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 vary their speed in relation to the amount of heat needed to help you conserve energy and minimize operating sounds. Now that we’re talking about operating sounds, SilentComfort™ technology is another key feature in these products, enabling your home to stay warm, cozy and quiet – unlike some typical heating systems.
