Our scoreSCORE6.3 / 10SCORE6.8 / 10
Our takeA whole-house condenser: six heads and 37,000 Btu/h at 5°F. Its 13,000 Btu/h minimum makes it a poor match for a house of small rooms.Up to five heads and 36,000 Btu/h at 5°F, but a 10,000 Btu/h minimum overshoots small rooms on mild days. Pro install.

Watch out forThe 4th Gen multi-zone (C suffix, R-410A) is a different system; its 18K ran two zones, not three. On earlier generations owners report idle heads still heating or cooling and rooms overshooting setpoint; there is no long 5th Gen record yet. Line sets are one-time installs; runs past the standard 24.6 ft per head and ducted (AHU) air handlers call for added refrigerant per the manual. Sold on Amazon by a third-party seller in small quantities; condenser only, heads and line sets sold separately.MOA outdoor units are listed as R-454B on Senville's pages and NEEP; NEEP lists the MOB units as R-410A, and an owner of an earlier SENA-28HF-MOA reports R-410A. Confirm the refrigerant on the label. Senville's FAQ says owner installs are not supported; the warranty certificate requires a licensed professional, and labor is never covered.
