@ 80% Efficient = 80% heat stays in home BUT 20% out chimney (20 cents p/ $1)
@ 96% Efficient = 96% heat stays in home BUT 4% out chimney (only 4 cents p/ $1)

1-Stage = Less Efficient operating at 100% every time
2-Stage = More Efficient operating at higher speeds only when required

Argument for a 2-stage furnace: A 2-stage furnaces give buyers the best balance between cost and value. They are more expensive to purchase initially than a 1-stage, but run more quietly and more efficiently. Air quality is also significantly improved in the home if your 2-stage furnace has a humidifier.

COMPARE TO: Auto Volume Control (AVC) where volume is increased with speed as needed.
