    How does a two-stage furnace work?

    A:

    Two-stage furnaces provide two different heating levels to keep a home comfortable regardless of its heating needs.

This lower level also reduces the temperature differences residents experience with a traditional furnace. On colder days, the unit operates at the second level, providing the needed additional heat.
