What is A Blower Motor?

If you’ve ever wondered how the hot air that your furnace makes gets to you, then you can thank your blower motor. The blower motor is a critical component of the furnace that takes care of turning a fan that will then circulate warm air from your furnace into your home. Without a working blower motor, you furnace will simply not heat your home.

There are two types of blower motors that you could have. Your home furnace will have either a variable or single speed blower motor. While both will keep you warm and comfortable, they function in different ways. A single seed motor will turn on and off depending on the setting of your thermostat. While a variable speed blower will change speeds to help keep a consistent flow of warm air through your home.
