Full 1:1 Direct Replacement Heat Pump Evaporator Coils for Global HVAC Retrofit Market

Designed for global HVAC contractors, retail chains, property management firms and aftermarket distributors, the 1:1 drop-in coils remove the need for cabinet cutting, duct rework or structural adjustment during coil replacement, drastically shortening on-site service hours and lowering overall retrofit labor costs.

All coils are custom-produced according to the actual size of the failed old coil or customer-provided drawings, achieving full physical and structural consistency with the original unit.

1:1 duplication covers every critical parameter:

- Overall dimension: height, width, depth, coil bending angle

- Mounting position: bracket hole spacing, fixing height, assembly reserved space

- Pipeline structure: tube diameter, inlet/outlet position, circuit layout, bending path

- Airflow structure: fin height, fin spacing, air inlet direction

- Drainage structure: condensate slope, drain pan matching size

This ensures the new coil can directly replace the old one without any cabinet cutting, frame modification or on-site structural adjustment.

The 1:1 custom replacement service supports all mainstream coil shapes for heat pump and HVAC systems:

- A-coil: Standard air handler replacement for residential split heat pumps

- G-coil: Precision replacement for square ceiling cassette units, perfect for retail and commercial spaces

- U-coil: Compact high-capacity replacement for vertical concealed units and modular heat pumps

- O-coil: 360° full-wrap high-efficiency coil duplication for commercial high-end heat pump systems
