3 Zones
Are you looking for a highly efficient, year-round heating and cooling solution for your home? The Mitsubishi 3-Zone 42k BTU Ductless System with Hyper-Heat is designed to provide exceptional comfort and energy savings, no matter the season. Powered by an advanced MXZ-SM42NAMHZ2-U1 outdoor heat pump, this system delivers high-performance climate control to three separate zones in your home, ensuring individualized comfort where you need it most.
What makes this system ideal for homeowners? If you have rooms that are difficult to heat or cool—perhaps a sunroom that gets too warm in summer or a basement that remains chilly in winter—this ductless solution is perfect for addressing uneven temperatures. The combination of indoor units, including the MLZ-KP09NA2-U1 (9K BTU ceiling cassette), MSZ-GS12NA-U1 (12K BTU wall-mounted unit), and MSZ-GS18NA-U1 (18K BTU wall-mounted unit), allows for precise zoning. That means you can customize temperatures in different areas of your home without the inefficiency of a traditional ducted system.
Beyond comfort, this Mitsubishi ductless system offers Hyper-Heat technology, ensuring reliable operation in extremely cold temperatures. Unlike conventional systems that struggle in freezing weather, Hyper-Heat maintains efficiency, keeping your home warm even when outdoor temperatures drop below zero. Plus, with whisper-quiet operation and advanced air filtration, you’ll enjoy cleaner, healthier air without the noise of older HVAC systems.
Whether you're upgrading from an outdated system, adding climate control to a home addition, or simply seeking a more energy-efficient solution, this Mitsubishi ductless system offers versatility, performance, and savings. Say goodbye to hot and cold spots—and hello to total home comfort.
