your equipment, causing the equipment to stop heating as a safety precaution.

 

  • Duct Work

 

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

 

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