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 units’ variable speed motors, which operate at different speeds to better control air flow, minimize sound levels and decrease energy costs. Additionally, the sound – or lack thereof – on these oil furnaces is amazing. SilentComfort technology produces and distributes heat without the loud noises characteristic of standard systems.
