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

You want 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 based on the amount of heat needed so you can conserve energy and decrease operating sounds. Now that we’re talking about operating sounds, SilentComfort™ technology is another key feature in these models, helping your home stay warm, cozy and quiet – unlike some standard heating systems.
