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

You desire an energy efficient furnace, which is why our Dave Lennox Signature Collection oil furnaces were made with variable speed motors. These motors vary their speed relative to the amount of heat needed so you can reduce the amount of energy used and soften operating sounds. Since we’re on the topic of operating sounds, SilentComfort™ technology is also a key feature in these models, keeping your home warm, cozy and quiet – unlike some standard heating systems.
