Why This High-Capacity Air Handler Is Perfect for Your Space

✅ Powerful Performance for Large Areas: With 24,000 BTU (2-Ton) capacity, this indoor unit efficiently manages climate control in spaces where standard units fall short—ideal for great rooms, master suites, converted garages, and open floor plans.

✅ Designed for DIY QuickConnect® Systems: This air handler is engineered specifically for use with MRCOOL's QuickConnect® pre-charged line sets. When paired with a compatible outdoor condenser, installation becomes truly tool-simple with no vacuum pump or refrigerant expertise required.

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

✅ Multiple Smart Control Options: Operate your comfort system your way. Use the included wireless remote, control settings from anywhere with the SmartHVAC app (iOS/Android), or use convenient voice commands with Amazon Alexa and Google Assistant.

Advanced Comfort Features

• Follow Me Technology: The wireless remote acts as a smart comfort sensor. When enabled, the air handler detects the remote's location and directs airflow to maintain personalized 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 to remove excess moisture from the air, enhancing comfort on humid days and helping prevent mold and mildew.

• Multi-Directional Airflow: Engineered with adjustable louvers to distribute high-volume airflow quietly and evenly throughout your large space, preventing hot or cold spots.

Compatibility & Warranty

• Pairs with 24K BTU Condensers: Designed to work seamlessly with MRCOOL DIY 24K BTU Outdoor Condensers (5th Generation recommended), particularly those featuring Gold Fin® anti-corrosion technology for durability in coastal or harsh environments.

• Protected by MRCOOL Warranty: This indoor unit is covered by a 5-year parts warranty and is part of a system backed by MRCOOL's comprehensive protection, including a 7-year compressor warranty and limited lifetime warranty on the outdoor coil when used with compatible components.
