Description
The Carrier EA36UZ022 is an OEM thermostatic expansion valve (TXV) engineered as a direct replacement for compatible Carrier refrigeration and air conditioning systems. Thermostatic expansion valves are critical refrigeration cycle components responsible for precisely metering refrigerant flow into the evaporator coil, maintaining the correct superheat level for maximum system efficiency and compressor protection.
Why the TXV Matters
A properly functioning TXV ensures your system operates at peak efficiency by continuously modulating refrigerant flow in response to changing load conditions. A worn or failed TXV can result in poor cooling performance, compressor flooding, excessive superheat, or elevated energy consumption. Replacing it with a genuine Carrier part restores factory-specified performance and protects the longevity of the entire refrigerant circuit.

Installation Notes
Installation of a TXV should be performed by a qualified HVAC/R technician. Always recover refrigerant per EPA regulations before replacing the valve, and verify proper superheat settings after installation using calibrated gauges and thermometers.
