I recently completed the installation of a Mitsubishi MZ-GL09NA mini-split air conditioning system in a garage that was being converted into a dedicated gaming room. The homeowner wanted a high-efficiency, ductless solution to provide precise temperature control for the space. I carefully mounted the wall-mounted indoor unit and outdoor condensing unit, charged the R410A refrigerant, and connected the electrical and condensate drainage. The system is now operating smoothly, keeping the gaming area comfortably cool.
