The Most Efficient and Quietest Oil Furnaces Available: Dave Lennox Signature® Collection 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 relative to the amount of heat needed which helps you save energy and soften operating sounds. Speaking of operating sounds, SilentComfort™ technology is another key feature in these products, keeping your home warm, cozy and quiet – unlike some traditional heating systems.
