Why Your Furnace Could be Blowing Cold Air

October 21, 2016

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

There are a handful of reasons why your furnace could be giving off cold air. Service Experts Heating & Air Conditioning is here with some of them to help you find the problem.

 

  • Thermostat

 

It could feel silly, but the thermostat is the first place you should check. It’s the first place any heating system technician will check, too. Confirm the system is set to “auto as opposed to “on.” If the thermostat is set to “on” then your furnace will blow continuously, even when it isn’t heating the air being produced, thus putting off cold air. Flipping it to “auto” will make sure the heating system only blows when it’s actually heating the air to keep your home warm and cozy.

 

  • Air Filter

 

The majority of air filters need to be changed once a month to avoid them from getting dirty and clogged. If they aren’t changed often enough, the dirty air filter may impede airflow into your furnace. If this happens, it can overheat your system, causing the system to stop heating as a safeguard.

 

  • Duct Work

 

If your duct work has leaks, connection issues, or was not designed correctly, it could permit warm air from the heating system to escape out. This would not only cause your heating equipment to produce cold air, it could actually run up your energy bills since your heating equipment is heating non-living space, and will have to work harder to keep your home at the desired temperature.
