Geothermal comfort in an outdoor package.

The York® Affinity™ YAP is a complete outdoor packaged system that provides quiet and efficient heating and cooling for the entire home. Its advanced components and features offer a level of comfort and savings that’s far greater than any ordinary system – at industry-leading efficiencies.


Geothermal heat pumps are much more efficient than traditional heating and cooling systems. The York® Affinity™ YAP is rated with an amazing 27.6 EER and 4.6 COP, which makes it one of the most efficient dual stage units on the market. Efficiency translates into savings.


One York® geothermal heat pump will provide heating and cooling for your entire home. A variety of sizes and configurations are available, so no matter your home or climate, a geothermal heat pump will work for you.

Cost effective

Geothermal heat pumps are so efficient that any added cost over traditional equipment is usually recovered in just a few years. And because they have a lifespan of 20-25 years, your investment will last longer and your return on investment will grow year by year.

Environmentally responsible

Since our units don't burn expensive, polluting fossil fuels, they're the most environmentally responsible options available today. Replacing a furnace and/or air conditioner with geothermal can minimize acid rain threats, air pollution, and the greenhouse effect.


No combustion or flames are used to operate a geothermal heat pump, making it a safe choice for your home and family. Our systems merely move heat to and from the ground rather than by burning natural gas, propane, or oil.

Affordable peace of mind

York® Affinity™ YAP units come with warranties up to 10 years for parts and labor allowances. Other options are available, so see your York® Contractor for details.

Dual capacity compressor

For superb efficiency and reliability dual capacity units utilize Scroll UltraTech™ compressors. All compressors are double isolation mounted for extra quiet operation.


Powerful Aurora controls offer two-way communication between components, industry leading operating logic, and thorough troubleshooting capabilities. An expansion board adds true energy monitoring as well as compatibility with our IntelliZone2 zoning system.

Blower motor

A variable speed ECM motor runs at only the speed needed for maximum efficiency and savings.

Internal Loop Pumps

The flow center is conveniently mounted within the cabinet, eliminating the need for any indoor loop piping. The loop pipes enter the unit through an opening in the bottom panel.

Aluminum Air Coil

YAP units feature aluminum air coils for durability and extended system life. Formicary corrosion is now a thing of the past.


The cabinet comes standard with a professional grade finish for long-lasting beauty and protection. The system is fully insulated for quiet operation with cleanable foil-backed insulation and is available in five dual capacity sizes (2-6 ton).


Our exclusive coaxial heat exchanger coating protects against condensation for temperatures below 50°F, extending its life.


This optional soft starter reduces start-up amperage by up to 60% of normal draw to reduce noise, eliminate light flicker, and increase compressor life.


All York® geothermal units utilize R-410A refrigerant, which is friendly to the environment.
