Does it need a special electrical circuit?

Yes. It runs on 208/230V at about 9 amps, so it needs a dedicated circuit and breaker, not a standard wall outlet.

Can it heat as well as cool?

It is a heat pump, so it provides both cooling and heating. Heating output drops in very cold weather, as with any standard mini split.

How large a room will it cool?

The rating is up to about 1,000 square feet. Insulation, ceiling height and sun exposure change the real result.

Does it work with a phone app?

No. Control is through the included button remote and indoor unit; there is no Wi-Fi or smart-home support.

What comes in the box?

Indoor and outdoor units, the remote and basic mounting hardware. Line sets and wiring are usually bought separately.

Who should install it?

A licensed HVAC technician. It needs vacuuming, refrigerant line work and electrical hookup that most homeowners cannot do safely.

Our take on the Lithzen 18,000 BTU 18.2 SEER2 Mini Split Air Conditioner & Heater

The Lithzen 18,000 BTU is a ductless split system that both cools and heats, rated for rooms up to about 1,000 square feet. It runs on 208/230V and claims an 18.1 SEER2 rating, 530 CFM airflow and a low 23 dB indoor noise level. Buyers get seven cooling settings and six fan speeds, plus a wired button control. It is a budget-tier brand, so expect fewer smart features and thinner dealer support than Mitsubishi, Daikin or Fujitsu units at the same capacity.
