Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your HVAC system kick on and you’re expecting a cozy blast of warm air, but instead all you feel is cool air blowing. That’s no good in freezing temperatures!

There are a few reasons why your heating equipment could be blowing cold air. Church Services is here with some of them to help you find the issue.

 

  • Thermostat

 

It may sound silly, but the thermostat is the first place you should check. It’s the first place any heating system technician will check, too. Make sure the system is set to “auto as opposed to “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 blasting cold air. Changing it to “auto” will make sure the furnace only blows when it’s actually heating the air to keep your home warm and comfortable.

 

  • Air Filter

 

The majority of air filters need to be changed monthly to keep 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 equipment, causing the furnace to stop heating as a safety measure.

 

  • Duct Work

 

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