Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your furnace turn on and you’re expecting a comfortable blast of warm air, but instead all you have is cool air blowing. That’s not what you want in the freezing weather!

There are a couple reasons why your furnace could be giving off cold air. Service Experts Heating & Air Conditioning is here with a few of them to help you find the issue.

 

  • Thermostat

 

It may sound silly, but the thermostat is where you should start. It’s the starting place for any furnace technician, too. Verify the system is set to “auto instead of “on.” If the thermostat is set to “on” then your HVAC system will blow continuously, even when it isn’t really heating the air being released, thus putting off cold air. Changing 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

 

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

 

  • Duct Work

 

If your duct work includes leaks, connection issues, or was designed incorrectly, it could allow warm air from the furnace to leak out. This would not only cause your heating equipment to blow cold air, it could seriously run up your energy bills since your furnace is heating non-living space, and will have to work harder to keep your home at the desired temperature.
