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 are made possible by the units’ variable speed motors, which operate at different speeds to better control air flow, reduce sound levels and cut down energy costs. In addition, the sound – or lack thereof – on these oil furnaces is remarkable. SilentComfort technology allows heat to be produced and distributed without the loud noises characteristic of standard systems.
