Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your furnace start up and you’re ready for a comfy 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 heating system could be blowing cold air. Knochelmann Service Experts is here with some of them to help you detect the culprit.

 

  • Thermostat

 

It might sound 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 HVAC system will blow continually, even when it isn’t heating the air coming out, thus blowing cold air. Turning it to “auto” will make sure the heating system only blows when it’s truly heating the air to keep your home warm and cozy.

 

  • Air Filter

 

The majority of air filters need to be changed monthly to prevent them from growing dirty and clogged. If air filters aren’t changed often enough, the dirty air filter may restrict airflow into your heating system. If this takes place, it can overheat your system, causing the equipment to stop heating as a safeguard.

 

  • Duct Work

 

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