Is $597.99 a good price for this mini split?

It is the best new price among the four stores listing it as of November 6, 2026, and it is low for an 18,000 BTU R454B inverter system. Expect to add the line set and installation labor on top.

What size room will 18,000 BTU cool?

About 1,000 sq ft in a typical well-insulated space. Hot climates, vaulted ceilings or poor insulation call for a smaller area or a larger unit.

Does it heat in winter?

Yes. It is a heat pump rated at 18,800 BTU heating and operates down to 5°F outdoor temperature, though capacity falls as it gets colder.

What electrical supply does it need?

208/230V single-phase, 60 Hz, with a 15 A minimum circuit ampacity and a 20 A maximum fuse. It does not plug into a standard 120V outlet.

What comes in the box?

The outdoor condenser, the wall-mount indoor unit, an IR remote, and the Wi-Fi Smart Kit. The line set, communication cable and drain line come as a 16, 25 or 50 ft installation kit.

How long a line set can it use?

Up to 98.4 ft of pipe. The condenser is precharged for 25 ft, so longer runs need additional refrigerant.

What reviewers say

Owner feedback on the MIA series centers on quiet indoor operation and steady inverter output, with installers noting the precharged line set simplifies setup. Complaints tend to involve the electrical requirements and the cost of professional installation rather than the unit itself.

EfficiencyPraisedThe 19.2 SEER2 rating and inverter compressor are cited as reasons for low running costs.
InstallationMixedThe precharged 25 ft line helps, but buyers note a licensed installer and 230V circuit are still required.
HeatingMixedHeating works well in mild cold but output tapers as outdoor temperatures approach 5°F.
Wi-Fi controlPraisedThe included Smart Kit and app make scheduling and remote control straightforward.
