FAQ– Reversing Valve for Heat Pump
Q1: What is a 4-way reversing valve in HVAC systems?
A: It’s a directional control valve that switches refrigerant flow between heating and cooling cycles in a heat pump. The 4-way design allows efficient flow reversal with minimal pressure loss.
Q2: What does a reversing valve do in a heat pump?
A: The reversing valve allows a heat pump to reverse the refrigerant direction, turning the system from cooling to heating mode or vice versa.
Q3: How much does heat pump reversing valve replacement cost?
A: Replacement cost varies by model and capacity, typically ranging from $100–$400 for standard residential units. KAK provides OEM and replacement valves for all major brands.
Q4: Do you offer solenoid coils with reversing valves?
A: Yes, KAK supplies reversing valves with integrated or separate solenoid coils and contactors for OEM heat pump applications.
Q5: Are KAK valves compatible with Goodman or Carrier systems?
A: Yes, our valves are compatible with most HVAC and heat pump brands, including Goodman, Carrier, LG, and Gree units.
