The MrCool DIY Easy Pro 9,000 BTU 115V is the better DIY mini-split overall, rated 3.1 to 2.8. The MrCool DIY Easy Pro 9,000 BTU 115V leads on warranty and efficiency. The MrCool DIY Select 9,000 BTU 115V wins on value. The MrCool DIY Select 9,000 BTU 115V costs $238 less ($1,249 vs $1,487).
A middle step between MrCool’s Select and DIY 5th Gen: quick-connect and a fair warranty, but it loses much of its heat in a cold snap. Best for mild winters.
MRCOOL DIY Direct $1,487For mild climates and occasional use, where a low price for a quick-connect unit matters most. The short warranty and weak cold-weather output make it a poor main heat source.
