Comfort control is simple and flexible. The system includes wireless remote control, app-based control through the MRCOOL Smart HVAC app, and compatibility with Amazon Alexa and Google Assistant. Features like Follow Me temperature sensing and Dry Mode dehumidification help fine-tune comfort throughout the year.

Engineered for durability, the outdoor condenser features Gold Fin® corrosion-resistant coating, making it suitable for harsh or coastal environments. Backed by strong manufacturer warranty coverage, the MRCOOL DIY® 36K system is built for long-term reliability and peace of mind.
