If you are servicing an older YORK or Johnson Controls geothermal / water-source heat pump, the name on the cabinet does not always tell the entire manufacturing story. Some YORK geothermal equipment sold under the Johnson Controls brand was manufactured by WaterFurnace's manufacturing operation and shares its underlying platform and components with WaterFurnace equipment.
That relationship matters when an older YORK or Johnson Controls geothermal part is difficult to identify or appears obsolete. Total HVAC Parts can research WaterFurnace replacement parts for applicable YORK / Johnson Controls private-label units when the model and serial number confirm the relationship.

YORK Geothermal Equipment Manufactured by WaterFurnace
Historical and current YORK geothermal documentation provides unusually clear evidence of this relationship. YORK geothermal literature identifies certain equipment as manufactured by WFI Industries in Fort Wayne, Indiana. WFI is the WaterFurnace manufacturing organization, and ENERGY STAR certification records for multiple YORK by Johnson Controls geothermal models list WaterFurnace International, Incorporated as the ENERGY STAR partner.
This is more than two manufacturers using similar compressors or controls. For applicable YORK geothermal product families, the YORK-branded unit was a private-label product built through WaterFurnace's manufacturing platform.
Why Many YORK and WaterFurnace Components Look the Same
Private-label equipment can carry different cabinet branding and model nomenclature while sharing major underlying components. Depending on the specific model and production period, that can include compressors, blower assemblies, motors, refrigeration components, heat exchangers, sensors, wiring components, controls and other service parts.
This is why a failed part from a YORK-branded geothermal unit may trace back to a WaterFurnace service part even when “WaterFurnace” does not appear on the equipment nameplate.
The Older Johnson Controls FX10 Connection
There is a second Johnson Controls connection that sometimes causes confusion. WaterFurnace itself used the Johnson Controls FX10 microprocessor controller on numerous older commercial water-source and geothermal heat-pump platforms. WaterFurnace service literature specifically identifies the Johnson Controls FX10 as a controller used for unit sequencing, protection, diagnostics and BAS communications.
Therefore, finding a Johnson Controls FX10 board inside an older WaterFurnace unit is normal. But the presence of an FX10 alone does not prove that a unit was private-labeled by Johnson Controls. The equipment model and serial number still need to be verified.
Can We Supply WaterFurnace Parts for a YORK or Johnson Controls Unit?
For units that can be confirmed as WaterFurnace-built private-label equipment, yes. We can research the original YORK / Johnson Controls model and identify the applicable WaterFurnace service part where the factory documentation supports the cross-reference.
We do not recommend ordering by visual similarity alone. Private-label model numbers, production revisions, control options and voltage configurations can change the correct replacement.
What to Send Us
If you have a YORK or Johnson Controls geothermal or water-source heat pump and need a replacement part, send:
- Complete equipment model number
- Complete serial number
- Photo of the equipment nameplate
- Existing part number, if readable
- Photos of the failed component and labels
- Voltage and other relevant component information
We can compare the unit against WaterFurnace-built product families and research the appropriate replacement instead of forcing you to hunt through two different branding systems.
Frequently Asked Questions
Did WaterFurnace manufacture YORK geothermal heat pumps?
Yes, certain YORK geothermal products were manufactured by WFI Industries, the WaterFurnace manufacturing organization in Fort Wayne, Indiana. ENERGY STAR records also identify WaterFurnace International as the partner behind multiple YORK by Johnson Controls geothermal models.
Are all YORK or Johnson Controls water-source heat pumps made by WaterFurnace?
No. The relationship is model-specific. YORK and Johnson Controls have sold other water-source equipment from other manufacturing platforms, so the exact model and serial number must be verified before using a WaterFurnace replacement part.
Why do older WaterFurnace units have Johnson Controls FX10 boards?
WaterFurnace used Johnson Controls FX10 controllers in a number of older commercial heat-pump applications. The FX10 handled unit control and supported BAS protocols such as N2, LonTalk and BACnet depending on configuration.
Can Total HVAC Parts find parts for a YORK private-label WaterFurnace unit?
Yes, when the equipment can be confirmed as a WaterFurnace-built YORK / Johnson Controls platform. Send the model, serial number and part information through our request a quote page, or browse our WaterFurnace replacement-parts collection.
