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 are made possible by the models’ variable speed motors, which run at different speeds to better control air flow, minimize sound levels and cut down 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.
