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

We know you need an energy efficient furnace, which is why our Dave Lennox Signature Collection oil furnaces were made with variable speed motors. These motors vary their speed relative to the amount of heat needed to help you save energy and decrease operating sounds. Speaking of operating sounds, SilentComfort™ technology is also a key feature in these models, helping your home stay warm, cozy and quiet – unlike some traditional heating systems.
