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

Dave Lennox Signature Collection oil furnaces are known for their quiet and efficient operation. These benefits are made possible by the models’ variable speed motors, which work at different speeds to better control air flow, reduce sound levels and lower energy costs. Additionally, the sound – or lack thereof – on these oil furnaces is remarkable. SilentComfort technology enables heat to be produced and distributed without the loud noises typical in standard systems.
