Aciq Es-27z-m4c 4-zone Mini Split Heat Pump 27000 Btu 25 SEER2

Product Description

The ACIQ es-27z-m4c / aciq-09w-hh-md-4 is a 4-zone ductless mini split heat pump system rated at 27,000 BTU/h with a 25 SEER2 efficiency rating. It operates on 230 volts and uses R454B refrigerant, a lower-GWP alternative to R-410A that meets current EPA regulations. The system ships as a complete multi-zone package: one outdoor condenser paired with four 9,000 BTU/h wall mount indoor air handlers. Licensed HVAC technicians install this type of system in residential and light commercial applications where ductless zoned climate control is required year-round.

This system is suited for residential multi-room installs and light commercial spaces requiring independent heating and cooling in up to four separate zones. Typical applications include multi-bedroom homes, apartments, offices, and additions where running ductwork is not practical. Each zone is served by a dedicated 9,000 BTU/h wall mount head unit, allowing individual temperature control per space without affecting adjacent zones.

Key Features

• 27,000 BTU/h total system capacity across four zones
• 25 SEER2 efficiency rating for high-performance energy use
• R454B refrigerant — lower global warming potential, EPA-compliant refrigerant
• Four 9,000 BTU/h wall mount indoor air handlers included
• 230-volt operation suitable for standard residential electrical service
• Provides both heating and cooling for year-round operation

Compatibility

Designed as a matched 4-zone ductless mini split system; indoor air handlers and outdoor condenser are factory-matched. Consult ACIQ documentation to confirm compatibility with any third-party controls or accessories before installation.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle refrigerants under EPA Section 608 regulations. R454B is an A2L mildly flammable refrigerant — follow applicable safety codes and local regulations for handling and line set routing. Shut off all electrical power at the disconnect and breaker before making any wiring connections. Line set sizing, refrigerant charge, and electrical circuit sizing must comply with the manufacturer installation manual and local mechanical and electrical codes.
