DIY Mini Split Systems
DIY mini split systems are changing how homeowners approach heating and cooling. Designed for simple, tool-free installation, MRCOOL’s innovative DIY series eliminates the need for vacuuming or charging refrigerant lines—making professional-grade comfort more accessible than ever.
Each DIY system arrives pre-charged with R-410A refrigerant and includes quick-connect line sets that snap together without specialized HVAC tools. That means no cutting, no brazing, and no vacuum pump. Homeowners can install the entire system with basic hand tools, following clear step-by-step instructions.
DIY mini splits are ideal for garages, offices, bedrooms, workshops, and home additions—anywhere traditional ductwork would be too costly or complex. SEER ratings range from 18 to 22, meaning you’ll enjoy lower utility bills while maintaining a consistent, quiet, and comfortable environment year-round.
Each MRCOOL DIY system includes smart-control options for Wi-Fi and app-based operation, built-in heat pump functionality for both cooling and heating, and multi-zone configurations supporting up to five indoor air handlers. When properly installed, these systems deliver exceptional efficiency and reliability backed by manufacturer warranty coverage.
For best results, ensure your electrical supply matches the unit’s requirements, mount the indoor unit securely, and follow all installation steps carefully. A DIY system lets you save on labor while gaining complete control over your home’s comfort—an ideal blend of performance and accessibility.
