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

We know you desire an energy efficient furnace, which is why our Dave Lennox Signature Collection oil furnaces were constructed with variable speed motors. These motors alter their speed based on the amount of heat needed so you can conserve energy and minimize operating sounds. Since we’re on the topic of operating sounds, SilentComfort™ technology is also a key feature in these products, keeping your home warm, cozy and quiet – unlike some standard heating systems.
