MRCOOL® 18,000 BTU DIY 5th Generation Wall Mount Air Handler 230V - DIY-18-HP-WMAH-230D25-O

The 5th Generation MRCOOL® DIY® 18K BTU Wall Mount Air Handler is a powerful and efficient solution for heating and cooling spaces up to 800 sq. ft. Designed with a true DIY installation in mind, this system eliminates the need for special tools or professional assistance, making setup fast, simple, and cost-effective. One of the standout features is the pre-charged 25-foot DIY® QuickConnect® line set, which comes pre-filled with R-454B refrigerant. This means there’s no need for vacuuming, cutting down on installation time and costs. Line sets are sold separately. Additionally, the included DIYPRO® cable removes the need for electrical conduit, providing added durability and protection against outdoor elements and wildlife. Controlling your system is effortless with multiple options to fit your lifestyle. Adjust settings using the wireless remote, the SmartHVAC app for Apple and Android devices, or hands-free voice commands through Amazon Alexa and Google Assistant. Engineered for long-lasting performance, the Gold Fin® Condenser in the outdoor unit offers superior corrosion resistance, especially beneficial in coastal environments. For added comfort, the Follow Me function on the remote allows the air handler to monitor and adjust airflow based on the remote’s location, ensuring even temperature control. Dry Mode helps maintain a comfortable indoor environment by reducing excess humidity and condensation buildup. Backed by industry-leading warranties—including a limited lifetime warranty, a 7-year compressor warranty, and a 5-year parts warranty—the 5th Generation MRCOOL® DIY® is built for reliability. Enjoy smart features, easy installation, and dependable year-round comfort with this innovative ductless mini-split system.
