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 would not be possible without the products’ variable speed motors, which run at different speeds to better control air flow, reduce sound levels and decrease energy costs. Additionally, the sound – or lack thereof – on these oil furnaces is remarkable. SilentComfort technology produces and distributes heat without the loud noises typical in standard systems.
