Our takeThe Diamante we'd buy: 74% of its rating at 5°F, ENERGY STAR Cold Climate, and a warranty that doesn't demand a licensed installer. It needs a nitrogen-assisted evacuation and stops heating at -4°F.Same NEEP heat as the 12K at every temperature with 33.3 SEER2; the efficiency pick if 9,000 Btu/h of cooling is enough.

Watch out forThe older R-410A Diamante Pro Series ends FI19RL (heats to -13°F, 19 SEER2 on the 12K 115V); confirm SI20RL or R-454B. The Diamante Essenza, Diamante Ultra and WYS are different lines with different specs. Registration deadline reads 90 days on the product page and one week after install in the warranty policy; satisfy both.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. Senville's 22.0 HSPF2 for the 9K is far above its AHRI certificate (14.6).
