Why Your Furnace Could be Blowing Cold Air

You hear your furnace start up and you’re ready for a comfy blast of warm air, but instead all you feel is cool air blowing. That’s not what you want in the freezing weather! 

There are a handful of reasons why your heating equipment could be giving off cold air. Rob's Albertan Service Experts is here with some of them to help you locate the issue. 

  • Thermostat 

It might seem silly, but the thermostat is where you should start. 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 heating system will blow constantly, even when it is not actually heating the air coming out, thus putting off cold air. Changing it to “auto” will make sure the heating equipment only blows when it’s actually heating the air to keep your home warm and cozy. 

  • Air Filter 

The majority of air filters need to be changed once a month to prevent them from becoming dirty and clogged. If air filters aren’t changed often enough, the clogged air filter may restrict airflow into your heating system. If this happens, it can overheat your furnace, causing the equipment to stop heating as a safety measure. 

  • Duct Work 

If your duct work includes leaks, connection troubles, or was not designed correctly, it could let warm air from the furnace to escape out. This would not only cause your heating system to produce 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 at the desired temperature. 

There are several other reasons that your heating equipment could give off cold air.
