Why it matters
The COSTWAY 24,000 BTU 230V Mini-Split is rated at 24,000 BTU of cooling and 24,000 BTU of heating. On the ENERGY STAR room sizing chart that suits about 1,400 to 1,500 sq ft of average room; the maker says up to 1,250 sq ft. It needs a 230V (208/240V) circuit, which usually means an electrician if one isn't already at the spot.
Its 18.5 SEER ranks 4 of 6 among the mini-splits within about 12% of its capacity that we cover; the most efficient is the MRCOOL DIY 24,000 BTU 230V at 20.5. The listing doesn't give a low-temperature heating limit, so treat it as a mild-climate heat pump until the maker confirms one. Indoor noise is listed at 23 dB at its quietest setting.
Installation needs the lines vacuumed and the valves opened after the line set is connected; most makers tie the warranty to a licensed installer. It uses R-32 refrigerant, one of the lower-impact A2L refrigerants new systems moved to in 2025. Warranty, per the listing: 2 years Warranty for compressor and 5 years for parts.
The listing gives dimensions of 9 inD x 44.5 inW x 13 inH, a shipping or unit weight of 68 pounds and a 1,200 W power draw.
