Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your HVAC system kick on and you’re expecting a cozy blast of warm air, but instead all you have is cool air blowing. That’s no good in freezing temperatures!

There are a couple reasons why your furnace could be putting off cold air. Strand Brothers Service Experts is here with a few of them to help you detect 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. Verify the system is set to “auto and not “on.” If the thermostat is set to “on” then your furnace will blow continually, even when it isn’t really heating the air being produced, thus putting off cold air. Changing it to “auto” will make sure the furnace only blows when it’s actually heating the air to keep your home warm and comfy.

 

  • Air Filter

 

The majority of air filters need to be changed monthly to avoid them from growing dirty and clogged. If your filters aren’t replaced often enough, the clogged air filter may impede airflow into your heating system. If this occurs, it can overheat your system, causing the furnace to stop heating as a safety measure.

 

  • Duct Work

 

If your duct work has leaks, connection issues, or was not designed correctly, it could let warm air from the heating system to leak out. This would not only cause your furnace to produce cold air, it could actually run up your heating bills since your heating system is heating non-living space, and will have to work overtime to keep your home warm.
