Furnace Blower Motor | AC Blower Motor
Blower Fan Motors are pretty much a cut and dry product inside your furnace or air handler unit of your HVAC system. The main purpose of the fan motor is to take the return air from your home, and increase the velocity to a predetermined volume, and disperse it through your home duct system. The thermostat in your furnace will detect when the furnace becomes hot and in turn, switches on the blower fan.
Blower motors consist of a motor and impeller and the airflow is blasted when the HVAC system is turned on. They range in power from about 1/8 th. horsepower to 3/4 horsepower and typically have a 1200 RPM. Motors come in many different types, such as Split Phase and 3 Phase.
If you plan to replace your blower motor yourself, it is important that you do the proper research in advance to identify the exact motor you need. Typically, it is better to have an experienced Heating and Air Conditioning contractor replace it for you, but it is not out of the realm of normal handyman parts replacement. In fact, if you feel you could install an electric motor into a ceiling fan or some other electrical device, you can probably handle a furnace blower motor as well.
