The Most Efficient and Quietest Oil Furnaces Available: Dave Lennox Signature® Collection

We know you desire 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 based on the amount of heat needed to help you save energy and minimize operating sounds.
