Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You notice your furnace kick on and you’re expecting 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 couple reasons why your heating equipment could be blowing cold air. R & M Climate Control Service Experts Heating & Air Conditioning is here with some of them to help you locate the problem.

 

  • Thermostat

 

It might sound silly, but the thermostat is the first place you should check. It’s the starting place for any furnace technician, too. Verify the system is set to “auto and not “on.” If the thermostat is set to “on” then your HVAC system will blow constantly, even when it is not actually heating the air being produced, thus blasting cold air. Flipping it to “auto” will make sure the furnace only blows when it’s really heating the air to keep your home warm and comfy.

 

  • Air Filter

 

The majority of air filters need to be changed monthly to prevent them from becoming dirty and clogged. If your filters aren’t swapped out often enough, the clogged air filter may impede airflow into your furnace. If this happens, it can overheat your furnace, causing the furnace to stop heating as a safety measure.

 

  • Duct Work

 

If your duct work contains leaks, connection troubles, or was not designed properly, it could let warm air from the heating system to leak out. This would not only cause your heating system to give off 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 at the desired temperature.
