Sourcing MRCOOL DIY Series Systems
HVACProSales helps contractors, property managers, and procurement teams source MRCOOL DIY Series systems for residential retrofits, new construction, garage conversions, sunrooms, ADUs, and light commercial spaces. The DIY Series is one of the most recognized ductless mini-split lines in the North American market due to its pre-charged line set design, which reduces installation time and eliminates the need for refrigerant recovery equipment on initial installation. Contractors use the DIY Series for applications where a quick, clean installation is a priority. Property managers and facility teams use it for tenant comfort upgrades, server rooms, and supplemental cooling in spaces that cannot be served by central ductwork.
