Mitsubishi Electric 36,000 BTU 17.6 SEER2 Tri Zone Wall Mounted Ductless Mini Split Heat Pump System 6+9+15 R454B Refrigerant | MXZ-5D36NL-MSZ-GX06NL-MSZ-GX09NL-MSZ-GX18NL

Product Summary

This bundled Mitsubishi Electric Trane multi-zone heat pump system is built around the MXZ-5D36NL outdoor unit with matched wall-mounted MSZ-GX indoor units. The outdoor unit delivers 35,400 BTU/h rated cooling and 36,000 BTU/h rated heating for zoned comfort across multiple rooms. It supports 2 to 5 connected indoor units with up to 41,000 BTU/h of connected capacity for flexible layout planning. The system uses R454B refrigerant and is designed for 208/230V, 1-phase, 60 Hz electrical service. Included indoor equipment: 1× MSZ-GX06NL wall-mounted indoor unit, 6000 BTU cooling, 7200 BTU heating (up to 448 CFM airflow); 1× MSZ-GX09NL wall-mounted indoor unit, 9000 BTU cooling, 10900 BTU heating (up to 448 CFM airflow; sound as low as 19 dB(A)); 1× MSZ-GX18NL wall-mounted indoor unit, 18000 BTU cooling, 21600 BTU heating (up to 650 CFM airflow; sound as low as 28 dB(A)).

On efficiency, the MXZ-5D36NL is rated up to 19.2 SEER2 and 9.3 HSPF2 (IV) in non-ducted configurations to help manage operating cost. A variable speed INVERTER-driven twin rotary compressor stages capacity to match demand and reduce cycling. Blue Fin heat exchanger coating is specified for coil protection in outdoor environments. Outdoor airflow is listed at 2,306 CFM in cooling and heating to support heat exchange across zones. The system is ENERGY STAR® certified in the non-ducted configuration.

Control flexibility comes from multiple supported control paths, including a back-lit handheld remote with the indoor units. GX-series indoor units list multiple control options including Comfort app connectivity and third-party interfaces, with wired and wireless controller options. The outdoor unit provides S1-S2 AC and S2-S3 DC communication voltages for system coordination. With independent indoor heads, each zone can be scheduled and adjusted for temperature and fan speed based on occupancy. This zoning approach can reduce wasted conditioning in unused rooms while maintaining comfort where needed.

Comfort performance is driven by multi-speed indoor fan operation and the system’s ability to modulate output. Sound pressure level for the MXZ-5D36NL is listed at 58 dB(A) in both cooling and heating for outdoor operation. Depending on the selected MSZ-GX indoor models, indoor sound can range down to 19 dB(A) on the smallest GX heads or higher on larger capacities. Indoor airflow ranges by model and fan speed, with published maximum cooling airflow reaching up to 765 CFM on larger GX indoor units. Features such as Econo Cool, Powerful Mode, and Smart Dry Mode are listed on GX indoor units to refine comfort and humidity control.

This bundle fits residential and light commercial spaces that need multiple independently controlled zones from one outdoor unit. Wall-mounted indoor units suit bedrooms, living areas, offices, and additions where ductwork is impractical. The outdoor unit operating range lists cooling intake air temperatures up to 115°F and down to 14°F for comfort-cooling applications. Heating thermal lock-out and re-start temperatures are listed, supporting cold-weather operation strategies when properly applied.For buyers in New York and the Northeast, zoning can help target heat where it’s needed most during shoulder seasons and winter operation.

System serviceability and durability are supported by protections such as compressor thermal protection and overcurrent detection. The outdoor unit uses reverse-cycle defrost and lists optional base pan heater availability for cold-weather moisture management. Maximum total piping length is listed at 230 ft, with up to 82 ft to the farthest indoor unit and up to 49 ft of height difference. These piping allowances help accommodate multi-story layouts and more complex indoor head locations. For contractors and wholesalers, the multi-zone platform can standardize around one condenser while mixing GX indoor sizes to match loads.

In summary, the MXZ-5D36NL bundle provides a single outdoor heat pump with multiple wall-mounted indoor zones for targeted comfort. It combines R454B refrigerant, inverter modulation, and published efficiency up to 19.2 SEER2 and 9.3 HSPF2 (IV) in non-ducted applications. Indoor unit sizing choices from the MSZ-GX lineup let the system cover small rooms through larger open areas with appropriate airflow. The 2–5 zone connection capability supports future flexibility when expanding or remodeling conditioned spaces. This makes the bundle a practical option for direct-to-consumer projects and for wholesale procurement requiring consistent Mitsubishi multi-zone performance.
