7 Reasons Behind Your Blowing Cold Air & How To Fix Them

If the air smells like pumpkin latte everywhere, which means winter is here! As the weather gets biting cold, we want to make sure our homes are warm and comfy. Thus, we can already find long queues for a furnace tune-up in North Salt Lake. However, what can be worse than your furnace blowing out cold air instead of warm?

Well, there can be many reasons behind your furnace blowing cold air. Some could be grave, and some not so much.

7 Reasons Furnace is Blowing Cold Air

Please look at these seven most common reasons and simple ways to fix them.

1. Clogged Air Filters

Observe your furnace’s air filter if it’s covered in dust, grease, or soot. A clogged filter can also cause other issues such as long heating cycles and overheating. This overheating of the system can cause your furnace to blow cold air throughout the house.

Fortunately, you can immediately fix this matter by replacing the dirty air filter with a new one. That’s why most professional furnace services in Layton recommend changing air filters every 90 days.

2. Damaged Pilot Light

A furnace’s pilot light is designed to ignite the burners and enable them to produce heat. Here’s what you can do:

Locate your furnace’s reset toggle button and turn it OFF to deactivate the gas.

Wait a few times before turning the switch back ON to allow excess gas to exit the chamber. Now adjust the reset toggle to the Pilot setting to ensure gas reaches the pilot light. Now hold the reset button down while placing a match in front of the pilot light. Once the flame gets ignited, release the reset button, and it’s done!

3. Dirty Flame Sensor

A pilot flame sensor ensures a successful heating cycle by detecting the heat produced. However, if it has a lot of dirt and grim, the furnace will quickly lose heat and blow out cold air. You can instantly get this problem by blowing the flame sensor.

4. Clogged Condensate Lines

Condensate lines or drain lines are responsible for removing excess moisture. If the line is blocked, it can deactivate the burners causing your furnace to blow cold air.

5. Wrong Thermostat Settings

If your thermostat is set on “ON’, it will cause your furnace to continue even when it’s not producing heat. Toggle the switch to “AUTO” to ensure your furnace runs only during the standard heating process.

6. Depleted Gas Supply

If there isn’t enough gas supply to your furnace, it’s most likely unable to produce heat. Unfortunately, professional furnace services in Layton can only fix gas line problems.

7. Damaged Ductwork

Small holes and leaks in your ductwork can cause the warm air to escape before reaching you. Duct sealing and repair can help your ducts work more efficiently.
