Customer Reviews
We installed the 12K ceiling cassette in our 550 sq ft conference room & its like night & day - the 4 way air distribution means everyone is comfy, not just the people sitting near the old wall unit. Super quiet too - doesnt even register in meetings.
We wanted some nice and unobtrusive HVAC for our open-concept living space. This ceiling cassette is almost invisible and the air distribution is amazing. No more hot spots by the windows. WiFi control integrates well with our smart home setup.
Installed in our small restaurant dining area - customers stay comfy throughout their meal no matter where theyre sitting. Quiet operation is key - diners can have conversations without being distracted by HVAC noise. Worth every penny.
The ceiling cassette gives such a clean professional appearance compared to wall mounted units. Our architect recommended it for our studio and it looks fantastic. Performance is excellent too - heats & cools evenly across the 580 sq ft space.
The unit itself is great - quiet efficient & the 360 airflow is noticeably better than wall units. My only advice is to plan your installation carefully. You need to have access to the ceiling for the unit and to get the lineset & condensate line in there. We had to do some drywall work, but the end result is well worth it.
