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 constructed 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 soften operating sounds. Since we’re on the topic of operating sounds, SilentComfort™ technology is another key feature in these products, keeping your home warm, cozy and quiet – unlike some traditional heating systems.
