Why Your Furnace Could be Blowing Cold Air

You listen to your furnace start up and you’re expecting a comfortable blast of warm air, but instead all you get is cool air blowing. That’s no good in freezing temperatures!

There are a few reasons why your heating equipment could be blowing cold air. Service Experts Heating, Air Conditioning & Plumbing is here with some of them to help you locate the culprit.

    • Thermostat

It may seem 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 and not “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. Turning it to “auto” will make sure the heating equipment only blows when it’s truly heating the air to keep your home warm and cozy.

    • Air Filter

Most air filters need to be changed every month to keep them from becoming dirty and clogged. If your filters aren’t replaced often enough, the dirty air filter may obstruct airflow into your heating equipment. If this occurs, it can overheat your system, causing the equipment to stop heating as a safety measure.

    • Duct Work

If your duct work has leaks, connection issues, or was not designed properly, it could allow warm air from the furnace to leak out. This would not only cause your heating system to give off cold air, it could seriously run up your heating 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 many other reasons that your heating system could give off cold air. Call Service Experts Heating, Air Conditioning & Plumbing today and we’ll send a technician to diagnose your malfunction and get your home warm and comfortable again in no time.
