I put this in a room that was always either too hot or too cold, and it honestly fixed the problem right away. It has been quiet, easy to use, and way better than the window unit I had before.
on the Zone Air 2-zone mini split system →As an HVAC contractor I've installed my fair share of dual-zone systems - and this one is an excellent value. The build quality is rock solid, the installation is pretty DIY-friendly with the pre-charged lines, and customers just love the independent zone control. The 24 SEER2 rating means real energy savings, not just some pie-in-the-sky promise.
on the Zone Air 2-zone mini split system →Installing two units in our open plan office - one for the main work area and one in the conference room. The 360° airflow keeps everyone comfortable no matter where they sit. Having independent control lets us cool down the conference room when the big meetings are happening. Plus the units look super professional.
on the Zone Air 2-zone ceiling cassette mini split →I installed one unit in the master suite (bedroom, bathroom, closet) and another in the main living areas (living room, dining room, kitchen). The only stuff you can see are some small linear vents - and that's it. You'd never even guess there's a mini-split system back there. Each zone stays exactly the right temperature on its own.
on the Zone Air 2-zone concealed ducted mini split →We needed some new heating and cooling for our 1890s Victorian, but we wanted to keep the place looking historic. These units got installed in the attic with little ducts going to these tiny ceiling vents - and the original plaster and trim are completely untouched. It operates super quietly and handles our crazy New England winters like a breeze.
