Introducing the Mitsubishi 36,000 BTU Multi-Zone Outdoor Unit MXZ-SM36NL , an advanced multi-zone heat pump engineered for precise, efficient, and quiet heating and cooling in up to four zones. Built on Mitsubishi’s trusted INVERTER technology, the MXZ-SM36NL delivers dependable comfort year-round with exceptional installation flexibility. This model requires a compatible Mitsubishi branch box when paired with M- or P-Series indoor units.
The MXZ-SM36NL offers a maximum cooling capacity of 36,000 BTU/h and a maximum heating capacity of 41,000 BTU/h at 47°F , ensuring reliable performance in a range of climates. Even in colder conditions, it maintains impressive output—delivering 36,000 BTU/h at 17°F and 29,000 BTU/h at 5°F, with continued operation down to -13°F. Efficiency ratings reach SEER2 up to 23 , HSPF2 up to 11 , and COP values up to 4.0 at 47°F , earning ENERGY STAR® certification for most configurations.
Designed with durability in mind, the MXZ-SM36NL features a Blue Fin anti-corrosion coating on the heat exchanger and base panel, tested for 2,000 hours to ASTM B117 standards. A twin rotary INVERTER-driven compressor (model MRB36FEGMC-L) adjusts output precisely to meet demand while maintaining quiet operation—just 49 dB(A) in cooling and 53 dB(A) in heating . The Munsell 3Y 7.8/1.1 finish offers a clean, modern look, and the optional base pan heater enhances cold-weather performance.
Installation flexibility is unmatched, supporting piping runs up to 492 ft total with a branch box (787 ft without) and a maximum height difference of 164 ft between outdoor and indoor units. The system supports up to four indoor units with a branch box and offers a maximum connected capacity of 46,800 BTU/h. Refrigerant is factory pre-charged with 2 lbs. 11 oz. of R454B , minimizing installation time.
Safety and protection features include compressor overcurrent detection, compressor thermal protection, fan motor overheating/voltage protection, and high-pressure safety controls. With a compact footprint of 41-11/32" W x 13" D x 52-11/16" H and a weight of 250 lbs , the MXZ-SM36NL is built for robust performance without dominating outdoor space.
Whether cooling in the heat of summer or heating through frigid winters, the Mitsubishi MXZ-SM36NL stands out as a quiet, energy-efficient, and reliable multi-zone outdoor unit—ideal for homeowners seeking powerful climate control with the flexibility to support multiple indoor units.
