- Coupler technology is the same trusted, nearly leak-proof design used across all MRCOOL DIY systems
- Simply connect the extension to your included 16' line set—no vacuuming or specialized tools required
- Control wire must also be swapped for the longer wire provided in the bundle
- You may coil excess wire or trim to length if you have the technical knowledge

Had a small question during installation and Vanessa picked up right away. They walked me through it step by step — best customer service I’ve had in years.

DIY-Friendly Installation
Designed specifically for homeowners, the MRCOOL DIY system includes an installation template for the wall-mounted air handler, making it easy to place holes for refrigerant lines, cables, and drain connections accurately. The simplified design eliminates guesswork and helps you complete installation faster with confidence.
Heat Pump Technology – Heating & Cooling
The MRCOOL DIY system is a true heat pump, providing both heating and cooling in one system. It transfers heat rather than generating it, delivering highly efficient comfort year-round. The system can heat in temperatures as low as -13°F and cool in temperatures up to 122°F, keeping your home comfortable in nearly any climate.
Variable-Speed DC Inverter Compressor
The MRCOOL DIY system uses advanced DC inverter technology to continuously adjust compressor speed based on your comfort needs. Instead of constantly turning on and off like traditional systems, it runs at the optimal level to maintain temperature while using less energy. This results in lower energy costs, quieter operation, and longer system life.
Smart Control with Wi-Fi & Voice Assistants
Take full control of your comfort from anywhere using the MRCOOL SmartHVAC app on iOS or Android. Adjust temperature, monitor usage, and set automated comfort schedules. The system also integrates with Amazon Alexa and Google Assistant for convenient voice control.
No-Vac Quick Connect® Line Sets
Installation is simple thanks to MRCOOL’s patented Quick Connect® fittings. The pre-charged line sets come sealed with refrigerant and connect using basic hand tools — no vacuum pump or specialized HVAC equipment required. Just align the fittings, tighten with a wrench, and your system is ready to go.
Protected DIYPro™ Communication Cable
The MRCOOL DIYPro™ communication cable connects the indoor air handler and outdoor condenser while protecting electrical wiring inside a durable protective conduit. This heavy-duty cable helps shield wiring from weather exposure and accidental damage during installation.
