The MRCOOL DIY 5th Gen Multi-Zone 2-Zone 18,000 BTU Ductless Mini-Split offers a flexible and energy-efficient solution for heating and cooling your home. Designed with DIY installation in mind, this system eliminates the need for expensive professional HVAC services. Pre-charged Quick Connect® line sets allow homeowners to connect the indoor and outdoor units with ease, while eco-friendly R-454B refrigerant ensures sustainability and efficiency.
Each indoor air handler provides 9,000 BTU of heating and cooling, covering approximately 400 square feet per room. As a heat pump system, it can reverse operation to pull heat from the outdoors, providing reliable warmth during cooler months. With a 24 SEER2 rating and advanced DC inverter technology, this system delivers high efficiency, helping you save on energy costs while maintaining optimal comfort.
The MRCOOL DIY Multi-Zone system supports up to three indoor units, allowing customizable comfort for multiple rooms. It also features smart integration through the MRCOOL Smart HVAC app, compatible with both Amazon Alexa and Google Home. Control your system remotely, set schedules, and monitor performance all from your smartphone, bringing convenience and total control to your fingertips.
Backed by a 7-year compressor warranty, a 5-year parts warranty, and a Limited Lifetime Replacement warranty with MRCOOL Care enrollment, this system ensures long-term peace of mind. The DIY Series remains the #1 best-selling mini split in America, offering both affordability and superior performance for any home.
