Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your furnace kick on and you’re ready for a comfy blast of warm air, but instead all you get is cool air blowing. That’s not what you want in the freezing weather!

There are a couple reasons why your furnace could be giving off cold air. McElroy Service Experts is here with a few of them to help you detect the culprit.

 

  • 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 furnace will blow constantly, even when it isn’t heating the air being released, thus blasting cold air. Changing 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 avoid them from growing dirty and clogged. If air filters aren’t swapped out often enough, the clogged air filter may restrict airflow into your heating equipment. If this happens, it can overheat your equipment, causing the furnace to stop heating as a safety precaution.

 

  • Duct Work

 

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

 

There are many other reasons that your heating system could produce cold air.
