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

Dave Lennox Signature Collection oil furnaces have two outstanding qualities: quiet and efficient operation. These features stand out thanks to the models’ variable speed motors, which operate 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 typical in standard systems.
