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 features stand out thanks to the products’ variable speed motors, which work at different speeds to better control air flow, minimize sound levels and decrease energy costs. Additionally, the sound – or lack thereof – on these oil furnaces is outstanding. SilentComfort technology produces and distributes heat without the loud noises characteristic of standard systems.
