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

We understand you desire an energy efficient furnace, which is why our Dave Lennox Signature Collection oil furnaces were made with variable speed motors. These motors adjust their speed based on the amount of heat needed which helps you reduce the amount of energy used and minimize operating sounds. Now that we’re talking about operating sounds, SilentComfort™ technology is another key feature in this equipment, helping your home stay warm, cozy and quiet – unlike some standard heating systems.
