Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You notice your HVAC system turn on and you’re expecting a cozy 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 handful of reasons why your heating equipment could be giving off cold air. Service Experts Heating & Air Conditioning is here with a couple of them to help you find the culprit.

 

  • Thermostat

 

It could feel silly, but the thermostat is where you should start. It’s the starting point for any heating 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 continually, even when it isn’t heating the air coming out, thus putting off cold air. Changing it to “auto” will make sure the heating equipment only blows when it’s truly heating the air to keep your home warm and cozy.

 

  • Air Filter

 

Typically air filters need to be changed every month to keep them from becoming dirty and clogged. If your filters aren’t replaced often enough, the soiled air filter may obstruct airflow into your heating equipment. If this happens, it can overheat your system, causing the furnace to stop heating as a safeguard.

 

  • Duct Work

 

If your duct work has leaks, connection issues, or was not designed properly, it could allow warm air from the furnace to seep out. This would not only cause your furnace to produce cold air, it could seriously run up your heating bills since your heating equipment is heating non-living space, and will have to work harder to keep your home comfortable.
