Our take on the Mr. Cool DIY 24,000 BTU 5th Gen Multi-Zone Wall Mounted Indoor Unit

This is the indoor wall-mounted air handler of MRCOOL's 5th Gen DIY multi-zone system, rated 24,000 BTU for spaces up to about 1,000 sq ft. It is built for owner installation: it pairs with a pre-charged Quick Connect line set that uses R-454B refrigerant, so no vacuuming or brazing is needed. Control comes from a remote, the SmartHVAC app and Alexa or Google Assistant, with Follow Me airflow and a Dry mode for humidity. Against pro-installed brands it trades some efficiency and refinement for self-installation and a strong warranty; owners of the DIY line praise the easy hookup and quiet operation but note the line set is sold separately and the unit is large on the wall.
