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.

Iโll be honest โ I was skeptical about switching to a mini split system. Five zones sounded like overkill, and I wasnโt sure I could pull off the install. But the Norton system proved me wrong on both counts. Setup was way less stressful than I expected (thanks to the pre-charged lines), and now each room feels like its own little comfort zone. My office stays cool while the bedrooms stay cozy โ no thermostat fights anymore. I barely hear it running. Itโs one of those upgrades that quietly makes your whole home feel better.
5 Zone Split AC
Brian D. Rucker · July 2026
Living in a drafty old draft-trap of a house used to mean freezing through winter and sweating through summer, but plugging into this Norton 5-zone mini split felt like giving our ancient walls a cozy, high-tech blanket that finally stands up to the weather.
I finally pulled the trigger on the Norton 5-Zone from Mini Split Warehouse
Jay Higgins · January 2026
With five zones, the copper lines look like a spiderweb during setup. Do yourself a favor and hire a pro to vacuum the linesโitโs worth the peace of mind. Itโs sleek, efficient, and the "Gold Fin" coating feels like it'll actually last. If youโre tired of hot spots in your house, this is the fix.
I'm happy with the purchase. It has made my home very comfortable.
Merrill Tetreault · April 2025
We have a larger home with some weird temperature differences between rooms, and this system handles it like a champ. Iโve been using the Norton 5-Zone Mini Split for a few months now. Five zones means five remotes, but the individual control is fantastic.
Ordering was easy, and delivery was prompt.
Customer service was helpful when I had questions.

All at Once
Theodore A. · April 2025
I had five areas I really wanted to control separately. Each zone got its own sleek, wall-mounted unit, and I love how clean they look โ no bulky equipment or weird vents messing with my decor. The SEER2 rating is no joke.
New Home
Dennis M · July 2025
When we moved into our newly built home, I wanted a heating and cooling system that wouldnโt just be efficient but also flexible enough to handle different areas of the house without wasting energy. After a lot of research, I decided on the Norton 5-Zone Mini Split Heat Pump AC, and it's turned out to be a perfect fit for our needs.
Since it was new construction, we had the freedom to plan ahead, and Iโm so glad we opted for a ductless setup. We installed the five indoor units strategicallyโtwo upstairs for the bedrooms, two downstairs (living room and kitchen), and one in the guest room. Each zone has its own remote, and the ability to control them separately is a game changer. No more arguments over the thermostatโeveryone can set their room how they like it. For a new home, this mini split system checked all the boxes: easy to install, modern-looking, quiet, powerful, and energy-conscious.
Keeping Cool in the Shop and the Office
William Poland · September 2025
We installed the Norton 5-Zone system in one of our tire shops first, mainly because our old rooftop unit was on its last legs and the waiting area always felt like an oven. What really sold me was the ability to split zones between the office, customer lobby, stockroom, and even parts of the shop floor where guys spend most of their day. After seeing how well it worked, we decided to roll it out in two more of our stores. Each location has slightly different layouts, but the flexibility of this 5-zone setup meant we could tailor itโmore focus on customer comfort up front in one shop, more coverage in the service bays at another.

What Nobody Tells You Before You Buyโพ
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.
