The Affinity is one of the quietest series ever offered by York.
Innovative design reduces the sound dramatically:

• High-efficiency compressors are the quietest type of compressor available.
• Quieter compressors are isolated behind an advanced composite material further reducing transmitted compressor noise.
• Advanced fan design for smoother air flow and reduced noise.
• The QuietDrive™ System features a swept-wing fan design, isolated compressor compartment, composite base pan, and high-efficiency compressor technology that provides quieter operation than conventional systems.
• Two-stage compressor technology that provides up to 4x quieter operation and 60% more energy efficient operation.
• A composite base pan distributes and dampens sound.

The Affinity is so quiet, you may never notice it running.
* For every 3 decibels quieter, sound power is cut 50%!
