The Costway 18000 BTU Mini Split is a single-zone wall-mounted heat pump that cools and heats up to about 1,250 sq ft. Its 21 SEER2 rating and 1.5-ton capacity put it in line with name-brand inverter splits, and it runs as quietly as 28 dB on low. It has eight fan speeds, a washable filter and a claimed heating range down to -4°F. It suits homeowners adding zone comfort to a large room or open plan without ductwork. The catch is that it is a budget-brand unit sold without a licensed installer network, so warranty support and parts availability are weaker than Mitsubishi, Daikin or LG, and the line set and mounting hardware are basic.
