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 $1,599The MrCool DIY Easy Pro 12,000 BTU 115V is the better DIY mini-split overall, rated 3.0 to 2.5. The MrCool DIY Easy Pro 12,000 BTU 115V leads on efficiency and warranty. The MrCool DIY Select 12,000 BTU 115V costs $200 less ($1,399 vs $1,599).
For 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.
