Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your HVAC system turn on and you’re ready for a cozy blast of warm air, but instead all you feel is cool air blowing. That’s not what you want in the freezing weather!

There are a few reasons why your heating system could be blowing cold air. A-PLUS Service Experts Heating & Air Conditioning is here with some of them to help you locate the culprit.

 

  • Thermostat

 

It could seem silly, but the thermostat is the first place you should check. It’s the starting place for any furnace technician, too. Make sure the system is set to “auto instead of “on.” If the thermostat is set to “on” then your heating system will blow constantly, even when it isn’t really heating the air being released, thus putting off cold air. Turning it to “auto” will make sure the furnace only blows when it’s really heating the air to keep your home warm and cozy.

 

  • Air Filter

 

Most air filters need to be changed once a month to keep them from getting dirty and clogged. If air filters aren’t changed often enough, the dirty air filter may restrict airflow into your heating system. If this occurs, it can overheat your system, causing the system to stop heating as a safeguard.

 

  • Duct Work

 

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