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 constructed with variable speed motors. These motors adjust their speed relative to the amount of heat needed which helps you save energy and soften operating sounds.
