Experience Precision Climate Control Right Now

After installing and living with the JustSmart 9000BTU Mini Split for several weeks, we can say it’s more than just a ductless AC – it’s a true all-season comfort solution. Whether you’re battling summer’s heat or winter’s chill, this wall-mounted unit delivers swift, whisper-quiet performance, smart connectivity, and energy savings that really show up on your utility bill.

Key Features That Made Us Fans

• 18.5 SEER2 Efficiency: During our hottest afternoons, the unit dropped room temperature from 80°F to 72°F in under 10 minutes, all while drawing minimal power.
• 9,000 BTU Cooling & Heating: Perfectly sized for spaces up to 450 sq. ft., it kept our living room and guest bedroom consistently comfortable.
• Wi-Fi & Alexa Integration: Adjust settings remotely via the JustSmart app or simple voice commands. We turned the heat on from the grocery store and stepped into a cozy home minutes later.
• Complete Installation Kit Included: Condensate pump, line sets, mounting bracket, and all fittings are in the box. Our DIY installation took approximately 2.5 hours from drywall to powered-on.
• Ultra-Quiet Operation: At just 24 dB in low-fan mode, it’s quieter than a whisper—ideal for bedrooms, home offices, or nurseries.
• 4-Mode Fan & Dehumidification: Choose from Auto, Cool, Heat, Dry, and Fan modes. The Dry setting removed excess moisture overnight, cutting humidity by 15% in our test room.
• Smart Diagnostics & Auto-Restart: If the power blips, it automatically resets to your prior settings, ensuring uninterrupted comfort.

Why We Recommend the JustSmart Mini Split

From our first powering-on moment, the JustSmart unit felt thoughtfully engineered. The sleek indoor panel blends into any décor, and the magnetic air filter is a breeze to clean. We appreciated the step-by-step installation guide—no hidden parts or last-minute hardware runs. And once it was up and running, the precise temperature control and allergy-reducing filtration made a real difference in air quality.

Transform Your Space in Minutes

Whether you’re converting a finished basement, upgrading a rental property, or creating a dedicated home office oasis, this mini split delivers professional-grade performance with minimal fuss. We’ve tested bigger brands, and at this price point, JustSmart offers comparable efficiency and far more user-friendly setup.

Smart Home Ready—Control from Anywhere

We connected the unit to our home network in under 3 minutes. The JustSmart mobile app gives you full control: temperature schedules, Eco mode, energy-use reports, and real-time alerts if filters need cleaning. Linking with Alexa meant our kids now argue over who gets to cool (or heat) their room first.
