More About York

York is a manufacturer of residential and commercial HVAC equipment, including central air conditioners, heat pumps, gas furnaces, and air handlers, with a product history dating to 1874. Founded in York, Pennsylvania, York is now part of Johnson Controls and produces equipment across efficiency tiers from DOE-minimum single-stage models to high-efficiency variable-capacity systems. York's residential lineup includes the Affinity Series, LX Series, and entry-level lines covering heat pumps and air conditioners from 14.3 SEER2 through 19 SEER2. Select York products qualify for ENERGY STAR and are eligible for Inflation Reduction Act federal tax credits and rebates.

Product Lines

York Affinity Series Heat Pumps (YZV)

The York YZV Affinity Series is a variable-capacity communicating heat pump rated at 19 SEER2, using a variable-speed inverter compressor that adjusts capacity to match the home's load. The YZV qualifies for ENERGY STAR certification and may be eligible for IRA federal tax credits and utility rebates.

York LX Series Heat Pumps (YH6, YH2F)

York LX Series heat pumps cover the ENERGY STAR efficiency tier with two-stage (YH6, 16 SEER2) and 1-and-2-stage (YH2F, 15.2 SEER2) configurations. Both meet ENERGY STAR and CEE Tier 1 requirements and are eligible for IRA incentives. The YH6 provides reduced sound and tighter temperature control over single-stage models.

York Entry-Level Heat Pumps (YH2E) and Air Conditioners (YC2E, YC2F)

York entry-level models (YH2E heat pump 14.3 SEER2; YC2E air conditioner 14.3 SEER2; YC2F up to 17.5 SEER2) meet 2023 DOE minimum efficiency standards. The YH2E is designed for straightforward residential replacement projects. The YC2F steps up to two-stage capacity for larger tonnage and is ENERGY STAR rated.

York Residential Gas Furnaces

York residential gas furnaces are available in 80% and 90% AFUE configurations. High-efficiency York furnaces with variable-speed blowers and two-stage gas valves provide tighter temperature control and lower fuel use compared to single-stage, constant-speed models. York furnaces match with York split system equipment for AHRI-rated system combinations.

Why Contractors Specify York

HVAC contractors specify York because the product line covers the full range of residential efficiency tiers from DOE-minimum replacements through ENERGY STAR variable-capacity systems eligible for IRA federal tax credits. York LX Series and Affinity Series heat pumps qualify for ENERGY STAR and CEE Tier 1, giving contractors access to incentive-eligible products for customers pursuing IRA rebates. York is part of Johnson Controls. York furnaces and air handlers are designed to match with York split system equipment, simplifying system selection and supporting AHRI-rated matched system efficiency documentation.

How to Choose a York Product

The most important decision variable is the application efficiency target: DOE-minimum replacement, ENERGY STAR replacement, or high-efficiency variable-capacity installation. For DOE-minimum work, the YH2E (14.3 SEER2) and YC2E (14.3 SEER2) cover standard replacement. For ENERGY STAR-qualifying installations, the YH2F (15.2 SEER2) and YH6 (16 SEER2) meet CEE Tier 1 thresholds qualifying for IRA Section 25C credits. For maximum efficiency, the YZV Affinity Series (19 SEER2) uses an inverter compressor for load-matching. For furnace selection, match AFUE tier to energy cost sensitivity and climate.

What is the difference between the York YZV Affinity Series and the YH6 LX Series heat pump?
The YZV uses a variable-speed inverter compressor that continuously adjusts capacity, rated at 19 SEER2. The YH6 is a two-stage compressor rated at 16 SEER2, running at low or high capacity only. The YZV provides more precise temperature control at partial loads. The YH6 improves comfort over single-stage models at a lower upfront investment than the YZV.

What York heat pump qualifies for the IRA Section 25C federal tax credit?
York LX Series heat pumps (YH2F at 15.2 SEER2, YH6 at 16 SEER2) and the YZV Affinity Series meet ENERGY STAR and CEE Tier 1 requirements qualifying for IRA Section 25C tax credits. Eligibility depends on current IRS requirements.

Are York split system heat pumps compatible with non-York air handlers?
York split system heat pumps are designed to pair with York air handlers and furnaces for AHRI-rated matched system efficiency. Non-York air handlers can be used in some configurations, but AHRI-rated efficiency verification may not be available for the combination. Communicating York systems like the YZV require a compatible York communicating air handler or furnace.

How does SEER2 differ from SEER?
SEER2 is the 2023 DOE replacement for SEER, using a new M1 test methodology that results in ratings approximately 5 percent lower than equivalent SEER ratings. York equipment is rated in SEER2 under current DOE standards. The lower SEER2 number reflects the updated test standard, not a reduction in actual performance. York's current lineup runs from 14.3 SEER2 to 19 SEER2.
