Why Your Furnace Could be Blowing Cold Air

You hear your HVAC system start up and you’re expecting a comfortable blast of warm air, but instead all you feel is cool air blowing. That’s not preferable in freezing temperatures!

There are a few reasons why your heating system could be blowing cold air. Winnipeg Supply Service Experts is here with some of them to help you detect the culprit.

    • Thermostat

It might sound 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. Verify the system is set to “auto as opposed to “on.” If the thermostat is set to “on” then your HVAC system will blow constantly, even when it is not actually heating the air being produced, thus blowing cold air. Changing it to “auto” will make sure the heating system only blows when it’s actually heating the air to keep your home warm and comfy.

    • Air Filter

Typically air filters need to be changed every month to avoid them from getting dirty and clogged. If your filters aren’t replaced often enough, the soiled air filter may restrict 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 includes leaks, connection troubles, or was designed incorrectly, it could let warm air from the furnace to seep out. This would not only cause your heating system to produce cold air, it could actually run up your energy bills since your furnace is heating non-living space, and will have to work more to keep your home comfortable.
