Our takeThe strongest Elite relative to its size: 22,600 Btu/h at 5°F and 11,900 max at -22°F.A capable heat pump on paper but a superseded R-410A generation that cost more than a Senville Aura 18k when we checked. Buy it only with an installer who will commission R-410A.

Watch out forSenville'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.Amazon lists model O-HH-18-HP-230E and no refrigerant; its "20 SEER" matches the 2022 R-410A O-HH-18-HP-C-230. The no-suffix model has no NEEP listing we could find. The legacy warranty applies only to installs by a state certified or licensed HVAC contractor. R-410A parts may be hard to find; one owner couldn't source a matching MrCool wall unit.
