This May Be Why Your Furnace Blows Cool Air in Lusby, MD

When your furnace produces cold air during the cooler months, it’s hard to remain comfortable in your home. Here are some factors that can make your furnace blow cold air in Lusby, MD.

Dirty Air Filter

Dust, pollen and other particles gradually accumulate on your air filter. Without regular maintenance and consistent filter replacement, your air filter becomes clogged and blocks the airflow. Insufficient airflow may cause the furnace to malfunction, or it might shut off altogether.

Low Gas Supply

Gas furnaces can’t heat the air without a steady fuel supply. If your pilot light keeps going out and your air isn’t warming up, this may indicate an inadequate fuel supply or problems with the gas line. Always call an expert for help with gas issues.

Clogged Condensate Lines

Condensate lines drain the excess moisture that your furnace may produce. When the lines get clogged, your pilot light might go out, making it impossible for your system to heat the air. Your furnace may shut off because it can’t safely operate without drainage.

Leaky Ductwork

Hot air may escape through leaks in your ductwork, giving the impression that your HVAC system is malfunctioning. This heat loss also forces your furnace to work harder and inflates energy bills. Fortunately, HVAC experts can inspect your ductwork and repair leaks to keep air inside the system.

Wrong Thermostat Setting

Check your thermostat to see if it’s set to “On” instead of “Auto.” The “On” setting makes your furnace run continuously, releasing cooler air when it doesn’t generate heat. Setting your furnace to “Auto” ensures it only runs when actively heating the air.
