Why Your Furnace Could be Blowing Cold Air

You notice your heating system turn on and you’re ready for a comfy blast of warm air, but instead all you have is cool air blowing. That’s not preferable 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 Heating & Air Conditioning is here with some of them to help you locate the culprit.

• Thermostat

It might seem silly, but the thermostat is where you should start. It’s the starting place for any furnace technician, too. Confirm the system is set to “auto and not “on.” If the thermostat is set to “on” then your HVAC system will blow continuously, even when it isn’t heating the air coming out, thus blasting 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

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

• Duct Work

If your duct work has leaks, connection problems, or was not designed correctly, it could let warm air from the furnace to escape out. This would not only cause your heating equipment to blow cold air, it could actually run up your energy bills since your heating system is heating non-living space, and will have to work overtime to keep your home comfortable.
