Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your HVAC system turn on and you’re ready for a cozy blast of warm air, but instead all you have is cool air blowing. That’s not what you want in the freezing weather!

There are a couple reasons why your heating equipment could be putting off cold air. Stevenson Service Experts Heating & Air Conditioning is here with some of them to help you locate the issue.

 

  • Thermostat

 

It may seem silly, but the thermostat is the first thing you want to look at. It’s the starting place for any furnace technician, too. Confirm the system is set to “auto as opposed to “on.” If the thermostat is set to “on” then your heating system will blow continuously, even when it isn’t really heating the air being produced, thus putting off cold air. Turning it to “auto” will make sure the heating equipment only blows when it’s actually heating the air to keep your home warm and comfortable.

 

  • Air Filter

 

Most air filters need to be changed once a month to keep them from becoming dirty and clogged. If your filters aren’t replaced often enough, the dirty air filter may impede airflow into your furnace. If this occurs, it can overheat your equipment, causing the system to stop heating as a safety measure.

 

  • Duct Work

 

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