Single-Zone Mini-Splits

One condenser, one wall head, one room handled properly — single-zone systems are the biggest, most competitive slice of the market, from $700 Amazon-brand units to $2,500 Japanese flagships. This is where the value brands (Senville, Pioneer, Cooper & Hunter — mostly rebadged Midea and Gree hardware) undercut Mitsubishi, Daikin, and Fujitsu by two-thirds on equipment price. The honest catches: these need a real install — flared connections, evacuation, a vacuum pump — and most HVAC contractors won't touch equipment you bought online, so get the install plan settled before the unit ships. Budget brands also mean importer warranty support and slower parts, which matters more when the unit is your primary heat.

The catalog has 87 single-zone mini-splits from 17 brands, priced from ~$600 to ~$5,121. 2 are rated to keep heating down to -31°F, the least expensive being the LG Art Cool Deluxe LGRED 9,000 BTU. The cheapest way in is the ROVSUN 12,000 BTU at ~$600.
