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 models’ variable speed motors, which work at different speeds to better control air flow, reduce sound levels and lower energy costs. In addition, the sound – or lack thereof – on these oil furnaces is amazing. SilentComfort technology allows heat to be produced and distributed without the loud noises typical in standard systems.
