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 operate at different speeds to better control air flow, limit sound levels and lower energy costs. In addition, the sound – or lack thereof – on these oil furnaces is remarkable. SilentComfort technology produces and distributes heat without the loud noises commonly associated with standard systems.
