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 built with variable speed motors. These motors alter their speed relative to the amount of heat needed to help you conserve energy and soften operating sounds. Now that we’re talking about operating sounds, SilentComfort™ technology is an additional key feature in these models, keeping your home warm, cozy and quiet – unlike some standard heating systems.
