Wait! This is an Individual Component To build a working system, this unit must match your other equipment in two ways:

  • Same Brand Only: Only pair with other same Brand and Series.
  • Same Refrigerant: Both units must use the exact same gas type (R454B, R32, or R410A).

Mixing different brands or refrigerant types will cause the system to fail and void your warranty.
