5 benefits of a variable speed fan. Basics of variable speed air conditioning. Saves energy and money. The initial cost of a furnace with an ecm will be higher than a traditional furnace but the typical payback on a variable speed furnace is just 4 to 5 years.

Variable speed blower motor s. The best news a variable speed furnace motor is 80 85 more efficient than a standard furnace motor. With a smart thermostat it will turn the furnace on or off based on temperature. This n ew technology has an ecm motor with a speed controller.

Variable speed compressors work differently. Variable speed furnace unlike a single stage furnace and 2 stage furnace a variable speed furnace doesn t actually refer to the number of stages your furnace goes through to provide heat. As a result they run for much longer cycles than single stage ac units. In order to maintain an indoor temperature that matches the setting on your thermostat they operate continuously at less than 100 capacity often as low as 25 or 30 capacity.

But with variable speed correct me if i m wrong but the fan is constantly modulating faster or slower depending on what temperature the thermostat tells it. A variable speed blower motor can operate at various speeds to precisely control the amount of airflow throughout your home. The advantages don t stop there however variable speed technology has many benefits that make it a great choice for heating and cooling your home. The variable speed furnace delivers the proper amount of airflow based on the heating and cooling needs of your home.

So if you are going to upgrade from a 90 to a 96 efficient furnace make sure it has a variable speed furnace motor and you could enjoy energy savings of up to 400 a year. I t is more like a continuous blowing approach it provides the precise heat or cooling output your home needs at any given time day or night. Rather it refers to the fan motor in the furnace. A variable speed ac s longer run times and lower speeds means cool air is steadily pushed throughout the whole house to provide even temperatures.

In the winter a variable speed blower motor may alleviate the cold. Unlike conventional fan motors a variable speed blower motor runs at different speeds to precisely control the flow of heated or cooled air throughout your home. The system also accounts for blocked vents and dirty furnace filters and adjusts fan speed as needed to compensate. It accounts for the amount of air in circulation for precision airflow.

It can also use multistages i think up to 3 with nest to turn it to high med low i think. In variable speed furnaces the fan motor can move at different speeds to control the amount of heated. A variable speed unit the grey line in the graphic runs longer but at a lower capacity maybe between 30 and 50 to maintain the set temperature. Variable speed fan motor technology.

Benefits of a variable speed ac. When compared to one and two stage systems variable speed technology offers consumers a step up in both comfort and performance.
