Why it matters
The Senville 4-Zone 36,000 BTU 230V Mini-Split is rated at 36,000 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 22.5 SEER ranks 1 of 2 among the multi-zone systems within about 12% of its capacity that we cover, the top of that group. 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 23.5 dB at its quietest setting.
Like most split systems it ships pre-charged for a set line length; connecting it means flaring, pulling a vacuum and opening the valves, a licensed technician's job in most places. It uses R-454B refrigerant, one of the lower-impact A2L refrigerants new systems moved to in 2025. Warranty, per the listing: Manufacturer warranty is 10 years on the compressor and 5 years on all other parts. Technical Support is available 5 days a week.
The listing gives dimensions of 48 inD x 40 inW x 60 inH, a 10,559 W power draw and indoor air handlers (4), outdoor condenser, 16ft. installation kit with line set and communication wire in the box.

Pros and cons
Pros
- 22.5 SEER
- Quiet indoor head (23.5 dB)
Cons
- Low-temperature heating not stated
- Needs a 230V circuit
- Professional install recommended
Limitations to weigh
- Capacity and efficiency are the maker's ratings; real output depends on the install, the line length and the weather.
- Heat pumps lose heating capacity as it gets colder; size for your climate with the BTU calculator.
- The federal 25C tax credit ended for systems installed after 2025; check your utility for current rebates.
