Aciq 27000 Btu 2-zone Mini Split Heat Pump 25 SEER2 230V R454B

Product Description

The ACIQ es-27z-m4c / aciq-06w-hh-md / aciq-18w-hh-md is a 2-zone wall mount mini split heat pump system rated at 27,000 BTU/h total capacity. Operating on 230 volts and charged with R454B refrigerant, the system achieves a 25 SEER2 efficiency rating. It delivers both heating and cooling across two independently controlled zones using one outdoor condensing unit paired with two indoor wall mount air handlers: one 6,000 BTU/h unit and one 18,000 BTU/h unit. Licensed HVAC technicians install and commission this type of system.

This system suits residential and light commercial applications where two separate spaces require independent temperature control. The wall mount indoor heads are a common fit for bedrooms, offices, studios, additions, and open living areas. The 25 SEER2 rating positions this system in the high-efficiency tier, making it appropriate for installations in states or jurisdictions with elevated minimum efficiency requirements. The R454B refrigerant charge complies with current low-GWP refrigerant transition standards.

Key Features

• 27,000 BTU/h combined system capacity across two zones
• 25 SEER2 efficiency rating for high-efficiency installations
• R454B refrigerant — low-GWP, A2L compliant refrigerant charge
• 230-volt single-phase operation
• Two wall mount indoor air handlers: 6,000 BTU/h and 18,000 BTU/h
• Provides both heating and cooling for year-round operation

Compatibility

Designed as a matched 2-zone mini split system; the outdoor unit es-27z-m4c is paired with indoor heads aciq-06w-hh-md and aciq-18w-hh-md. Do not mix these indoor units with non-matched outdoor units without verifying ACIQ system compatibility documentation.

Installation Notes

Installation must be performed by a licensed HVAC technician holding the appropriate EPA Section 608 certification for handling A2L refrigerants including R454B. Power down and lock out the electrical supply at the disconnect before any wiring or refrigerant work. Follow NEC requirements for minimum circuit ampacity, disconnect sizing, and wire gauge for 230-volt mini split installations. Indoor heads require proper wall mounting, condensate drainage routing, and leak-tested line set connections before system startup.
