Although cold weather is not a year-round issue in north-central Florida, you will have plenty of nights when you need your heating system to be reliable. If you’re having major problems with the system, such as your furnace blowing cold air, it may be time to enlist the help of a professional.

At Fast Air Heating & Cooling, our licensed technicians have experience working on various furnace types. Learn more about the furnace troubleshooting steps you can take and when it’s time to reach out to a professional. 

The System Needs Time

A working furnace will frequently blow some cold air when it initially begins running. When the furnace sits idle for several weeks or months, it may take longer to generate warmth the first time you turn it on. Night-time low temperatures here rarely fall below 50 degrees outside of the winter months. If the area has a cold snap in spring or autumn, your heating system might take several minutes to warm up the first time you need it.

When the furnace initially turns on, the air in the ductwork matches the ambient temperature, and it takes a few minutes to force the warmth from the heater through the ducts. Once that happens, you should notice a steady stream of heat coming from the supply vents. 

Your System’s Airflow Is Blocked

One of the most common reasons why a furnace blows cold air is because of blockages.

If you have a clogged air filter, it prevents the system from cooling itself as it operates, leading to overheating. When furnaces overheat, they might shut down, and cool air will come out of the vents because the fan continues running.

The Ductwork Is Leaking

Leaky ducts struggle to move the heater’s warm air to the supply vents in the house. When the warm air leaks into attics and inside walls, it doesn’t help your comfort level inside the living areas.

Ductwork with damage or holes can also lead to a significant increase in energy costs. If you’ve noticed a jump in your energy bill, leaky ductwork could be to blame. Hissing or whistling sounds from inside your attic or walls could be a sign that you have leaky ducts. Our team of experts can inspect the ducts and determine the most effective repair approach.

Check the Status of the Thermostat

The thermostat controls the temperature of the system. If it is set incorrectly, it could explain why your furnace is blowing cold air.

In Morriston, FL, residents run their air conditioners far more often than their furnaces. Your system might be set to cool only, and you might have forgotten to reset it to heat before a cold night arrives. Check the settings on the thermostat if your system is blowing nothing but cool air.

A bad thermostat can also cause the heater to blow only cool air. Our repair professionals can test your thermostat and determine whether it needs to be replaced.
