With a pre-charged 25-foot QuickConnect® line set filled with R-454B refrigerant, setup is simple and eliminates the need for vacuuming. The included DIYPRO® cable enhances durability, replacing traditional electrical conduit to protect against weather, animals, and yardwork damage. Controlling your comfort is seamless with multiple options, including the included remote, the SmartHVAC app for Apple and Android devices, or hands-free commands via Amazon Alexa and Google Assistant.

Equipped with a variety of features, this system enhances efficiency and comfort.
The Timer function helps manage energy use, while Auto mode maintains your desired temperature without constant adjustments. After a power outage, the system automatically resumes previous settings, and the anti-mildew function reduces condensation buildup in the air handler. Built for longevity, the 5th Generation MRCOOL® DIY® Mini Split offers an industry-leading warranty, including a limited lifetime warranty, plus a 7-year compressor and 5-year parts warranty. Combining advanced technology, user-friendly operation, and long-term reliability, this system is designed for hassle-free home comfort.
