Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your furnace turn on and you’re expecting 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 couple reasons why your furnace could be giving off cold air. McElroy Service Experts Heating & Air Conditioning is here with a few of them to help you detect the problem.

 

  • Thermostat

 

It might seem 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. Verify the system is set to “auto as opposed to “on.” If the thermostat is set to “on” then your heating system will blow constantly, even when it is not actually heating the air being released, thus blasting cold air. Turning it to “auto” will make sure the heating system only blows when it’s actually heating the air to keep your home warm and comfortable.

 

  • Air Filter

 

Most air filters need to be changed monthly to keep them from growing dirty and clogged. If air filters aren’t swapped out often enough, the dirty air filter may obstruct airflow into your heating equipment. If this occurs, it can overheat your equipment, causing the furnace to stop heating as a safety precaution.

 

  • Duct Work

 

If your duct work contains leaks, connection issues, or was designed incorrectly, it could allow warm air from the heating equipment to escape out. This would not only cause your heating system to produce cold air, it could actually run up your utility bills since your heating system is heating non-living space, and will have to work more to keep your home comfortable.
