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.Makes less at 5°F than the 18K (20,000 vs 22,600) and NEEP files it as centrally ducted; the least-documented Elite size.

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 FAQ says no to owner installs; warranty registration asks for the installing company and invoice. Senville's site lists higher HSPF2 than the AHRI figures on NEEP; we use the certified numbers. No published max line length for the 24K; Senville's page lists 24.0 SEER2 / 11.0 EER2 vs 25.0 / 14.0 on NEEP.
