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.
