ACiQ 12,000/18,000 BTU Slim Ceiling Cassette Mini Split Air Handler

Slim Ceiling Cassettes give you the advantages of a traditional cassette, but in a slimmer profile designed to fit between 16”-on-center joists. This means an easier installation in many cases.

Slim Ceiling Cassettes have a one-way air delivery, taking in return air along one edge and delivering conditioned air out the other. Traditional ceiling cassettes send conditioned air out in 4 directions and take return air in at the center.

Slim Ceiling Cassette air handlers provide the same high-efficiency heating and cooling of a regular wall-mounted unit and come with a hand-held remote control. Once mounted in the ceiling, only the grille is visible for the most understated appearance.

Switchable Sizing

  • ACiQ-SCC1218 – 18,000 BTU default, switchable to 12,000 BTU by changing the dip switch

Installation Considerations

Slim Ceiling Cassettes are flush-mounted, which requires removal of enough ceiling material to create a cavity for the unit. The Slim Ceiling cassette is designed to fit between 16” on center joists, and the narrow profile means no changes to your framing will be required in most cases. Additionally, Ceiling Cassettes have factory-installed, onboard condensate pumps to lift the condensation up to 14 inches. From there, it will be necessary to construct a PVC drain system to route the condensation to a safe wastewater location. Refrigerant and wiring connections are the same as the wall mounted units.


  • Narrow profile fits between 16 inch-on-center joists
  • Switchable size – select between 12,000 BTU and 18,000 BTU
  • No-ladder filter cleaning – grille lowers on cables for easy access to filter
  • Handheld remote included
  • Decorative Grille included
