Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You notice your HVAC system start up and you’re expecting a comfortable blast of warm air, but instead all you get is cool air blowing. That’s not preferable in freezing temperatures!

There are a few reasons why your furnace could be giving off cold air. Strogen's Service Experts is here with a couple of them to help you locate the culprit.

 

  • Thermostat

 

It may seem silly, but the thermostat is where you should start. It’s the first place any heating system technician will check, too. Confirm the system is set to “auto and not “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 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 comfortable.

 

  • Air Filter

 

The majority of air filters need to be changed monthly to prevent them from growing dirty and clogged. If they aren’t replaced often enough, the clogged air filter may restrict airflow into your furnace. If this occurs, it can overheat your system, causing the equipment to stop heating as a safety precaution.

 

  • Duct Work

 

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