A modulating furnace will be even more energy-efficient if it's paired with a variable-speed (or multi-speed) blower motor. However, the technology that allows a modulating furnace to operate at variable capacities raises the cost of the equipment considerably. This increased precision results in a home that is more consistently heated, both in different areas of the home and over time.
