Why Is My Furnace Blowing Cold Air in Conroe, TX?

When the weather turns cold in Conroe, TX, you expect your furnace to heat your home. However, issues can arise with your heating system. As a result, you may find yourself with a furnace that blows cold air instead. Here are some possible reasons your furnace is blowing cold air throughout your home in Conroe, TX, and what to do about it:

Dirty Air Filter

Dirty air filters restrict airflow, causing a furnace to overheat. A safety mechanism can eventually shut down the burners. This results in the circulation of unheated air throughout your home.

Thermostat Issues

A malfunctioning or incorrectly set thermostat can cause your furnace to blow cold air. The result is a home that’s not as warm.

Fuel Source Issues

If your gas furnace isn’t getting the fuel source it needs to generate heat, it’ll simply blow cold air. An issue with your gas line could be the reason for a compromised fuel source.

Faulty Flame Sensor

Do you have a gas furnace? The flame sensor detects whether a flame is present with the pilot light. When this sensor doesn’t sense a flame, it’ll shut off the gas supply, causing the furnace to blow cold air.

Leaky Ducts

Ductwork issues are a common reason for a furnace to blow cold instead of warm air. The warm air created by the furnace escapes the duct system through separate joints or holes in the ducting while cold air seeps in to replace it.

Having a furnace blowing cold instead of warm air is extremely frustrating during the winter months. Dirty air filters, faulty thermostats, malfunctioning components and system leaks are all possible reasons for your furnace to blow cold air.
