Why Your Furnace Could be Blowing Cold Air

You notice your HVAC system start up and you’re anticipating a cozy blast of warm air, but instead all you have is cool air blowing. That’s no good in freezing temperatures!

There are a few reasons why your heating equipment could be putting off cold air. A1 Chesney Service Experts Heating & Air Conditioning 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. Confirm the system is set to “auto instead of “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. Turning 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 getting dirty and clogged. If they aren’t replaced often enough, the clogged air filter may obstruct airflow into your furnace. 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 issues, or was not designed correctly, it could allow warm air from the furnace to seep out. This would not only cause your furnace to produce cold air, it could significantly run up your heating bills since your heating system is heating non-living space, and will have to work overtime to keep your home at the desired temperature.
