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 not what you want in the freezing weather!

There are a few reasons why your heating equipment could be putting off cold air. Stevenson Service Experts is here with some of them to help you find the issue.

 

  • Thermostat

 

It may seem 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. Make sure 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 coming out, thus blowing cold air. Turning it to “auto” will make sure the heating equipment only blows when it’s truly heating the air to keep your home warm and comfortable.

 

  • Air Filter

 

Most air filters need to be changed once a month to avoid them from getting dirty and clogged. If your filters aren’t replaced often enough, the clogged air filter may impede airflow into your furnace. If this happens, it can overheat your equipment, causing the furnace 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 furnace to blow cold air, it could significantly 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.
