230V Mini Split Systems
230V is the default voltage for any mini split larger than 12K BTU or any multi-zone configuration. Higher voltage means lower current draw, smaller wires, and slightly higher SEER2 than the equivalent 115V model — required for 18K systems and multi-zone bundles. Zone Air 230V systems span wall mount, ceiling cassette, concealed duct, and dual-zone bundle form factors at 9K–18K BTU. All run on standard residential 240V split-phase service, the same circuit type that powers your electric dryer or water heater. Free shipping, pre-charged linesets, 7-year compressor warranty.

230V Mini Splits
230V is the right voltage for any mini split above 12,000 BTU, any multi-zone setup, or anyone who wants the maximum efficiency Zone Air offers. Higher voltage means lower current, smaller wires, and slightly higher SEER2 than the equivalent 115V model. Required for 18K systems and multi-zone bundles.
- ✓Capacities from 9K through 18K BTU on a single head
- ✓Up to 24 SEER2 efficiency (vs 23 SEER2 on 115V)
- ✓Required for multi-zone bundles
- ✓Standard residential 240V split-phase service
- ✓Wall, ceiling cassette, and concealed duct options
Why 230V Matters
230V is the default voltage for any mini split larger than 12K BTU or any configuration with multiple indoor units. The higher voltage halves the current draw at a given wattage, which means smaller wires, smaller breakers, and lower transmission losses in the compressor's variable-speed drive. Every Zone Air 230V system runs on standard residential 240V split-phase service — the same circuit type that powers your electric dryer or water heater.
When to Choose 230V Over 115V
Three cases force the choice to 230V:
- You need 18,000 BTU or more. The 18K wall mount, cassette, and concealed duct systems are 230V-only — there's no 115V option above 12K because the current draw would exceed a standard 15A circuit.
- You want a multi-zone system. Every Zone Air multi-zone bundle runs at 230V. The outdoor condenser powers two indoor heads through one shared circuit.
- You want maximum efficiency. The 230V wall mounts hit 24 SEER2 — about 4% more efficient than the 23 SEER2 115V models. The efficiency edge pays back the electrician fee in 4–6 years at average U.S. electricity rates.
If none of those apply and you want the fastest, lowest-friction install, 115V plug-and-play is the better call.
Form Factors Available at 230V
- Wall mount ($1,999–$2,499) — Easiest install, lowest cost. 9K, 12K, and 18K BTU.
- Ceiling cassette ($2,399–$2,599) — Recessed in a drop ceiling with 4-way airflow. 9K and 12K BTU.
- Concealed duct ($2,499–$2,799) — Fully hidden above the ceiling, condition 2–4 rooms from one head. 9K and 12K BTU.
- Multi-zone bundles ($3,499–$4,999) — Two indoor heads sharing one outdoor condenser, mix-and-match form factors.
Electrical Requirements
Every 230V Zone Air system needs a dedicated double-pole breaker. Single-zone 9K and 12K systems need a 15A breaker; 18K systems and multi-zone bundles step up to 20–30A depending on configuration (specs vary per system — check the product page). The wire run uses 12 AWG copper for 15A circuits and 10 AWG for 20–30A. If your panel has a free 240V slot you can DIY the breaker install; otherwise an electrician typically charges $150–300 to add a new dedicated circuit and takes about an hour.
