Learn about the Benefits of a Variable-Speed Furnace

The Dallas area’s fall and winter seasons brings with them a wide range of weather conditions. With a variable-speed furnace, you will enjoy stable, comfortable indoor temperatures in any season.

Advantages of Variable-Speed Furnaces

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

A variable-speed furnace isn’t limited to two speeds though, and can run at any speed within a set range, usually between 30 to 100 percent of its capacity. The microprocessor that controls its 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 own speed for maximum energy efficiency, a variable-speed motor creates optimal energy savings no matter how much heat or cooling your home needs at any given moment. A variable-speed furnace can meet about 80 percent of the average home’s needs while it runs at lower speeds, which results in overall lower energy bills.

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

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

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