The MrCool DIY Ceiling Cassette is perfect for any space and provides discreet and out-of-sight heating and cooling. It is available in single-zone (18K BTU only) and multi-zone options (9K, 12, 18K) and is easy to install, fitting between 16” ceiling joists.

The cassette is designed to work with both current and future joist standards and can be recessed between all types of joists on 16-inch center, including pre-manufactured I-joists. Other ceiling cassettes have strict installation requirements in less ideal locations, but the MrCool® cassette doesn't require ductwork.

It is also quite adaptable, with numerous operating modes including COOL, HEAT, AUTO, DRY (dehumidify), and SLEEP. This unit can also be operated by your Apple or Android smartphone via the Smart HVAC app.

This cassette is designed to be used with MrCool's proprietary Pre-Charged Quick Connect Line Set, which further simplifies installation. The line set includes fast connectors, which allow a do-it-yourself installation to connect the refrigerant piping with wrenches. 

The line set is pre-charged with the exact amount of R-410A refrigerant at the factory, so no vacuuming is required. 

You can buy line sets and couplers here.
