Learn about the Benefits of a Variable-Speed Furnace

The Indianapolis area’s fall and winter seasons bring a wide range of weather conditions. With a variable-speed furnace, you can enjoy stable, comfortable indoor temperatures in any season.

Advantages of Variable-Speed Furnaces

The blower fan motors in older, mid-efficiency furnaces have only two speed settings: high and low. Most of the time, the lower, more energy-efficient setting is enough to keep a home comfortable, so the furnace kicks into high only when it needs to meet higher-than-normal heating or cooling demands.

A variable-speed furnace isn’t limited to two speeds. It can run at any speed within a set range, usually between 30 to 100 percent of its capacity. The microprocessor that controls the motor can select precisely the most energy-efficient speed for any heating or cooling demand.

Greater Savings and Comfort

Thanks to its ability to fine tune its speed for maximum energy efficiency, a variable-speed motor provides optimal energy savings no matter how much heat or cooling your home needs at any given moment. A variable-speed furnace can meet around 80 percent of the average home’s needs while running at lower speeds, which results in overall lower energy bills.

A conventional furnace pushes out a large amount of air quickly before shutting off, often causing uncomfortable temperature fluctuations. A variable-speed furnace runs for longer cycles at lower speeds. This means it heats your home gently, preventing temperature swings and eliminating cold and hot spots. In summer, the motor’s longer cycles give your A/C more time to reduce humidity, improving your comfort.

Longer cycles mean your home’s air is drawn through the furnace air filter more often. This results in better air filtration and higher indoor air quality.

A motor running on a lower speed makes less noise, so you can enjoy a quieter home. Lower operational speeds also place less wear and tear on the motor, helping it last longer.
