Why Your Furnace Could be Blowing Cold Air

October 21, 2016

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

There are a couple reasons why your furnace could be putting off cold air. Service Experts Heating & Air Conditioning is here with some of them to help you locate the culprit.

 

  • Thermostat

 

It might seem silly, but the thermostat is the first place you should check. It’s the first place any heating system technician will check, too. Confirm 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 is not actually heating the air coming out, thus blowing cold air. Turning it to “auto” will make sure the heating equipment only blows when it’s really heating the air to keep your home warm and comfortable.

 

  • Air Filter

 

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

 

  • Duct Work

 

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