Springfield PA Heating Question: What Is a Variable Speed Blower on a Forced Air Heating System?

As its name implies, a variable speed blower (or fan) can move at varying speeds. As opposed to single-speed fans, a variable speed blower can adjust its speed based on the heating or cooling needs of your home. This allows it to enjoy energy efficiencies that aren’t available to single-speed blowers. If your home needs just a small amount of heat added to it, the fan can turn on slowly to gradually adjust the temperature. Below we’ve outlined some of the benefits of having a variable speed blower in your Springfield PA heating system.

Greater Comfort

Because a different speed settings they can distribute heated air more evenly across your house. This results in increase in general comfort in your home. With the added speeds, your heating system is more precise and can regulate the airflow throughout your house.

Greater Efficiency

With more fan speeds, your heating system isn’t stopping and starting as often. The process of starting the air moving and starting the fan consumes a large amount of energy. By allowing the fan to operate longer at lower speeds, you can avoid that costly startup period. In general, variable speed systems use about 2/3rd less energy.

Cleaner Air

When the system isn’t running, the fan is constantly moving. This allows your system to circulate more air through your air filter and capture more particles. It also doesn’t allow dust or pollen to settle in your ducts which can cause irritation for people who suffer from allergies or asthma.

Quieter

Having multiple speeds allows the fan to operate at slower speeds more often. This reduced speed doesn’t create as much noise as a fan that can only run at full speed.
