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 made with variable speed motors. These motors alter their speed based on the amount of heat needed to help you save energy and soften operating sounds. Now that we’re talking about operating sounds, SilentComfort™ technology is another key feature in these models, keeping your home warm, cozy and quiet – unlike some typical heating systems.
