Why it matters
The ROVSUN 4-Zone (12K+12K+12K+12K) 38,000 BTU 230V Mini-Split is rated at 38,000 BTU of cooling. It splits that capacity between 4 indoor heads, so size each head to its own room and check the total against the condenser. It needs a 230V (208/240V) circuit, which usually means an electrician if one isn't already at the spot.
Its 20 SEER2 ranks 2 of 3 among the multi-zone systems within about 12% of its capacity that we cover; the most efficient is the Albott 3-Zone (12K+12K+12K) 36,000 BTU 230V Mini-Split at 22. 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 28 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. The kit includes a 25Ft Line Set. It uses R-32 refrigerant, one of the lower-impact A2L refrigerants new systems moved to in 2025. Warranty, per the listing: 1 Year Warranty.
The kit pairs the condenser with a 12,000 BTU head (about 450-550 sq ft), a 12,000 BTU head (about 450-550 sq ft), a 12,000 BTU head (about 450-550 sq ft) and a 12,000 BTU head (about 450-550 sq ft), so each room should fall in its head's band. The listing gives dimensions of 18.42 inD x 42.28 inW x 33.58 inH, a shipping or unit weight of 250 pounds, a 3,600 W power draw and remote in the box.
