Why it matters
The DELLA Umbra 23,000 BTU 230V is rated at 23,000 BTU of cooling and 24,000 BTU of heating. On the ENERGY STAR room sizing chart that suits about 1,200 to 1,400 sq ft of average room; the maker says up to 1,500 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 6 of 11 among the mini-splits within about 12% of its capacity that we cover; the most efficient is the Cooper & Hunter 24,000 BTU 230V Mini-Split at 23.5. 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 30 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. Warranty, per the listing: Lifetime coverage.
The listing gives dimensions of 9.13 inD x 44.57 inW x 12.99 inH, a shipping or unit weight of 30.9 pounds, a 2,100 W power draw and user manual in the box.
