Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear 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 what you want in the freezing weather!

There are a couple reasons why your furnace could be putting off cold air. A-PLUS Service Experts is here with a few of them to help you locate the culprit.

 

  • Thermostat

 

It could seem silly, but the thermostat is the first place you should check. It’s the starting place for any furnace technician, too. Make sure the system is set to “auto and not “on.” If the thermostat is set to “on” then your furnace will blow continually, even when it isn’t really heating the air being released, thus blowing cold air. Changing it to “auto” will make sure the heating system 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 once a month to avoid them from getting dirty and clogged. If they aren’t replaced often enough, the clogged air filter may obstruct airflow into your heating system. If this occurs, it can overheat your furnace, causing the furnace to stop heating as a safeguard.

 

  • Duct Work

 

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