TRANE Evaporator Coil Assembly R-410A COL28450

TRANE Evaporator Coil Assembly R-410A COL28450

Part Number: COL28450
Refrigerant Type: R-410A
Category: Evaporator Coil Assembly | OEM Replacement Part

Product Overview

The COL28450 Evaporator Coil Assembly is a direct OEM replacement evaporator coil engineered to restore peak cooling and heat pump performance in Trane, American Standard, Ameristar, and Oxbox HVAC systems. Designed to meet or surpass original engineering specifications, this coil ensures reliable operation across residential and commercial HVAC, furnace, heat pump, and air handler applications. Whether you’re an HVAC technician or a homeowner managing a repair, the COL28450 delivers the dependable performance your system demands.

Key Features

OEM-Grade Engineering
The COL28450 is manufactured to match the exact design standards of the original factory part — ensuring a precise fit, proper refrigerant flow, and no compromises in system efficiency.

R-410A Refrigerant Compatible
The HVAC industry is transitioning toward R-454B, but R-410A systems remain widely in use, making the COL28450 an essential replacement part for the existing installed base of equipment.

Plug-and-Play Installation
Built for plug-and-play compatibility, this coil reduces downtime while ensuring Trane systems operate safely and efficiently throughout the year.

Durable, High-Quality Construction
All-aluminum coil design is engineered to withstand years of corrosion, remaining intact and functional even after 500 hours of sea salt spray exposure — unlike copper tubing used by many competitors.

Wide Application Range
Suitable for gas and electric furnaces, heat pumps, air conditioners, blowers, motors, control boards, heat exchangers, burners, valves, and a broad range of HVAC components.

Benefits

• Restore System Efficiency — A worn or leaking evaporator coil causes your system to work harder and consume more energy. Replacing it with the COL28450 brings your system back to peak SEER performance.
• Prevent Costly Breakdowns — Genuine OEM-spec parts reduce the risk of refrigerant leaks, pressure imbalances, and compressor damage caused by poorly fitted aftermarket coils.
• Lower Long-Term Operating Costs — Proper heat exchange means your compressor runs fewer cycles, extending the life of your entire HVAC system.
• Year-Round Reliability — Engineered for both cooling and heat pump applications, the COL28450 performs in summer and winter conditions alike.

Compatibility

The COL28450 Evaporator Coil Assembly is confirmed for use with the following air handler model numbers:

• J4AH4E36A1B00AA
• J4AH4P36A1B00AA
• M4AH4E37B1B00AA
• M4AH4P36B1B00AA
• M4AH4036A1000AA

Also cross-compatible with select American Standard, Ameristar, and Oxbox systems using equivalent air handler configurations. Always verify your specific model number before ordering. If you’re unsure of compatibility, consult your system’s data plate or contact a licensed HVAC technician.
