Why Choose the MRCOOL DIY® Mini-Split System?
Effortless DIY Installation
Unlike traditional HVAC installs, the MRCOOL DIY® uses pre-charged Quick Connect® line sets, so you won’t handle refrigerant or pull a vacuum. Most homeowners complete setup in a few hours—the perfect weekend upgrade.
Energy Efficiency That Saves
Advanced inverter technology matches output to demand for steady comfort and lower utility bills. Efficient operation means less waste and more savings.
Zoned Comfort for Every Room
Control temperatures room-by-room so each space feels just right. From a quiet bedroom to a busy living room, zoned comfort reduces energy use and eliminates hot and cold spots.
How to Install the MRCOOL DIY® Mini-Split
- Choose the perfect spot. Mount the indoor unit at a comfortable height; place the outdoor condenser on a level, well-ventilated surface.
- Drill the connection hole. Create a small wall opening for the pre-charged refrigerant lines, communication cable, and drain hose.
- Connect the lines. Feed tubing and wiring through the sleeve and tighten the Quick Connect® fittings—no vacuum pump required.
- Power it up. Restore power, follow the quick-start, and use the remote or the MRCOOL Smart HVAC App to set your ideal temperature.
- Enjoy your comfort. Sit back and enjoy quiet, efficient heating and cooling—installed by you.
Tip: Plan the condensate drain route and confirm clearances before drilling for the cleanest, most reliable install.
