Why it matters
The DELLA Motto 18,000 BTU 230V is rated at 18,000 BTU of cooling and 18,700 BTU of heating. On the ENERGY STAR room sizing chart that suits about 700 to 1,000 sq ft of average room; the maker says up to 1,000 sq ft. It needs a 230V (208/240V) circuit, which usually means an electrician if one isn't already at the spot.
Its 19 SEER2 ranks 9 of 16 among the mini-splits within about 12% of its capacity that we cover; the most efficient is the DELLA Optima 18,000 BTU 230V at 23. The maker says heat-pump heating keeps working down to 5°F outside; below that you need another heat source. Indoor noise is listed at 29 dB at its quietest setting.
Expect a professional install: the copper lines are connected, pressure-checked and vacuumed before the refrigerant is released. It uses R-32 refrigerant, one of the lower-impact A2L refrigerants new systems moved to in 2025.
The listing gives dimensions of 8.82 inD x 37 inW x 12.44 inH, a 3,450 W power draw and remote control, installation kit (16ft copper line, 6.56ft outlet drain pipe), alexa compatibility in the box.
