Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your heating system kick on and you’re ready for a comfy 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 heating system could be blowing cold air. Finch Air Conditioning & Heating Inc is here with some of them to help you detect the culprit.

 

  • Thermostat

 

It might seem silly, but the thermostat is where you should start. It’s the starting place for any furnace technician, too. Verify the system is set to “auto as opposed to “on.” If the thermostat is set to “on” then your HVAC system will blow continuously, even when it isn’t heating the air being produced, thus blasting cold air. Changing it to “auto” will make sure the heating system only blows when it’s actually heating the air to keep your home warm and cozy.

 

  • Air Filter

 

Most air filters need to be changed once a month to keep them from growing dirty and clogged. If air filters aren’t swapped out often enough, the soiled air filter may obstruct airflow into your heating system. If this happens, it can overheat your equipment, causing the equipment to stop heating as a safety measure.

 

  • Duct Work

 

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