Variable speed furnace blower.

This n ew technology has an ecm motor with a speed controller. Better airflow control has several benefits. A variable speed blower motor can operate at various speeds to precisely control the amount of airflow throughout your home. Variable speed furnaces generally only run at high capacity during the coldest portion of the heating season so they are efficient.

The air quality is improved in your home with a variable speed blower. Single speed blower motors function at full power or not at all switching off and on to regulate your indoor temperatures. Variable speed furnaces contain an ecm electronically commutated motor blower motor which allows the furnace to operate at higher efficiency levels. In contrast variable speed models operate at a range of levels depending on your household s heating needs at the moment in the summer they work to cool your home too.

These speeds are used by a contractor to adjust airflow to the proper amount. The term variable speed furnace is used to describe furnaces that have a variable speed blower motor. A variable speed furnace blower motor is a step above a multi speed blower. Furnaces without variable speed technology use a simple motor with multiple speed settings.

They are dc motors that use a built in inverter and magnet rotor delivering better energy efficiency than furnaces with ac motors. I t is more like a continuous blowing approach. The term variable speed actually refers to the blower motor inside the furnace or air handler. The units use nearly six times less energy when compared with single speed systems.

In the winter a variable speed blower motor may alleviate the cold air blow often associated with single speed furnaces or air handlers. It provides the precise heat or cooling output your home needs at any given time day or night. When upgrading your furnace consider adding a variable speed furnace blower motor. Ecm s are dc motors that function using a built in inverter and a magnet rotor and as a result are able to achieve greater efficiency than most ac motors.

It s an electronically commutated motor or ecm. It can improve the efficiency of your heating system while making your home more comfortable.
