These sleek, ENERGY STAR® Certified indoor units are specifically designed for compatibility with the 5th Gen MRCOOL Multi-Zone DIY outdoor condensers and Quick Connect line sets using R-454B refrigerant.

Perfect for homeowners who want professional performance with DIY simplicity, each unit offers ultra-quiet operation, modern styling, and unmatched energy efficiency—backed by one of the easiest installation processes in the industry.

Product Highlights:

ENERGY STAR® Certified for maximum energy savings and efficiency
True DIY Installation – no special tools or HVAC license required
Available in 9k, 12k, 18k, 24k, and 36k BTU capacities to match any room size
Includes 25 ft. control wire (used with matching 25 ft. line set)
Quick Connect compatible with MRCOOL pre-charged R-454B line sets (sold separately)

📋 Installation Note:

Every wall-mounted air handler comes with a 25-foot control wire included in the box. If your installation uses a longer line set (35, 50, or 75 feet), you will need to swap out the included 25 ft wire for the longer control wire that comes with your selected line set. This ensures reliable communication between the indoor and outdoor units without voltage drop or wiring issues.

Each air handler requires a dedicated line set and control wire. Make sure your selected components match the distance from the air handler to the condenser for best results.

⚠️ Note: This listing is for indoor wall-mounted air handlers only. Please pair with a compatible 5th Gen MRCOOL Multi-Zone outdoor condenser and DIY line sets to complete your system.
