TWO STAGE COMFORT Why 2 Stage is Better
2 Stage controlled Furnaces allow you to use less energy during mild Spring and Fall temperatures. It’s like having a smaller furnace
installed just for spring and fall, then when winter hits you have the reserve power of the second heating stage to fight off the cold
weather. It also has the benefit of creating more even comfort temperatures.
Note: The Furnace will run a percentage longer to reach the room temperature so the ECM motors efficiency is key to getting the
most out of your Furnace.
