Gree DUC18HP230V1R32AH Concealed Duct Mini Split Air Handler 18000 Btu/h 230V R32 Single Zone Indoor Unit

Product Description

The GREE DUC18HP230V1R32AH is an 18,000 BTU/h slim concealed duct indoor unit designed for single-zone and multi-zone mini split heat pump systems operating on R32 refrigerant at 208-230 volts. It installs inside a ceiling or wall cavity and distributes conditioned air through a short duct run, keeping all mechanical components hidden from the occupied space. DC inverter technology allows the unit to modulate capacity continuously, which reduces energy consumption compared to single-stage systems. Licensed HVAC technicians install this air handler as part of a matched All Match system, pairing it with a compatible GREE outdoor condensing unit. Rated SEER2 efficiency ranges from 22.0 to 24.0 depending on system configuration.

This indoor unit is suited for residential and light commercial applications where a wall-mounted or ceiling cassette solution is not preferred. The slim duct configuration is commonly installed in drop ceilings, soffits, or tight interstitial spaces where duct runs must remain minimal. It is part of the GREE All Match series, which supports both single-zone and multi-zone outdoor units, making it a flexible choice for new construction and retrofit projects. The unit weighs approximately 92.6 pounds and requires proper structural support at the installation location.

Key Features

• 18,000 BTU/h capacity for single-zone or multi-zone All Match system configurations
• R32 refrigerant — lower global warming potential than R410A
• High-efficiency DC inverter operation for variable-capacity output
• SEER2 rating range of 22.0 to 24.0 depending on matched outdoor unit
• Slim concealed duct design installs in ceiling cavities, soffits, or wall chases
• Rated for 208-230V / 1-phase / 60 Hz electrical supply

Compatibility

The DUC18HP230V1R32AH is confirmed as a component in GREE All Match multi-zone systems, including configurations paired with MUL30HP230V1R32AO and MUL42HP230V1R32AO outdoor units. It functions as a single-zone indoor unit or as one of multiple indoor units in a multi-zone setup. Verify outdoor unit compatibility using GREE All Match system pairing documentation before installation.

Installation Notes

Installation must be performed by an EPA Section 608 certified HVAC technician due to the use of R32 refrigerant, which is classified as mildly flammable (A2L). Shut off all power to the system at the disconnect before making electrical or refrigerant connections. The unit must be securely mounted to structural framing capable of supporting its weight, and all refrigerant line sets must be sized and leak-tested per manufacturer specifications and local mechanical codes. Follow ASHRAE and local jurisdiction requirements for ventilation and refrigerant charge limits in enclosed spaces when using A2L refrigerants.
