Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your HVAC system turn on and you’re ready for a cozy blast of warm air, but instead all you feel is cool air blowing. That’s not preferable in freezing temperatures!

There are a few reasons why your heating system could be giving off cold air. Boehmers/Cronin Emery Service Experts is here with some of them to help you detect the culprit.

 

  • Thermostat

 

It might feel 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. Confirm 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 coming out, thus blowing cold air. Turning it to “auto” will make sure the furnace only blows when it’s really heating the air to keep your home warm and cozy.

 

  • Air Filter

 

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

 

  • Duct Work

 

If your duct work has leaks, connection troubles, or was designed incorrectly, it could let warm air from the furnace to seep out. This would not only cause your furnace to blow cold air, it could significantly run up your heating bills since your heating equipment is heating non-living space, and will have to work more to keep your home warm.
