Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your heating system start up and you’re anticipating a cozy blast of warm air, but instead all you get is cool air blowing. That’s no good in the freezing weather!

There are a handful of reasons why your heating equipment could be giving off cold air. Air Engineers Service Experts is here with a few of them to help you find the problem.

 

  • Thermostat

 

It may seem silly, but the thermostat is the first thing you want to look at. It’s the starting point for any heating technician, too. Confirm the system is set to “auto and not “on.” If the thermostat is set to “on” then your furnace will blow continuously, even when it is not actually heating the air being produced, thus blasting cold air. Flipping it to “auto” will make sure the furnace only blows when it’s truly heating the air to keep your home warm and comfortable.

 

  • Air Filter

 

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

 

  • Duct Work

 

If your duct work includes leaks, connection problems, or was not designed properly, it could let warm air from the heating system to leak out. This would not only cause your furnace to produce cold air, it could actually run up your heating bills since your heating equipment is heating non-living space, and will have to work overtime to keep your home comfortable.
