Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your HVAC system start up and you’re anticipating 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 handful of reasons why your heating equipment could be putting off cold air. Service Experts Heating & Air Conditioning is here with some of them to help you locate the culprit.

 

  • Thermostat

 

It could feel silly, but the thermostat is where you should start. It’s the starting point for any heating technician, too. Confirm the system is set to “auto and not “on.” If the thermostat is set to “on” then your furnace will blow constantly, even when it isn’t really heating the air being produced, thus blasting cold air. Turning it to “auto” will make sure the heating equipment only blows when it’s really heating the air to keep your home warm and comfortable.

 

  • Air Filter

 

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

 

  • Duct Work

 

If your duct work includes leaks, connection issues, or was designed incorrectly, it could allow warm air from the heating system to seep out. This would not only cause your heating system to give off cold air, it could actually run up your energy bills since your heating system is heating non-living space, and will have to work more to keep your home comfortable.
