Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your HVAC system kick on and you’re anticipating a cozy blast of warm air, but instead all you feel is cool air blowing. That’s not what you want in freezing temperatures!

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

 

  • Thermostat

 

It might sound silly, but the thermostat is the first thing you want to look at. It’s the first place any heating system technician will check, too. Make sure the system is set to “auto and not “on.” If the thermostat is set to “on” then your HVAC system will blow continually, even when it is not actually heating the air being released, thus putting off cold air. Flipping 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

 

Most air filters need to be changed once a month to avoid them from getting dirty and clogged. If your filters aren’t swapped out often enough, the dirty air filter may restrict airflow into your heating equipment. If this takes place, it can overheat your equipment, causing the system to stop heating as a safety measure.

 

  • Duct Work

 

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