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

Dave Lennox Signature Collection oil furnaces are defined by their quiet and efficient operation. These benefits would not be possible without the products’ variable speed motors, which work at different speeds to better control air flow, reduce sound levels and lower energy costs. Have you heard? The sound – or lack thereof – on these oil furnaces is outstanding. SilentComfort technology enables heat to be produced and distributed without the loud noises characteristic of standard systems.
