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

We understand you want an energy efficient furnace, which is why our Dave Lennox Signature Collection oil furnaces were built with variable speed motors. These motors vary their speed in relation to the amount of heat needed which helps you conserve energy and decrease operating sounds. Now that we’re talking about operating sounds, SilentComfort™ technology is also a key feature in these models, keeping your home warm, cozy and quiet – unlike some traditional heating systems.
