Designed for effortless installation, this system requires no special tools or prior experience and efficiently heats or cools spaces up to 750 sq. ft. The pre-charged 25-foot DIY® QuickConnect® line set, filled with R-454B refrigerant, eliminates the need for vacuuming, making installation faster, easier, and more cost-effective. Plus, the DIYPRO® cable eliminates the need for electrical conduit, ensuring greater durability against outdoor elements and wildlife.

Take control of your comfort with multiple convenient options, including a wireless remote, the SmartHVAC app for Apple and Android devices, and hands-free voice commands via Amazon Alexa and Google Assistant. The Gold Fin® Condenser offers exceptional corrosion resistance, making it ideal for coastal climates and ensuring long-lasting performance even in harsh weather conditions.

Designed with both efficiency and comfort in mind, the system features the Follow Me function, which adjusts airflow based on the remote’s location to maintain even temperatures throughout the room. Additionally, Dry Mode acts as a built-in dehumidifier, reducing excess moisture for a healthier indoor environment.
