Cooper & Hunter MIA 12,000 BTU

The Sophia is C&H's flagship wall-mount series and the more popular of the Sophia/Olivia pair — sold through Home Depot, Amazon, and dealer sites for years. Reviewers widely identify it as Gree-built hardware, which is a genuine step up in fit-and-finish: double-level air flaps, 12 fan speeds, 'I Feel' remote temperature sensing, and Wi-Fi on current listings. Its standout spec is the -13°F rated heating floor — unusual under $1,000 and the reason it shows up in mild-winter primary-heat conversations where a LETO wouldn't. Heating efficiency documentation is thin, though: C&H publishes a Region-V HSPF2 of 7.6 (the harsher rating region) and no prominent Region-IV figure, so it looks worse on paper than rivals quoting Region IV. Home Depot reviews are the usual budget mix — most owners happy, a vocal minority describing frustrating warranty claims. It's still R410A in most stock, worth noting as that refrigerant's phaseout raises future service costs.

The cheapest complete dual-zone system in this roundup — about $1,340 gets you the condenser, two 9k Olivia wall heads, 25 ft line sets, and Wi-Fi dongles. C&H is a Gree-adjacent import brand that r/hvacadvice treats as serviceable budget gear: fine when installed carefully, frustrating when you need parts or English-language support in year six. The multi-zone caveats hit harder at the budget end. One compressor backs both rooms, so a failure is a whole-system outage, and an 18k condenser answering a single 9k call cycles more than two separate singles ever would — two C&H 9k singles actually cost about the same and sidestep both problems if you can mount two outdoor units. It's also still on R410A, which is being phased down, so think about long-term refrigerant availability. Heating output holds a claimed 12,600 BTU at 5°F with operation to -13°F — usable shoulder-through-cold performance, but not a true hyper-heat machine for design-day heating in the north.

First, a correction to the shopping list: Della doesn't make a 'Voltra' — its 12k lineup is the JPB, Vario, Motto, Serena, and Umbra series. We've listed the Home Depot JPB (20 SEER2, 115V, ~$850) as the representative unit. Della is the cheapest way into a name-brand-ish 12k heat pump, and owners genuinely like the cooling performance, quiet operation, and app for the money. But it is not a true DIY unit: the lineset isn't precharged or quick-connect, so you're flaring, evacuating with a vacuum pump, and leak-testing like a pro would — Della's own tool-rental program is the tell. Reddit and Amazon feedback is classic budget-brand: most units run fine for years, but when one doesn't, support is slow, and the lifetime-parts warranty requires registration within 100 days and gets watered down for self-installs. Heating stops at 5°F, so treat it as a cooling-first unit with shoulder-season heat. Buy it for the price, not the install experience.
