Our takeThe weakest version of the quick-connect idea: 6,200 BTU/h at 5°F, an 11.5 ft line set and 1 year on parts. Buy it only if the budget leaves no other choice.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 forMRCOOL's naming is inconsistent: its product data says "DIY Select 1st Gen" while the warranty is titled "5th Generation DIY Select Series". A "5th Gen" listing that says "Select" is this cheaper line. Model numbers start DIYS- (outdoor ends A11-O, wall unit A13-O); DIY- ...D25-O is the DIY 5th Gen. ENERGY STAR status conflicts: MRCOOL's catalog says certified, MRCOOL's product data and NEEP say no.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.
