ClimateMaster Reversing Valve for Geothermal Heat Pumps

The ClimateMaster reversing valve (also called a heat pump reversing valve or 4-way reversing valve) is a replacement component for ClimateMaster geothermal and water-source heat pump systems. It switches the system between heating and cooling by redirecting refrigerant flow.

Key Features:

• Heating/cooling changeover: The valve redirects refrigerant flow so the system can run in either mode.
• Pilot-operated, solenoid-actuated design: Valves in this line are 4-way and work with a low-voltage reversing valve coil on the heat pump control circuit.
• Built for geothermal and water-source systems: It is intended for residential and commercial ClimateMaster equipment that uses a ground loop or water loop.
• OEM-style replacement: Choosing the correct valve helps restore factory reversing function and keeps the system running efficiently.

Symptoms of a failing valve: A heat pump that stays in one mode no matter what the thermostat calls for may have a failed or sticking reversing valve. Replacement involves refrigerant recovery and recharge, so a qualified HVAC technician should install it.
