Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your heating system start up and you’re expecting a comfortable blast of warm air, but instead all you get is cool air blowing. That’s not preferable in the freezing weather!

There are a handful of reasons why your furnace could be giving off cold air. Neal Harris Service Experts Heating, Air Conditioning & Plumbing is here with a couple of them to help you find the culprit.

 

  • Thermostat

 

It could sound silly, but the thermostat is the first place you should check. 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 HVAC system will blow continuously, even when it isn’t heating the air coming out, thus putting off cold air. Turning it to “auto” will make sure the heating system only blows when it’s actually heating the air to keep your home warm and comfortable.

 

  • Air Filter

 

Typically air filters need to be changed monthly to keep them from getting dirty and clogged. If your filters aren’t replaced often enough, the soiled air filter may restrict airflow into your heating equipment. If this takes place, it can overheat your equipment, causing the furnace to stop heating as a safeguard.

 

  • Duct Work

 

If your duct work contains leaks, connection issues, or was not designed properly, it could permit warm air from the heating system to seep out. This would not only cause your heating equipment to produce cold air, it could actually 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.
