MRCOOL DIY 5th Gen E-Star Series 18K BTU, 1.5 Ton, 21.5 SEER2 Ductless Mini-Split Heat Pump System with Ceiling Cassette Air Handler – R-454B vs MRCOOL DIY Easy Pro 18,000 BTU Mini-Split

Both are 18K BTU MRCOOL DIY heat pumps, so the real split is form and efficiency. The 5th Gen E-Star ceiling cassette is the better system on paper: higher 21.5 SEER2 efficiency, R-454B refrigerant, and a flush ceiling mount that keeps the wall clear and spreads air in four directions. The Easy Pro is the simpler, proven wall unit with a strong 4.8-star owner rating and a pre-charged line set, but its 18.5 SEER rating and 60 dB rating trail the cassette. Buy the cassette for a remodel or a room where looks matter; buy the Easy Pro for a straightforward wall install.

• Choose the MRCOOL 5th Gen E-Star ceiling cassette if you want the highest efficiency, a flush ceiling look, and four-way airflow in a room with standard 16-inch joists.
• Choose the MRCOOL Easy Pro if you want a conventional wall-mounted unit with a long track record of owner satisfaction and a simple pre-charged install.
