OLMO 4-Zone Custom Mini Split Heat Pump (-13°F), WiFi, E-Star: 21 SEER2/12.5 EER/9 HSPF (R410a)

I added the OLMO 4-Zone Mini Split to my sun-soaked city home, where the walls practically shimmer by noon. Installation was quick — one outdoor unit on the terrace, four slim indoor heads that blend right in. The real magic started when I turned it on: it tamed the afternoon heat without the usual blast of cold air, just a quiet, even calm. Now each room has its own rhythm — my bright living space stays crisp while the bedrooms keep their cozy hush. The system feels like it learns the light, adjusting itself as the day fades. For a city home that never stops glowing, this OLMO keeps the comfort perfectly balanced.

The delivery. It arrived like a metal monolith, dropped off by a guy who looked like he'd wrestled a bear. Surprisingly effective. It's like having tiny oasis in each room. No more arguing about the thermostat. My partner can live in arctic conditions while I enjoy a balmy tropical climate. And now, I'm sitting here, sipping iced tea, basking in the glory of my perfectly zoned climate control, and thinking.."

Upgrading our fourth-floor apartment in an older building with an Olmo multi-zone mini-split system was the best investment we've made, especially as summer temperatures here have grown noticeably hotter and more punishing over recent years. Operating as a single, ultra-efficient outdoor condenser wired to independent indoor units throughout our large two-bedroom layout, it effortlessly handles the massive, open-concept living, dining, and kitchen area without breaking a sweat, while allowing us to keep both bedrooms dialed into their own personalized comfort levels—all while eliminating the oppressive heat traps, humidity buildup, and frustrating noise that used to make living on the top floor unbearable.

shipping was fast, installed easy - qualified for rebates, got federal tax credits!

The Olmo 4-zone system is less like a standard AC and more like a silent climate-conductor for a chaotic house, effectively ending the "thermostat wars" by turning four disconnected rooms into independent thermal sanctuaries. While most multi-zone units feel like scaled-up window shakers, this 36k BTU beast operates with a sophisticated, low-frequency hum that stays whisper-quiet even when the Sierra-series inverter is fighting off sub-zero external temps. The real magic isn't just the 21 SEER2 efficiency—which effectively slashed my cooling overhead by nearly 40%—but the "Follow Me" remote sensing that shifts the temperature logic from the high-wall unit directly to my nightstand. It’s a high-spec, "set-it-and-forget-it" workhorse.

Our Olmo 4-Zone Mini Split just leveled up our home comfort. This thing is brilliant! I mean, four independent climate zones? Game. Changer. My bedroom stays cool, the kids' rooms are perfect, and the living area is just right – no more fighting over one thermostat. It's shockingly quiet and incredibly efficient. No messy ducts, just sleek units that blend in. This Olmo system isn't just about AC or heat; it's about pure, personalized comfort. Honestly, if you want total climate control that saves energy and simplifies life, this is it. Best home upgrade in ages!

The unit was turned on for the 1st time and boy it was so quiet I literally had to make sure the fan was spinning outside. the unit and air handlers cool very quickly. I also tested the heating it worked superb. I wont be using this until summer time gets here honestly. that's my main purpose for purchasing it. Living in the deep south requires good A/C. Customer service is also top notch. I would recommend anyone to give them a try. THEY ROCK!

I enjoyed installing my quad mini-split system as a home improvement project. super quiet, efficient, beautiful design, the romete control comes with batteries and a bunch of functions and modes. I am very happy with my purchase. I'll buy two more next year for another building. Thank you so much.

Product works well and was easy to install. Very efficient units. Most importantly the DIY installation saved me thousands on HVAC quotes. This unit heats and cools a 2,400 sq ft home and storage unit..

I took a bit of a gamble going with the Olmo 4-Zone Mini Split instead of one of the big-name brands—and I’m glad I did. This thing runs like it’s got something to prove. I’ve got units in four separate spaces, and each one seems to have its own personality: responsive, quiet, and consistent. I didn’t expect this level of precision from a system in this price range. The install wasn’t overly complicated, and once it was in, it blended right into the space. The Olmo doesn’t show off, and maybe that’s why it works so well. It’s not trying to be flashy—it’s just doing the job, quietly and effectively. No drama, no hot spots, no regrets.

Each of the four zones works really well. Whether it’s cooling or heating, I can tailor the comfort for each room without affecting the others, which is perfect for a multi-zone setup. The noise level is very low, making it unobtrusive while running. It’s been an overall positive experience, and I definitely recommend it to anyone looking for an energy-efficient and reliable mini-split system!

When my OLMO arrived, it didn’t come with a red carpet—but almost felt like it needed one. This powerhouse bundle included the outdoor hyper-heat unit, four discreet indoor units, remotes, and even Wi-Fi capabilities. Despite its heft, unpacking felt surprisingly doable—until I tried lifting the outdoor unit alone. Prices compared to brands like Mitsubishi or Daikin felt justifiable given the performance, and needing no central ductwork was a bonus. If you're after a multi-room comfort solution that’s quieter than your thoughts at 3 a.m., impressively efficient, and doesn’t need to pretend it’s fancy to perform—it’s your system.

I bought the Olmo 4 Zone Mini Split system because I wanted an efficient way to heat and cool multiple rooms in my home without having to rely on a central system. Each room gets to the right temperature quickly and quietly. The airflow is strong, but not overwhelming, and it maintains the temp pretty consistently. The inverter technology definitely helps with efficiency. the cost was more affordable than similar brands I looked at (like Mitsubishi or Daikin), and I didn’t have to compromise on performance.

I installed two of these units in a rental house, completely replacing the gas boiler. The systems work perfectly, were easy to install and came with all needed major components. The units have been in use for about 5 months now without a problem. They are quiet and the tenants report that they work well. I will definitely be ordering again in the future.
