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 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 decrease energy costs. In addition, the sound – or lack thereof – on these oil furnaces is amazing. SilentComfort technology enables heat to be produced and distributed without the loud noises commonly associated with standard systems.
