Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your HVAC system kick on and you’re anticipating a cozy blast of warm air, but instead all you have is cool air blowing. That’s no good in the freezing weather!

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

 

  • Thermostat

 

It could sound silly, but the thermostat is the first thing you want to look at. It’s the starting point for any heating technician, too. Confirm the system is set to “auto and not “on.” If the thermostat is set to “on” then your heating system will blow constantly, even when it isn’t really heating the air coming out, thus blowing cold air. Flipping it to “auto” will make sure the furnace only blows when it’s truly 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 they aren’t replaced often enough, the clogged air filter may obstruct airflow into your furnace. If this takes place, it can overheat your system, causing the furnace to stop heating as a safeguard.

 

  • Duct Work

 

If your duct work contains leaks, connection issues, or was not designed properly, it could allow warm air from the furnace to seep out. This would not only cause your heating equipment to blow cold air, it could actually run up your utility bills since your heating equipment is heating non-living space, and will have to work harder to keep your home comfortable.
