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 features stand out thanks to the products’ variable speed motors, which operate at different speeds to better control air flow, limit sound levels and cut down energy costs. In addition, the sound – or lack thereof – on these oil furnaces is outstanding. SilentComfort technology allows heat to be produced and distributed without the loud noises commonly associated with standard systems.
