SZ-4Z-303-2025
4 Zones
Looking for an efficient, year-round heating and cooling solution for your home? The Mitsubishi 4-Zone 42k BTU Ductless System with Hyper-Heat technology is designed to provide optimal comfort while reducing energy costs. Whether you are upgrading your home HVAC system, replacing inefficient baseboard heating, or need a reliable solution for hard-to-condition areas, this system offers an advanced combination of performance, flexibility, and energy efficiency.
At the heart of this system is the MXZ-SM42NAMHZ2-U1 outdoor heat pump, a powerful and energy-smart unit capable of delivering efficient heating even in sub-zero temperatures. Unlike conventional heating systems that struggle in extreme cold, Mitsubishi's Hyper-Heat technology ensures consistent and reliable warmth, making this system perfect for colder climates.
The indoor units are strategically designed to provide precise zoning and personalized comfort throughout your home. This setup includes two MLZ-KP09NA2-U1 ceiling cassette units and two wall-mounted units: the MSZ-GS09NA-U1 for smaller spaces and the MSZ-GS12NA-U1 for slightly larger areas. With four distinct zones, you can condition individual spaces according to your family’s preferences and usage habits. For instance, you can keep bedrooms cool at night without overconditioning the entire home, or maintain a comfortable office or living room without wasting energy on unused spaces.
The ceiling cassette units (MLZ-KP09NA2-U1) are a great choice for areas where wall space is limited, seamlessly integrating into your ceiling while distributing air evenly. These are ideal for living rooms or kitchens where a discreet and aesthetically pleasing solution is desired. Meanwhile, the wall-mounted units (MSZ-GS09NA-U1 & MSZ-GS12NA-U1) offer powerful and efficient climate control with advanced filtration, ensuring that your home's air remains clean and fresh.
One of the biggest advantages of this system is its zoning capability. Instead of conditioning your entire home at once like traditional HVAC systems, this setup allows for independent temperature control in each zone, eliminating hot and cold spots while significantly improving energy efficiency. This is particularly beneficial for multi-level homes, basement apartments, or home additions where maintaining consistent temperatures can be a challenge.
Additionally, Mitsubishi’s ductless systems are known for being whisper-quiet, making them ideal for bedrooms, offices, or media rooms where noise level matters. With advanced inverter technology, they adjust intelligently to demand, avoiding the energy waste associated with traditional on/off cycling HVAC systems.
If you're tired of high energy bills, inconsistent temperatures, and noisy HVAC operation, the Mitsubishi 4-Zone Ductless System offers an advanced, modern solution. Whether you're retrofitting an older home, renovating, or simply looking for superior comfort and efficiency, this system is designed to meet your needs while improving overall air quality and reducing energy consumption.
