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 benefits are made possible by the units’ variable speed motors, which run at different speeds to better control air flow, minimize 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 typical in standard systems.
