4 Zones
Are you looking for an efficient, year-round comfort solution for your home? The Mitsubishi 4-Zone 42,000 BTU Ductless System with Hyper-Heat is designed to deliver exceptional heating and cooling while maximizing energy efficiency and personalized comfort. Whether you're dealing with hot summers or freezing winters, this system, powered by the MXZ-SM42NAMHZ2-U1 outdoor heat pump, ensures consistent indoor temperatures even in extreme conditions. With a combination of indoor units—one MLZ-KP12NA2-U1 (a 12,000 BTU ceiling cassette) and three MSZ-GS09NA-U1 (9,000 BTU wall-mounted units)—this setup is perfect for a variety of home layouts.
Does your home have rooms that never seem to reach the right temperature? This system is ideal for homeowners seeking zone-specific comfort. Imagine the ability to maintain different temperatures in separate areas of your home—perhaps a cozy bedroom at night while keeping the living room cooler during the day. With four independently controlled zones, you have the flexibility to customize your home’s climate, boosting comfort and reducing energy waste.
One of the standout features of this Mitsubishi ductless system is Hyper-Heat technology, specially designed to provide reliable warmth even in freezing temperatures. If you live in a cold climate where traditional heat pumps struggle in winter, this system can heat your home efficiently even when outdoor temperatures plummet. Plus, Mitsubishi’s advanced inverter technology continuously adjusts to maintain the perfect balance between performance and efficiency, preventing energy waste and helping to lower utility bills.
This ductless system is also an excellent solution for older homes, additions, converted garages, or any space without existing ductwork. Unlike traditional HVAC systems that may require expensive duct installation, Mitsubishi’s ductless system is a cost-effective and minimally invasive solution. Not only will you enjoy whisper-quiet operation, but you’ll also enhance indoor air quality thanks to advanced filtration features that help remove allergens and pollutants from your home.
If you're searching for a smart, energy-efficient way to heat and cool multiple areas of your home, the Mitsubishi 4-Zone Hyper-Heat system offers the perfect balance of comfort, efficiency, and reliability.
