Introducing the new 5th Generation MRCOOL® DIY® 18K BTU 22.5 SEER Ductless Heat Pump Single Zone Mini Split Condenser, a game-changer for home climate control. Designed for straightforward installation, it requires no specialized tools or professional help, making it an excellent choice for spaces ranging from 500-750 sq. ft. The system includes a pre-charged 25-foot QuickConnect® line set filled with R-454B refrigerant, streamlining installation by eliminating the need for vacuuming. The DIYPRO® cable adds extra protection against weather, animals, and yardwork damage, replacing the need for traditional electrical conduit.

Managing your home's temperature has never been easier. You can adjust settings using the included remote, the SmartHVAC app for Apple and Android devices, or voice commands via Amazon Alexa and Google Assistant. The Gold Fin Condenser enhances durability, providing excellent corrosion resistance for coastal environments. Designed for efficiency and comfort, this system offers multiple features. The Timer function helps control energy use, while Auto mode maintains your preferred temperature without manual adjustments. After a power outage, the unit automatically restores previous settings, and the anti-mildew function prevents excess moisture buildup inside the air handler. 

Built for long-term reliability, the 5th Generation MRCOOL® DIY® Mini Split comes with an industry-leading warranty, featuring a limited lifetime warranty, plus 7 years on the compressor and 5 years on parts.
