A 2 stage furnace is like having a superhero furnace with a secret identity! Most of the time, it’s running on low power, saving energy and keeping your home at a comfortable temperature. But when the temperature outside drops and your home needs a little extra warmth, the furnace activates its high power setting, just like a superhero revealing their true identity to save the day! With this type of furnace, you’ll have a steady flow of warm air and energy savings, making it a win-win for you and your home.
