A ceiling cassette is an indoor air handler that is recessed into the ceiling, showing only a decorative grille. This is a popular choice for those browsing our Ceiling Cassette Multi-Zone collection. Units like the MRCOOL Olympus Cassette 18,000 BTU provide 360-degree airflow for superior coverage. They are ideal for commercial spaces or modern homes where wall space is limited. The built-in drain pump helps manage condensation effectively even from a ceiling position. It offers a sleek, professional look that blends into any decor.
