Our takeThe size we'd look at first for a garage on a 230V circuit: 12,800 BTU/h at 5°F and more heat at -13°F than the 24k. We don't have a verified Amazon listing for this size.The strongest Elite relative to its size: 22,600 Btu/h at 5°F and 11,900 max at -22°F.

Watch out forMRCOOL 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.Senville's FAQ says no to owner installs; warranty registration asks for the installing company and invoice. Senville's site lists higher HSPF2 than the AHRI figures on NEEP; we use the certified numbers. The Amazon 18K listing model field reads SENE-12EL-16 while the part number is SENE-18EL-16.
