Who makes York now?
York has a long history in American heating and cooling, and for years its residential furnaces and air conditioners came from Johnson Controls. That changed on July 31, 2025, when Johnson Controls completed the sale of its residential and light-commercial HVAC business to Robert Bosch GmbH. Bosch now runs York residential equipment inside its Bosch Home Comfort Group, alongside its own Bosch heat pumps. Johnson Controls kept the YORK trademark and its large commercial business, so Bosch uses the name under license.
For a homeowner with a York furnace in the basement, the sale changes very little. The equipment is the same, the model and serial numbers are the same, and the parts are looked up the same way. We check the rating plate, pull the correct part number, and repair it.
Affinity, LX and York's entry models
York sorts its residential equipment into tiers. Affinity is the top: the YP9C modulating furnace (York's literature rates it up to 98% AFUE), the YZV variable-capacity heat pump and communicating controls. LX is the middle, built around two-stage furnaces like the TM9V and two-stage outdoor units. Below that are York's basic single-stage furnaces and condensers, the kind of equipment often chosen for rentals and tight budgets.
In a Minnesota house, the tier mostly changes how the furnace runs through a long cold night. A single-stage York runs at full fire every cycle. A two-stage LX mostly idles along on its low stage, running longer, gentler cycles that keep upstairs and downstairs closer in temperature. A modulating Affinity adjusts in smaller steps still.
What goes wrong with York furnaces in a Minnesota winter?
The winter list on York condensing furnaces is familiar: a pressure switch that won't close because of a frosted side-wall vent or a backed-up condensate trap, an inducer motor that's worn out, a cracked igniter, or a flame sensor coated with residue. That last one often shows up as a furnace that lights, runs a few seconds and shuts off. If yours is turning on and off constantly, our guide to furnace short cycling walks through the causes.
On any older furnace, York included, we inspect the heat exchanger during a no-heat call or tune-up. A cracked heat exchanger can leak carbon monoxide, and Minnesota law requires working CO alarms within 10 feet of every sleeping room. Our post on cracked heat exchanger symptoms explains what we look for.
On Affinity systems, the thermostat, furnace and outdoor unit communicate, and the control keeps a fault log. We read it before replacing a board. In summer, York condensers need the usual parts: capacitors, contactors and fan motors, plus a leak search on any system low on refrigerant.
York heat pumps in the cold
York's top heat pump, the Affinity YZV, is a variable-capacity communicating unit that York rates at 19 SEER2. Like every air-source heat pump, it produces less heat as the outdoor temperature drops, and it runs defrost cycles on humid, near-freezing days. That defrost steam off the outdoor unit is normal, and our post on heat pump defrost mode explains it. Here, a York heat pump nearly always works as the electric half of a dual-fuel system, with a gas furnace behind it for the coldest weeks. Before recommending one, we work out how much of your winter the heat pump can realistically carry.
Is York a good choice for a replacement system?
York is a reasonable mid-priced choice, and the LX tier covers what most Minnesota homes need. The size comes from a Manual J load calculation of your home, and our furnace installation page walks through the install itself. York's terms have called for online registration within 90 days to get the 10-year parts coverage, so register within that window.
Dig out the install date and any registration paperwork if you have them, then call 612-429-3465 (7am–9pm, seven days) or fill in the request form. If the furnace is down, we treat it as a priority call. You'll have a written, flat-rate price in hand before we start.

York questions
Who owns York now?
Bosch. On July 31, 2025, Johnson Controls completed the sale of its residential and light-commercial HVAC business to Robert Bosch GmbH. Bosch runs it inside its Bosch Home Comfort Group and uses the YORK name under license, since Johnson Controls keeps the trademark and its large commercial York business. Your York furnace is the same equipment either way.
Is my York warranty still good after the sale?
The warranty on your unit is tied to its registration and terms at the time of install, so keep your paperwork. York's terms have required online registration within 90 days of installation for the 10-year parts limited warranty; unregistered units fall back to a shorter term. If you're unsure of your status, the serial number is what you'll need to check it.
What's the difference between York Affinity and LX?
Affinity is York's premium tier: modulating furnaces, variable-capacity heat pumps and communicating controls. LX is the mid tier, mainly two-stage equipment. For most Minnesota homes on natural gas, a two-stage LX furnace covers the heating season well. Affinity makes more sense in larger homes or when you want a variable-speed heat pump.
Why does my York furnace lock out on the coldest nights?
On a York condensing furnace the usual cause is the vent and drain: a frosted side-wall vent, a backed-up condensate trap, or a pressure switch that won't close because of either. We clear the vent and trap, then find out why they iced up so the lockout doesn't come back.
