Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your furnace start up and you’re expecting a comfortable blast of warm air, but instead all you feel is cool air blowing. That’s no good when it’s cold outside!

There are a couple reasons why your furnace could be putting off cold air. Service Experts Heating & Air Conditioning is here with a couple of them to help you locate the problem.

 

  • Thermostat

 

It might feel silly, but the thermostat is the first thing you want to look at. It’s the starting place for any furnace technician, too. Confirm the system is set to “auto instead of “on.” If the thermostat is set to “on” then your HVAC system will blow continually, even when it isn’t heating the air being produced, thus blowing cold air. Flipping it to “auto” will make sure the heating equipment only blows when it’s truly heating the air to keep your home warm and cozy.

 

  • Air Filter

 

Typically air filters need to be changed monthly to prevent them from becoming dirty and clogged. If they aren’t swapped out often enough, the clogged air filter may obstruct airflow into your heating system. If this happens, it can overheat your furnace, causing the equipment to stop heating as a safeguard.

 

  • Duct Work

 

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