OLMO 42K-9K+9K+9K+9K+9K Five Zone Wall Mount Ductless Mini Split A/C and Heater: Smartphone remote control via OLMO Remote app
Meet the Olmo Multi Sierra Series wall mounted mini split air conditioner—your go-to for multi-zone cooling and heating that doesn't quit, no matter the season. 🏡 With a range of BTU models to choose from, these inverters aren't just powerful; they're smart, hitting up to 21.0 SEER2 and backed by AHRI certification. Imagine controlling your comfort with just a click, thanks to the digital remote, or setting it and forgetting it with the timer function. And with features like auto louver swing and an LED display that actually makes sense, upgrading your space (home or office) just got a whole lot easier.
But wait, there's more. Olmo's 'Smart Connect' turns your phone into the ultimate remote—because who loses their phone? (Okay, don't answer that.) 📱 Dive into Sleep Mode for those perfect night's sleeps, flip on Turbo when you need a quick cooldown, or let Eco mode keep your bills in check. And with Self-cleaning mode, it practically takes care of itself. Thanks to Inverter Technology, it's kinder to your wallet and the planet, and Whisper Technology means it won't drown out your thoughts (or your shows). Perfect for anywhere you need a little peace and quiet.
Worried about setup? Don't be. Each air handler comes with an Installation Kit that's got pretty much everything—25ft of pre-flared, insulated copper line, communication wires, and all the little bits and bobs. 🛠️ Just remember, this isn't a DIY weekend project; you'll need a pro to handle installation. And because these units aren't exactly featherweights, they're shipped freight with lift-gate service. So, no heavy lifting on your part—just cool, comfortable air waiting to happen.
