3 Zones
Are you looking for a highly efficient, whisper-quiet, and versatile heating and cooling solution for your home? The Mitsubishi 3-Zone 42k BTU Ductless System with Hyper Heat is designed to provide year-round comfort, even in extreme temperatures, while maximizing energy savings and improving indoor air quality. Whether you're upgrading your existing HVAC system, adding climate control to rooms that never reach the desired temperature, or building a new home with a modern and efficient heating and cooling solution, this ductless system is an ideal choice.
This system is powered by the advanced MXZ-SM42NAMHZ2-U1 outdoor condenser, which offers powerful multi-zone heating and cooling capabilities. Thanks to Mitsubishi's Hyper Heat technology, this system ensures reliable heating even in sub-zero temperatures, making it a great option for homeowners in colder climates who need consistent warmth during harsh winter months.
With the flexibility of three indoor zone units, you can customize your home’s comfort to suit your specific needs:
- MLZ-KP12NA2-U1 (12,000 BTU) – A sleek, recessed ceiling cassette ideal for spaces where wall space is limited, such as kitchens or living rooms.
- MSZ-GS12NA-U1 (12,000 BTU) – A wall-mounted unit great for bedrooms, offices, or guest rooms, providing quiet operation and personalized comfort.
- MSZ-GS18NA-U1 (18,000 BTU) – A larger wall-mounted unit perfect for bigger spaces like open-concept living areas or master bedrooms.
This system is particularly beneficial for homes with multiple zones that require independent temperature control. For example, if your master bedroom is always too warm while your upstairs office tends to be chilly, each indoor unit allows personalized temperature adjustments, eliminating hot and cold spots throughout your home.
Additionally, Mitsubishi's advanced inverter-driven compressor adjusts power based on real-time demand, ensuring incredible energy efficiency, lower utility bills, and reduced carbon footprint. Since this system does not rely on bulky ductwork, it prevents common duct-related energy losses, making it a smart choice for both old and new homes. Plus, the included filtration system improves indoor air quality by trapping allergens, dust, and pollutants.
No matter the season, the Mitsubishi 3-Zone Ductless System is built to deliver the perfect temperature in every corner of your home – all while operating quietly and efficiently. Whether you want added warmth during winter, a cool retreat in the summer, or simply better control over your indoor climate, this system offers a seamless and cost-effective solution.
