Why is My Furnace Blowing Cold Air When the Thermostat is Set to Heat?

If you're experiencing a situation where your furnace is blowing cold air despite the thermostat being set to heat, it's essential to identify the cause and address it promptly. At North Coast Thermal, we've encountered numerous cases of faulty furnaces in North Ridgeville, Elyria, Avon, and other surrounding areas. In this blog post, we'll delve into the possible reasons behind this issue and provide guidance on how to resolve it.

Possible Causes of Cold Air from Furnace

There are several reasons why your furnace might be blowing cold air when the thermostat is set to heat. Some of the most common causes include:

• Pilot light issues: A faulty pilot light can prevent the furnace from igniting, resulting in cold air being blown.
• Thermostat problems: A malfunctioning thermostat can cause the furnace to blow cold air, even when set to heat.
• Dirty or clogged air filters: Dirty air filters can restrict airflow, leading to cold air being blown from the furnace.
• Leaky ducts: Leaks in the ductwork can cause heated air to escape, resulting in cold air being blown from the vents.
