ACiQ has quietly built a reputation for delivering capable, no-fuss mini splits. This 12,000 BTU model is a straightforward example: a single-zone unit that handles both cooling and heating for a room up to about 550 square feet. Its core appeal is a simple, effective package that includes the essentials, like a 16-foot line set, right in the box.

At 19 SEER2, it operates efficiently, which translates directly to lower electricity bills over a season. The inverter compressor adjusts its speed instead of just cycling on and off. You feel this as a consistent, even temperature without sudden blasts of cold air. The indoor unit runs at a quiet 28 decibels on low—about the level of a whisper. Controlling it is simple via the included remote, and the optional WiFi module lets you adjust settings from your phone.

Installation is not a DIY project and requires a certified HVAC technician for the refrigerant lines and electrical hookup to its 230V circuit. But having the core installation kit included eliminates guesswork for your pro. This unit is a pragmatic choice for converting a sunroom, cooling a home office, or making a finished garage usable year-round.
