Our takeUp to four heads and 18,200 Btu/h at 5°F, enough for a typical bedroom floor. Condenser only on Amazon; buy matching 5th Gen heads separately.For a big open zone in a cold climate with a contractor doing the install: 24,200 BTU/h at 5°F. Its high minimum output rules out single rooms.

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. NEEP lists its 17°F rating (16,200) below its 5°F rating (18,200).Senville's 24k page shows a ceiling-cassette spec table, so these figures come from NEEP only. The Amazon 24k listing (SENA/24HF) doesn't state refrigerant; confirm the model before you pay. The Amazon Aura listings don't state refrigerant. The 12k listing (SENA-12HF-16) shows a 25.5 efficiency figure that matches the older R-410A Aura and a 2 yr parts / 7 yr compressor warranty field; confirm model and refrigerant before you pay. Current R-454B wall pairings are SENA-xxHF-OG + SENA-xxHF-IGG; older R-410A pairings end /OQ + /IQ. Senville's site lists higher HSPF2 and 47°F heat than the AHRI figures on NEEP; we use the certified numbers. Senville's FAQ says no to owner installs, and the warranty requires a licensed HVAC contractor.
