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

We know you want an energy efficient furnace, which is why our Dave Lennox Signature Collection oil furnaces were made with variable speed motors. These motors adjust their speed based on the amount of heat needed to help you conserve energy and minimize operating sounds. Now that we’re talking about operating sounds, SilentComfort™ technology is an additional key feature in these products, helping your home stay warm, cozy and quiet – unlike some standard heating systems.
