Why Your Furnace Could be Blowing Cold Air

You notice your HVAC system kick on and you’re ready for a cozy blast of warm air, but instead all you get is cool air blowing. That’s not what you want in the freezing weather!

There are a couple reasons why your heating system could be blowing cold air. Wesley Wood Service Experts is here with a few of them to help you locate the culprit.

• Thermostat

It might sound silly, but the thermostat is the first place you should check. It’s the starting point for any heating technician, too. Make sure the system is set to “auto as opposed to “on.” If the thermostat is set to “on” then your furnace will blow continually, even when it isn’t heating the air coming out, thus putting off 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 cozy.

• Air Filter

Most air filters need to be changed every month to avoid them from growing dirty and clogged. If your filters aren’t changed often enough, the soiled 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 safety measure.

• Duct Work

If your duct work contains leaks, connection issues, or was not designed correctly, it could let warm air from the heating system to leak out. This would not only cause your furnace to produce cold air, it could significantly run up your heating bills since your furnace is heating non-living space, and will have to work more to keep your home warm.
