The MRCOOL DIY 5th Gen 12K BTU Ductless Mini Split Heat Pump makes heating and cooling simple with true do-it-yourself installation. Perfect for rooms up to 550 square feet, this system includes a pre-charged QuickConnect line set filled with R-454B refrigerant, so no vacuuming or special tools are required. The durable DIYPRO cable removes the need for electrical conduit while protecting against outdoor damage, making setup faster and more secure. Control is effortless using the wireless remote, the SmartHVAC app, or hands-free voice commands through Alexa and Google Assistant. Built with a corrosion-resistant Gold Fin condenser, it’s designed to last even in coastal environments. Comfort is personalized with Follow Me technology, which adjusts airflow based on the remote’s location, while Dry Mode reduces humidity for a healthier indoor space. Backed by a limited lifetime warranty, seven years of compressor protection, and five years on parts, this energy-efficient system delivers lasting performance, smart control, and dependable year-round comfort.
