Key Features & Benefits

✅ High-Capacity Performance for Large Spaces
With 36,000 BTU (3-Ton) output, this air handler efficiently manages climate control in areas where standard units fall short. Ideal for great rooms, master suites, converted garages, and open-concept living areas.

✅ Designed for DIY QuickConnect® Compatibility
This indoor unit is engineered specifically for use with MRCOOL’s QuickConnect® pre-charged line sets. When paired with a compatible 36K BTU outdoor condenser, installation becomes tool-simple with no vacuum pump or refrigerant handling required.

✅ Ready for DIYPRO® Electrical Integration
Features built-in connections for the MRCOOL DIYPRO® cable (sold separately with condenser), which combines power and communication wiring into one durable, weather-resistant line—eliminating the need for separate electrical conduit.

✅ Smart, Multi-Platform Control
Operate your comfort system your way. Use the included wireless remote, adjust settings from anywhere via the SmartHVAC app (iOS/Android), or use voice commands with Amazon Alexa and Google Assistant.

✅ Follow Me Personalized Comfort
The wireless remote acts as a smart comfort sensor. When enabled, the air handler detects the remote’s location and directs airflow to maintain your preferred temperature exactly where you are in the room.

✅ Dry Mode for Humidity Control
More than just heating and cooling—this specialized function operates as a quiet dehumidifier, removing excess moisture to enhance comfort on humid days and help improve indoor air quality.
