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 features stand out thanks to the products’ variable speed motors, which work at different speeds to better control air flow, limit 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.
