There can be many reasons for this problem. This month, Appalachian Heating & Air will dive into answering the question, “Why does a furnace blow cold air?”


Furnace Needs Time to Warm Up

If your furnace immediately starts blowing cold air, give it time. Heaters typically need a minute or two to reach their full potential in homes and businesses across Martinsburg, WV.


Relight the Pilot Light

The pilot light is a small light that burns continuously to ignite your furnace. In the event of a draft, this light can burn out. Models that are 20 years old and older typically do not have a pilot light. For many property owners in Martinsburg, WV, relighting the pilot light is an easy process.


The Gas Supply is Weak

Furnaces often require a steady supply of gas to produce heat. With an insufficient gas supply, your Martinsburg, WV, furnace will deactivate as a safety measure.


Flame Sensors Contain Grime and Dirt

Furnaces without pilot lights contain flame sensors. If the flame rod contains dirt or grime, the burner can shut off. Martinsburg, WV, homeowners can efficiently resolve this issue by cleaning the flame sensor.


Damaged Ductwork

Cold air can easily enter the ducts. If you notice any cracks or holes in your ductwork in Martinsburg, WV, call us. Ductwork damage can happen in the summer months, resulting in insufficient home cooling. If you are in the market for ductwork repair, you can trust Appalachian Heating & Air.
