The Most Efficient and Quietest Oil Furnaces Available: Dave Lennox Signature® Collection You need 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 reduce the amount of energy used and soften operating sounds. Now that we’re talking about operating sounds, SilentComfort™ technology is also a key feature in this equipment, enabling your home to stay warm, cozy and quiet – unlike some traditional heating systems.
