From their quiet furnaces to their high-efficiency air handlers, Dave Lennox Signature® Collection products represent the very finest in home heating, cooling and indoor air quality. Lennox's "Signature Collection" furnaces include the G71P (95% AFUE), G61V (94.6% AFUE) and the G60V (80% AFUE).

Innovative variable speed blower motors and SilentComfort® technology make the G71P, G61V and G60V three of the quietest furnaces you can buy - competitive furnaces can be up to eight times louder. The gradual acceleration and deceleration of the variable speed motor will help significantly reduce sound.
