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 built with variable speed motors. These motors alter their speed in relation to the amount of heat needed so you can save energy and decrease operating sounds. Now that we’re talking about operating sounds, SilentComfort™ technology is an additional key feature in these products, keeping your home warm, cozy and quiet – unlike some standard heating systems.
