SZ-4Z-283-2025
4 Zones
Are you looking for a powerful, highly efficient, and customizable heating and cooling solution for your home? The Mitsubishi 4-Zone 42,000 BTU Ductless System with Hyper Heat is designed to offer year-round comfort, energy savings, and flexible zoning to meet your home's specific needs. This system includes the MXZ-SM42NAMHZ2-U1 outdoor heat pump and a well-balanced combination of indoor units: a MLZ-KP18NA2-U1 for larger spaces, a MLZ-KY06NA-U1 for smaller rooms, and two MSZ-GS09NA-U1 units, providing tailored comfort for different areas of your home.
What makes this system stand out is its Hyper-Heating Inverter® (H2i®) technology, allowing it to deliver efficient heat even in extreme cold conditions—as low as -13°F—making it an ideal choice for homeowners in colder climates. Whether you have a multi-story home, an open-concept living space, or rooms that heat and cool unevenly, this system ensures consistent comfort without the energy waste of traditional HVAC solutions.
The ductless design eliminates the need for extensive ductwork, making it perfect for older homes, additions, finished basements, or attics where extending a ducted system is impractical. Each indoor unit operates independently, allowing you to set different temperatures in different rooms—so you can keep the living room cozy while maintaining a cooler temperature in the bedrooms for a better night’s sleep.
Beyond comfort, Mitsubishi Electric’s advanced inverter-driven technology ensures energy efficiency and lower monthly utility costs by only using the necessary energy to maintain your preferred temperature. In addition, these indoor units operate ultra-quietly, so you can enjoy a peaceful home environment without the disruptive noise of traditional HVAC systems.
Whether you're upgrading your existing HVAC system, adding supplemental heating and cooling, or looking for a cost-effective way to zone your home, the Mitsubishi 4-Zone Ductless System provides the performance, efficiency, and flexibility you need. With sleek and discreet ceiling-mounted and wall-mounted options, it seamlessly integrates into any home design while delivering superior year-round comfort.
