Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your furnace turn on and you’re expecting a comfortable 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 putting off cold air. Service Experts Heating & Air Conditioning is here with a few of them to help you find the problem.

 

  • Thermostat

 

It may feel silly, but the thermostat is the first thing you want to look at. It’s the first place any heating system technician will check, too. Confirm the system is set to “auto as opposed to “on.” If the thermostat is set to “on” then your furnace 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 system only blows when it’s actually heating the air to keep your home warm and cozy.

 

  • Air Filter

 

Typically air filters need to be changed monthly to avoid them from growing dirty and clogged. If air filters aren’t changed often enough, the dirty air filter may impede airflow into your heating system. If this happens, it can overheat your equipment, causing the equipment to stop heating as a safeguard.

 

  • Duct Work

 

If your duct work has leaks, connection problems, or was designed incorrectly, it could let warm air from the heating equipment to seep out. This would not only cause your heating system to produce 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.
