Spec Senville Leto 12,000 BTU 115V MrCool Olympus E Star 4th Gen 12,000 BTU Photo Our score SCORE 6.4 / 10 SCORE 7.4 / 10 Our take A cooling-first unit that also heats: 21.2 SEER2 but only 6,600 BTU/h at 5°F, 55% of its rating. Buy it for mild winters with a licensed installer. About 96% of its rating at 5°F and heat published to -22°F, among the best cold numbers we cover. Budget a contractor, because it isn't a DIY unit.

Amazon Leto listings don't state refrigerant; current R-454B pairings are SENL-xxCD-OL + SENL-xxCD-ILL, older R-410A ones end /OY + /IY. Senville's FAQ says no to owner installs, and the warranty requires a licensed HVAC contractor. "E Star" and the O-ES prefix also appear on an older R-410A Olympus (-230B condensers); confirm R-454B and an outdoor model ending -230C-O1. The Olympus listings on Amazon are the legacy R-410A Hyper Heat, not this unit. MrCool's FAQ says an HVAC professional must install it; the warranty's softer "may be necessary" wording doesn't change that.
