The Most Efficient and Quietest Oil Furnaces Available: Dave Lennox Signature® Collection

You want an energy efficient furnace, which is why our Dave Lennox Signature Collection oil furnaces were built with variable speed motors. These motors vary their speed in relation to the amount of heat needed which helps you conserve energy and minimize operating sounds. Speaking of operating sounds, SilentComfort™ technology is an additional key feature in this equipment, helping your home stay warm, cozy and quiet – unlike some traditional heating systems.
