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

We understand you need an energy efficient furnace, which is why our Dave Lennox Signature Collection oil furnaces were made with variable speed motors. These motors alter their speed based on the amount of heat needed to help you conserve energy and minimize operating sounds. Now that we’re talking about operating sounds, SilentComfort™ technology is another key feature in these products, keeping your home warm, cozy and quiet – unlike some standard heating systems.
