COZEWARE Visio Series 18000 BTU 20 SEER2 Ductless Mini Split AC with Heat Pump, 230V – 4D Airflow, 1250 Sq Ft Coverage, WiFi & Voice Control, R32 Refrigerant

Between a single bedroom and a whole open floor plan, there's a mid-size gap that a lot of mini split lineups skip over — this 18,000 BTU unit is COZEWARE's answer for it, rated to cover up to 1250 sq ft, which fits a large living room, a finished attic, or a couple of connected rooms without stepping all the way up to the 24,000 BTU model. 4D sweeping airflow keeps the added capacity from just blasting the area nearest the unit, distributing air more evenly across the larger space instead.

At 20 SEER2 and 8.5 HSPF2, it's built for roughly 30-40% energy savings over less efficient equivalents, and it runs at 36 dB — noticeably present at this capacity, but still quiet enough not to dominate a room. R32 refrigerant and AHRI/ETL certification carry over from the rest of the Visio Series, as does app and voice control for remote scheduling and adjustment. If the 12,000 BTU size feels like it would be stretched thin in your space but the 24,000 BTU unit is more capacity than you need, this is the size built to sit right in between.
