Variable Speed Fan Hvac

It accounts for the amount of air in circulation for precision airflow.

Variable speed fan hvac.

Variable speed technology can also apply to the type of blower motor located in the air handler or gas furnace. In variable speed furnaces the fan motor can move at different speeds to control the amount of heated. Rather it refers to the fan motor in the furnace. 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.

It can also use multistages i think up to 3 with nest to turn it to high med low i think. 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. 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. 5 benefits of a variable speed fan.

With a smart thermostat it will turn the furnace on or off based on temperature. As a result they run for much longer cycles than single stage ac units. 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. 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.

In the winter a variable speed blower motor may alleviate the cold. The system also accounts for blocked vents and dirty furnace filters and adjusts fan speed as needed to compensate. A variable speed blower motor can operate at various speeds to precisely control the amount of airflow throughout your home. The air quality is improved in your home with a variable speed blower.

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. 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. How does it work. When compared to one and two stage systems variable speed technology offers consumers a step up in both comfort and performance.

Benefits of a variable speed ac. 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. Basics of variable speed air conditioning. The best news a variable speed furnace motor is 80 85 more efficient than a standard furnace motor.

Variable speed compressors work differently. 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. Saves energy and money. Variable speed fan motor technology.

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. This n ew technology has an ecm motor with a speed controller.
