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

We know you desire an energy efficient furnace, which is why our Dave Lennox Signature Collection oil furnaces were built with variable speed motors. These motors alter their speed in relation to the amount of heat needed so you can reduce the amount of energy used and decrease operating sounds. Speaking of operating sounds, SilentComfort™ technology is also a key feature in this equipment, enabling your home to stay warm, cozy and quiet – unlike some typical heating systems.
