Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You notice your HVAC system kick on and you’re expecting a comfy blast of warm air, but instead all you get is cool air blowing. That’s no good in the freezing weather!

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

 

  • Thermostat

 

It could feel silly, but the thermostat is the first place you should check. It’s the starting place for any furnace technician, too. Verify the system is set to “auto and not “on.” If the thermostat is set to “on” then your heating system will blow continually, even when it is not actually heating the air being produced, thus blasting cold air. Flipping 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 getting dirty and clogged. If your filters aren’t swapped out often enough, the dirty air filter may obstruct airflow into your heating equipment. If this happens, it can overheat your equipment, causing the furnace to stop heating as a safety precaution.

 

  • Duct Work

 

If your duct work contains leaks, connection troubles, or was designed incorrectly, it could allow warm air from the heating equipment to leak out. This would not only cause your heating equipment to give off cold air, it could significantly run up your heating bills since your heating system is heating non-living space, and will have to work harder to keep your home warm.
