With Quick Connect lines pre-charged with eco-friendly R-410A refrigerant, there's no need for an HVAC technician. Simple video instructions guide you through the installation process, making it a breeze. The system cools during the summer, heats in the winter, and dehumidifies during wet seasons.
Easily monitor and control the temperature in each room using the easy-to-read digital display or the MRCOOL Smart Controller mobile app. If any issues arise, the display on each indoor air handler unit shows troubleshooting codes and alerts. Enjoy wireless operation with the included remote or the mobile app, compatible with Apple and Android devices. Seamlessly integrate the system with Amazon Alexa or Google Home for voice control.
The air handlers provide directional control of heated or cooled air, ensuring even distribution for maximum comfort. In emergency situations, the MRCOOL DIY System can be set to manual mode for testing or maintenance tasks. The auto mode adjusts heat or air conditioning based on your desired temperature, and a drying function controls air temperature while dehumidifying.
Save energy and money with sleep mode, which operates in an 8-hour window once activated. Customize your system with the timer function to limit energy usage and reduce utility bills. If your system runs low on refrigerant, an alert appears on the display, indicating a potential leak.
For a quiet environment, mute each indoor unit to silence alerts and turn off the LED display. In case of a power outage, the system automatically shuts off and restarts with the same settings once power returns. The user manual provides an index for troubleshooting codes and automatic air filter cleaning alerts. Keep indoor units clean with a dry or damp cloth.
Invest with confidence as the system comes with a 7-year compressor warranty (plus a limited lifetime compressor warranty) and a 5-year parts manufacturer warranty.
