Spec Senville Leto 12,000 BTU 115V Della Serena 12,000 BTU 115V Photo Our score SCORE 6.4 / 10 SCORE 7.3 / 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. The most 5°F heat of the 115V 12k units we cover, 9,200 BTU/h, with ENERGY STAR Cold Climate status. You still need a vacuum pump or a tech for the startup.

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. The listing says "Pre-Charged", but Della's FAQ says the lines are not pre-vacuumed; it is a flare-and-vacuum install. Della's printed manual says the extended warranty is for professional installation; the current web policy gives registered DIY installs replacement parts at Della's discretion. Screenshot it the day you buy. Della also sells Vario, Optima Pro, Hyper Heat and older R410A lines; most owner reports are about those.
