Smart app control plus voice assistants. Use MRCOOL’s app or your Amazon Alexa / Google Home for hands‑free comfort control, scheduling, and energy monitoring.
Future‑ready refrigerant and controls.

Independent installer outlets note the 5th‑gen upgrade focuses on eco‑friendliness, higher efficiency, and enhanced controls.
