Our takeThe weakest cold-weather size in the line at 54% of its rating at 5°F; the DIY 5th Gen 18k makes 12,800 there and double the heat at -13°F.Full rated output at 5°F, matching the Olympus E Star 18k value for value, and it cost less than the Amazon Olympus when we checked. Licensed install required.

Watch out forThe earlier Easy Pro (outdoor suffix 11516D-O or 23016D-O, 16 ft kit) carries 1 yr parts / 2 yr compressor and needs an authorized-dealer purchase. Some Amazon titles say "5th Gen" and "16ft Lineset"; read the suffix. Current version outdoor units end 11511DE-O (9k/12k) or 23011DE-O (18k/24k). The warranty's definition of parts excludes line sets, and the quick-connect valves are one-time install.The Amazon 18k listing gives 2 yr parts / 7 yr compressor; confirm the term for the model you receive. 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.
