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

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 in relation 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 products, enabling your home to stay warm, cozy and quiet – unlike some typical heating systems.
