HIGH-FREQUENCY INVERTER TECHNOLOGY: Enables the compressor to reach maximum speed within 6 seconds on start up HIGH-EFFICIENCY PIPES
Norton Multi Zone systems, with inverter technology, are some of today’s most advanced ductless split heat pumps. Up to 5 indoor units can be connected to a single outdoor unit, reducing the number of outdoor units required. All indoor units can be individually controlled and do not need to be installed at the same time.
With Norton heat pump technology, offers dependable cooling as well as the capability to heat in ambient temperatures as low as -13°F, making it an excellent, energy-efficient solution for colder climates.
Wall Mount • Modes: Cool, Heat, Dry, Fan, Auto • Turbo Mode • Four fan speeds • Sleep Mode • ECO Mode • Up-Down Louver control (fixed or swing) • Follow Me (senses temperature at handheld remote) • Quiet indoor operation • Aluminum Golden Hydrophilic pre-coated fins •(5yr Warranty) - Cut Sheets Below
Slim Ducted (Hidden/Concealed): Slim Ducts provide an inconspicuous solution, hidden in attics and ceiling crawl spaces, without the energy loss associated with central ducted systems. Slim Ducts offer flexibility of installation as the ducts can be directed into separate areas which are collectively controlled by one wall thermostat. For example, one slim duct can be directed to cool and heat hallways, closets, laundry rooms, and bathrooms of a home while the bedrooms themselves are controlled independently. Slim Ducts are available in 9K, 12K, 18K and 24K Btu/h models. Condensate pump built in. (5yr Warranty). Cut Sheets below
Extra Low Temperature Heating For when its cold outside, the heat output for this system is rated capacity down to -13° F, making this a primary heat source and eliminating the need for a backup heat source.
Stepless Frequency Adjustment Precise control of the system maintains stable and constant room temperature while reducing sound level and saving energy.
Norton Mini Split AC is your go-to solution for year-round comfort! This heat pump delivers powerful heating and cooling performance, even in temperatures as low as -13 F. With a remarkable SEER2, EER, and HSPF ratings, you can enjoy energy efficiency without sacrificing comfort. The package includes a sleek indoor unit with a remote, and an outdoor unit designed for durability and efficiency. Enjoy features like independent dehumidification, a 24-hour timer, and multiple modes including Turbo, Auto, Sleep, and Eco. The follow-me function ensures the perfect temperature wherever you are, while the easy-clean filter keeps the air fresh and healthy.
The Norton Multi-Zone system proved to be the ideal solution for this fourth-floor clinical build-out, offering a seamless installation that effectively bypassed the logistical headaches of traditional bulky HVAC hardware. By powering five independent indoor units from a single high-efficiency outdoor condenser, we were able to provide each rental cubicle with its own dedicated climate profile, allowing practitioners to customize their environment without impacting neighboring zones. The whisper-quiet operation is particularly impressive in this setting, as the ultra-low decibel output maintains the necessary acoustic privacy and calm atmosphere required for patient consultations. Furthermore, the inverter technology ensures that the system scales its energy consumption to meet the exact demand of occupied cubicles, delivering a high-performance, cost-effective cooling solution that meets the rigorous standards of a modern professional medical facility.
Total Comfort, Room by Room
John Hafer · June 2025
I’ve had the Norton multi-zone mini split for a few months now, and honestly, it’s been a game changer. I can set different temps in different rooms, which keeps everyone happy—and it runs whisper-quiet, even outside. It cools fast in the summer . The “follow-me” remote is a surprisingly useful feature, and I like that it auto-restarts if the power blinks out.You’ll definitely want a pro to install it, and it’s not the cheapest option out there. But for the comfort and energy savings, it’s been totally worth it.
I’d definitely recommend this system.

After a ton of research and comparing different brands and systems, I finally decided to go with the Norton Multi Zone Mini Split Heat Pump AC, and honestly, I’m really happy with my decision. I got the 2-zone setup for my home—one unit for the living room and one for the master bedroom—and it's made a noticeable difference in both comfort and energy efficiency. Each unit comes with its own remote, and I haven’t had any trouble programming or using them. I do wish it had a smart/WiFi feature built-in, but I’ve heard you can buy a separate module to enable that if needed. It’s affordable, reliable, and performs just as well—if not better—than some of the more expensive name brands.
Finally Beat the Humidity
David Maupin · October 2025
I installed the Norton Multi-Zone Mini Split in my home, where humidity used to cling to everything—walls, floors, even my mood. From day one, it changed the air completely. The “Dry” mode quietly pulls the moisture out without freezing the place, and each zone keeps its own balance.
Installation took care—especially with drain lines and insulation—but once it was sealed up right, the difference was instant. No more sticky mornings or foggy windows, just calm, crisp air that actually feels clean. If your house sweats like mine did, this system doesn’t just cool—it rescues the atmosphere.
It’s like the HVAC system grew a brain.
Agustin C. · May 2025
Installation wasn’t exactly plug-and-play, but that’s kind of the nature of multi-zone systems. I hired a pro and had it running the same day. The indoor units don’t look like bulky wall wart boxes either — they’re low-profile, clean, and surprisingly modern. One’s in my office and it doesn’t mess with my Zoom background, which says a lot. You know how some systems kick on with a roar, or blow cold air right at your face? Not this one. The fans ramp up gently. The compressor outside is so quiet, I actually checked it twice the first week to make sure it was running. Spoiler: it was — the house just felt right. I stopped thinking about heating and cooling, and that’s probably the best review I can give. No more loud cycling. No more “why is it freezing in here?” mornings. Just comfortable, controllable, whisper-quiet air exactly where you want it.
Comfort in every corner
Douglas Smith · August 2025
Living in a large, well-insulated house has its perks—steady indoor temperatures, lower drafts—but it also means finding a system that can heat and cool each space evenly without wasting energy. The Norton Multi-Zone Mini-Split Heat Pump AC ended up being the perfect match. With multiple indoor units connected to one outdoor system, I can fine-tune each area without blasting the whole house unnecessarily.
In the winter, the heating performance is impressive. Even when the temperature outside dipped to the negatives, every room stayed warm and cozy without overworking the system. For a home our size, it’s rare to find a system that delivers comfort, efficiency, and control this well.

What Nobody Tells You Before You Buy▾
If you are looking for mini splits, most sellers cover the basics: an outdoor compressor connected to indoor units via small refrigerant lines, high energy efficiency without duct loss, and separate room temperatures — plus the simple setup needing just a small 3-inch wall opening. All true, but there are critical technical details and long-term ownership realities almost nobody tells you before you buy.
Beyond washing your mesh air filters every few weeks, mini splits need a deep chemical cleaning of the internal blower wheel and evaporator coil every 1–2 years. Because the heads recirculate the air in your living space, neglected moisture can breed toxic black mold inside the barrel fan. And while most guides cover summer condensation draining from the indoor head, heat pumps reverse in winter: during freezing weather the outdoor unit sheds gallons of water in defrost cycles — without a base pan heater or proper drainage that runoff freezes solid, destroying fan blades and icing the compressor base.
Finally, budget for electrical and warranty requirements upfront. A multi-zone system frequently requires upgrading your home's main electrical panel — often from 100-amp to 200-amp service — plus dedicated 208/230V double-pole breakers. Most importantly, beware of online DIY claims: almost every major manufacturer explicitly voids your multi-year parts and compressor warranty unless a licensed HVAC technician performs the final nitrogen pressure test, line evacuation, and refrigerant commissioning.
