Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You notice your HVAC system start up and you’re anticipating a comfy blast of warm air, but instead all you have is cool air blowing. That’s not what you want when it’s cold outside!

There are a few reasons why your heating equipment could be putting off cold air. A1 Chesney Service Experts is here with a couple of them to help you find the problem.

 

  • Thermostat

 

It might 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 and not “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 blasting cold air. Changing it to “auto” will make sure the heating equipment only blows when it’s really heating the air to keep your home warm and comfy.

 

  • Air Filter

 

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

 

  • Duct Work

 

If your duct work includes leaks, connection problems, or was not designed correctly, it could permit 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 energy bills since your heating system is heating non-living space, and will have to work overtime to keep your home at the desired temperature.
