Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your HVAC system start up and you’re anticipating a cozy blast of warm air, but instead all you have is cool air blowing. That’s not what you want in the freezing weather!

There are a handful of reasons why your heating system could be giving off cold air. Sunbeam Service Experts is here with a few of them to help you detect the issue.

 

  • Thermostat

 

It may sound silly, but the thermostat is where you should start. It’s the starting place for any furnace technician, too. Make sure the system is set to “auto and not “on.” If the thermostat is set to “on” then your furnace will blow constantly, even when it isn’t really heating the air coming out, thus putting off cold air. Changing it to “auto” will make sure the heating system only blows when it’s really heating the air to keep your home warm and cozy.

 

  • Air Filter

 

Typically air filters need to be changed every month to prevent them from growing dirty and clogged. If air filters aren’t swapped out often enough, the clogged air filter may obstruct airflow into your furnace. If this happens, it can overheat your system, causing the equipment to stop heating as a safety measure.

 

  • Duct Work

 

If your duct work has leaks, connection problems, or was designed incorrectly, it could let warm air from the heating equipment to seep out. This would not only cause your heating equipment 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 overtime to keep your home at the desired temperature.
