Diamond Ultra High Efficiency (PXD-V)
The York Diamond ULTRA high-efficiency gas furnace eliminates the trade-off of economy for dependable, reliable performance.  Or the choice between quiet operation and even, whole-house heating.  At up to 94% AFUE, a new York Diamond ULTRA gas furnace allows customers to slash operating costs as much as 60%, while keeping operating sounds to a whisper.  These furnaces circulate more air throughout the home for longer periods of time, reducing stratification from room-to-room and floor-to-floor.  Longer run cycles can improve air quality by improving air filtration.  The secret is York's two-stage, variable-speed furnace engineering.  It's a York engineering achievement providing unparalleled home comfort and operational economy.
