OLMO 36K-9K+9K+9K+12K Quad Zone Wall Mount Ductless Mini Split A/C and Heater: Smart port adapters for individual control
Meet the Olmo Multi SIERRA Series—your go-to for wall-mounted mini split air conditioners that don't just cool but also heat, making them perfect for year-round comfort. Whether you're battling the summer heat or just need a bit of warmth in winter, these inverters have got you covered. And with models ranging in BTU, there's one for every space. Plus, they're not just powerful; they're smart too, boasting up to 21.0 SEER2 efficiency and AHRI certification. (Yeah, they're kind of a big deal.)
But wait, there's more! Olmo throws in a digital remote (because who likes getting up to adjust the temp?), a timer because timing is everything, auto louver swing for that perfect breeze, and an LED display that's actually easy to read. And for those who love tech, the Smart Connect feature is a game-changer—control your AC from your phone, because why not?
Oh, and the remote? It's like the Swiss Army knife of remotes with Sleep Mode (for those perfect night's sleeps), Timer (set it and forget it), Turbo and Eco modes (for when you need power or savings), and a Self-cleaning mode (because nobody has time for maintenance). And let's not forget the compressor units—affordable, reliable, and thanks to Inverter Technology, they'll save you more energy (and money) than those old-school compressors. Basically, it's like having your cake and eating it too.

I was EXTREMELY skeptical when I bought this on impulse, thinking it might be another overhyped gadget, but WOW, the reality blew my expectations out of the water. In Seattle's unpredictable weather, this thing keeps our home comfortable year-round without breaking the bank. Compared to other units in the same price range, it's way smarter and more reliable. The only downside is the initial setup headache, but once it's running, it's pure magic. I'd recommend it to anyone, especially busy parents like me who need things to just work.
- Pros: It heats and cools my whole house efficiently, saving a ton on energy bills compared to my old unit. The remote and phone app make it super easy to adjust settings without getting up, and the self-cleaning feature is a lifesaver for someone with no time for maintenance. The air flow feels just right, not too harsh, and it's quiet enough that it doesn't disturb our sleep.
- Cons: The installation was a bit of a hassle and cost more than I expected, and the manual was completely useless—I had to figure everything out myself. Sometimes the app glitches and doesn't connect properly, which is frustrating when I'm trying to control it from another room.
