Customer Reviews
(write review)Excellent zone control
"I m very happy with my OLMO multi-zone ductless system. It delivers the flexible zoned comfort I was after, operates quietly and efficiently, and feels modern. If I were to sum it up: I feel I got great value for what I needed (multi-zone, heating cooling, modern controls)." Hiram Garcia - Thursday, October 23, 2025
OLMO Custom Multi-Zone Mini-Split
"I went with the OLMO Mini Split because I liked the flexibility of choosing exactly how many rooms I wanted to cover. Installation was smooth, and within a day I had quiet, efficient cooling in multiple areas. What impressed me most is how well it heats on colder nights without struggling. The Wi-Fi control is a nice touch too super convenient when I forget to adjust before heading out. For the price, it feels like a smart, reliable upgrade." Adrian L - Wednesday, August 20, 2025
From Chaos to Comfort
"When I first moved into this quirky, oddly-shaped home, I thought the multiple small rooms would give it charm. Instead, it gave me a headache every summer. Each room had its own temperature tantrum. I finally gave up trying to wrangle a solution with fans, window units, and sweating through the night until I installed the Olmo Custom Multi 1-4 Zone Ductless Mini Split Heat Pump. The flexibility of this system was a game-changer. I chose a mix of wall units and a ceiling cassette for different zones, and I ve never felt this level of control before. The outdoor unit runs so quietly that I thought it wasn t working at first. What really surprised me, though, was the heat pump performance this past winter it handled chilly mornings like a champ. I genuinely feel like I ve upgraded not just my HVAC system, but my entire daily comfort. This thing didn t just cool the house it restored my peace." Myrtle Atkinson - Thursday, July 10, 2025
One of the biggest pleasant surprises
"From the moment I started looking into multi-zone systems, the Olmo really caught my eye. The idea of being able to precisely control the temperature in different areas of my home or business was a game-changer. When the system arrived, the packaging was secure, and all the components were accounted for, which was a relief. Now, I can crank up the AC in my office without making the bedrooms frigid. It's made a monumental difference in my comfort throughout the day, and it's something I genuinely appreciate every single day." Dean Reymond - Saturday, May 31, 2025
Olmo multi-zone
"Ordered this Olmo multi-zone for our place, lured by the promise of tailored cooling. Four zones felt ambitious, and the install by Mateo was... an event. This Olmo system is smart, offering a level of customized comfort our old setup couldn't dream of. But it's not effortless. It demands attention, a bit of patience, and maybe a willingness to occasionally call Mateo back for a tweak. Worth it for the tailored comfort? Mostly, yes. Just know it's a more involved relationship than a simple on/off switch." Jack D. McPhee - Friday, May 9, 2025
Olmo Custom Multi-Zone system
"The shipping took a little longer than I'd hoped, but considering it was a custom configuration, it was understandable. Everything arrived securely packaged, though, and all the components were accounted for, which was a relief. Now for the best part the actual performance! The individual zone control is fantastic. My home office tends to get really warm in the afternoons, while the bedrooms stay relatively cool. Now, I can crank up the AC in my office without making the bedrooms frigid. It's made a huge difference in my comfort level throughout the day." M. Batz - Saturday, April 26, 2025
Happy Wife Happy Life!
"Installed the system in June of 2023. I bought this system for the bedroom and living room due to my wife having hot flashes (Happy Wife Happy LIFE). The electric bill savings paid for this system within 9 months. System must be maintained, clean filter monthly, do not skip, clean evaporator coils every 6 months for best performance. Just a personal recommendation. 1.5 years of savings and no issues." Jess A. Barry - Wednesday, January 29, 2025
Quality product at competitive pricing and quick shipping
"There are lots of options when it comes to mini-splits. But after spending time talking with experts, it became clear that this was the system we needed. The system came with multiple heads and you can select options like ceiling mount or wall mount. It has the ability to heat in extremely cold weather. The kicker was - the price was great! We will buy Olmo again for our next cabin!" A. Walker - Friday, October 25, 2024
Nice system, would buy again.
"We have never had air before as we have a boiler. Very easy install...with the help of a friend! The units are very efficient. I really like that you can have multiple isolated areas on the same unit." George A - Friday, October 25, 2024
I refer all my customers to use your product

Amazing Product & Customer Service!
"Used in a mini warehouse/office - it is everything that was promised, and more ! Impeccable service and quick shipping" John Martin - Wednesday, October 16, 2024
10 months after install
"This split system keeps up with the hat outside temps here in Kentucky. It is a lot cheaper to run than and Air conditioner. I would have gotten one sooner if i knew how it reduced my electric bill. I recommend professional installation though. The units are heavy enough to require two people to mount them." Raymond Hey - Tuesday, October 8, 2024
WOW- good price!
"what a good price on a 2 zone rates at -13F!" William Sanchez - Monday, August 19, 2024
