Cooper & Hunter MIA 12,000 BTU

Three concrete things: the Wi-Fi module is built in rather than a plug-in dongle, the compressor warranty runs 7 years versus 5, and the 21.2 SEER2 matches the LETO exactly — unsurprising since both are Midea-built hardware. If app control matters to you, the MIA is effectively the cheaper unit once you price in Senville's kit.

Mediocre: 8.7 HSPF2 with a 5°F operating floor makes it fine for shoulder seasons and mild winters but a poor primary heater. Buy it for its cooling efficiency and treat heating as a bonus; cold-climate buyers should look at hyper-heat class units instead.

The MIA has C&H's GoldFin anti-corrosion coil coating, specifically aimed at humid and coastal environments where bare aluminum fins pit and fail early. It's not invincibility, but it's a real advantage over uncoated budget units for salt-air exposure.

Strict ones: registration within 30 days plus licensed installation for the full 7-year compressor / 5-year parts coverage. Owners also report slow warranty parts shipments, so factor patience into any claim. One more caveat: C&H renames its series frequently, which can complicate matching parts to your exact model years from now — keep your full model number documented.

A standard flare-and-vacuum job — precharged R454B with a 16-ft install kit in the box, on a dedicated 115V circuit (15A max fuse class). It's current-generation refrigerant with AHRI-certified ratings, and C&H lists it as IRA 25C-eligible, so check whether the tax credit applies to your install.
