Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your HVAC system kick on and you’re anticipating a comfy blast of warm air, but instead all you have is cool air blowing. That’s not what you want in the freezing weather!

There are a handful of reasons why your heating system could be blowing cold air. Service Experts Heating & Air Conditioning is here with a few of them to help you locate the issue.

 

  • Thermostat

 

It could sound silly, but the thermostat is the first thing you want to look at. It’s the starting point for any heating technician, too. Confirm the system is set to “auto instead of “on.” If the thermostat is set to “on” then your furnace will blow constantly, even when it isn’t really heating the air coming out, thus putting off cold air. Flipping it to “auto” will make sure the heating system only blows when it’s actually heating the air to keep your home warm and comfy.

 

  • Air Filter

 

Typically air filters need to be changed every month to keep them from growing dirty and clogged. If they aren’t replaced often enough, the clogged air filter may obstruct airflow into your heating equipment. If this takes place, it can overheat your system, causing the furnace to stop heating as a safety precaution.

 

  • Duct Work

 

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