Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You notice your heating system turn on and you’re expecting a comfortable blast of warm air, but instead all you get is cool air blowing. That’s no good when it’s cold outside!

There are a couple reasons why your furnace could be blowing cold air. Roland J. Down Service Experts is here with some of them to help you find the issue.

 

  • Thermostat

 

It might seem silly, but the thermostat is where you should start. It’s the starting point for any heating technician, too. Make sure the system is set to “auto as opposed to “on.” If the thermostat is set to “on” then your furnace will blow continuously, even when it isn’t heating the air being produced, thus blasting cold air. Changing it to “auto” will make sure the heating equipment 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 becoming dirty and clogged. If they aren’t replaced often enough, the clogged air filter may obstruct airflow into your heating system. If this happens, it can overheat your system, causing the system to stop heating as a safety measure.

 

  • Duct Work

 

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