Each unit fits discreetly between standard 16" joists – including pre-manufactured I-joists – ensuring hassle-free installation and maximum flexibility for your projects. The innovative "Elevation" feature allows easy access to air filters with just a touch of the remote, simplifying maintenance for your clients.
What truly sets this system apart is MRCOOL's revolutionary pre-charged line set technology. Each of the three included 25-foot copper line sets comes pre-filled with R-410A refrigerant, eliminating the need for specialized vacuum equipment or certified technicians.
