Is your home not as warm and cozy as it should be? If your house is heated by a furnace system chances are your blower motor is not working and you need a replacement.
A blower motor takes warm air out of the furnace and circulates it around your home. This device is responsible for getting heat up to the temperatures set on the thermostat. If it is not operating efficiently, making you turn up your furnace it is going to cost you more money for little effect.
Replacing the blower motor could also save you a much larger furnace replacement cost. This review will help you choose the best furnace blower motor for your needs.
It is important to note, the blower motors in this review are different from the DRAFT inducer motors in your furnace. A draft inducer blower expels air and gasses from the heat exchanger unit out of your house through a chimney or vent. A blower motor, on the other hand, delivers warm air (or conditioned air) into your home.

What to Look For
Most blower motors stop working because their bearings fail. The blower wheel dropping out of balance usually causes this. It is important to replace this wheel at the same time as getting a new motor. Only the Daytons in this review include the blower wheel; which you will need to buy separately for the other motors.
Similarly, it is a very smart idea to get a new motor capacitor. Again, only the Daytons include a capacitor. When buying a new capacitor for the other motors, it is vital to get one with a capacitance rating (microfarad) that matches your motor.
Both blower wheels and capacitors can be bought separately on Amazon.
