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 made with variable speed motors. These motors alter their speed in relation to the amount of heat needed to help you save energy and minimize operating sounds. Since we’re on the topic of operating sounds, SilentComfort™ technology is also a key feature in these products, keeping your home warm, cozy and quiet – unlike some typical heating systems.
