Our takeCheaper than the DIY 5th Gen 12k, but it makes 6,700 BTU/h at 5°F to the 5th Gen's 8,400, ships an 11.5 ft line set and a warranty that skips the lines. Fine for a bedroom with the outdoor unit right behind the wall.The Senville to buy for real winters, keeping 96% of its rating at 5°F with heat published to -22°F. Budget a licensed installer, because the warranty requires one.

Watch out forOur link is an IWAE bundle listing that opens on the 12k and doesn't show per-size model numbers; ask the seller to confirm the 11511DE-O suffix. The IWAE 1-year labor warranty is the seller's, not MRCOOL's. The 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 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.
