Our scoreSCORE6.4 / 10SCORE6.9 / 10
Our takeThe biggest Leto, keeping 59% of its rating at 5°F. A cooling-first choice for a large zone.The most heat in the line at -13°F, but it is a lot of unit for a garage, gives up efficiency and carries neither ENERGY STAR label.

RefrigerantR-454BR-454B
Watch out forAmazon 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.MRCOOL also called its older R-410A 4th Gen DIY "E Star"; confirm R-454B and a model number of the form DIY-...D25-O. DIYS- is the cheaper DIY Select and EZPRO- is the Easy Pro; a listing that says "5th Gen" and "Select" is the Select. The manual says the line sets install once; reconnecting them, or the pipes at the outdoor unit, voids the warranty.
