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

We understand you need 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 based on the amount of heat needed which helps you conserve energy and decrease operating sounds. Since we’re on the topic of operating sounds, SilentComfort™ technology is an additional key feature in this equipment, enabling your home to stay warm, cozy and quiet – unlike some traditional heating systems.
