Midea DLFEHAA12XAJ Ductless Split Indoor Unit 12000 Btu/h

Product Description

The MIDEA DLFEHAA12XAJ is a cooling-only high wall indoor unit designed for ductless mini-split systems. Rated at 12,000 BTU/h and operating on 115 volts, it delivers a 16.8 SEER efficiency rating that meets the demands of residential and light-commercial applications. This unit mounts on an interior wall and connects to a compatible outdoor condensing unit via refrigerant lineset. It is installed by licensed HVAC technicians as part of a complete ductless split system, providing targeted zone cooling without the need for ductwork.

The DLFEHAA12XAJ is suited for single-zone cooling applications in residential spaces such as bedrooms, living areas, sunrooms, and add-on spaces where extending existing ductwork is impractical. Its 115-volt power requirement makes it compatible with standard residential electrical circuits, simplifying installation in retrofit and new-construction scenarios. This unit belongs to the Midea Performance Series, targeting applications where reliable, efficient zone cooling is the primary requirement.

Key Features

• 12,000 BTU/h cooling capacity for single-zone applications
• 16.8 SEER efficiency rating for reduced operating costs
• 115-volt operation compatible with standard residential circuits
• Cooling-only configuration — no heat pump function
• High wall mount design for unobtrusive installation and even air distribution
• Ductless operation eliminates the need for supply and return ductwork

Compatibility

Designed as an OEM indoor wall unit for Midea ductless split systems; must be paired with a compatible Midea outdoor condensing unit rated for cooling-only operation. Consult Midea system pairing documentation to confirm outdoor unit compatibility before installation.

Installation Notes

Installation must be performed by a licensed HVAC technician holding an EPA Section 608 certification for refrigerant handling. Shut off all electrical power to the circuit before mounting the indoor unit or connecting refrigerant lines. The lineset penetration through the exterior wall should be sealed to prevent air and moisture infiltration. Follow local mechanical and electrical codes, including NEC requirements for dedicated circuit sizing, when completing the installation.
