The Most Efficient and Quietest Oil Furnaces Available: Dave Lennox Signature® Collection We understand you want an energy efficient furnace, which is why our Dave Lennox Signature Collection oil furnaces were constructed with variable speed motors. These motors alter their speed in relation 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 this equipment, enabling your home to stay warm, cozy and quiet – unlike some typical heating systems.
