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

We know you need an energy efficient furnace, which is why our Dave Lennox Signature Collection oil furnaces were constructed with variable speed motors. These motors vary their speed in relation to the amount of heat needed so you can save energy and minimize operating sounds. Speaking 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.
