Trane 5TXCB003AS3HCA – 18-30,000 BTU 1.5–2.5 Ton Aluminum Cased Upflow / Downflow / Horizontal Evaporator Coil

Deliver reliable indoor cooling and heat pump performance with the Trane 5TXCB003AS3HCA, a premium aluminum evaporator coil designed for residential split system HVAC applications. As part of Trane’s 5TXC Series Comfort™ coil platform, this cased indoor coil features durable aluminum plate-fin construction, a factory-installed non-bleed thermostatic expansion valve (TXV), and flexible multi-position installation capability engineered to support efficient refrigerant control and dependable HVAC system operation.

1.5–2.5 Ton Cooling Capacity Platform
The 5TXCB003AS3HCA coil is designed to support nominal cooling capacities ranging from approximately 1.5 to 2.5 tons when paired with compatible Trane split system air conditioners or heat pumps. The coil utilizes a three-row plate-fin configuration with 14 fins per inch and approximately 3.5 square feet of face area, helping improve heat transfer efficiency and airflow performance in residential HVAC systems.

Aluminum Plate-Fin Coil Construction
The evaporator coil utilizes 3/8-inch seamless aluminum tubing mechanically bonded to aluminum plate fins to promote efficient heat transfer and long-term corrosion resistance. This all-aluminum design helps maintain consistent refrigerant flow while improving durability and system reliability in residential cooling and heat pump applications.

Factory-Installed Non-Bleed TXV Refrigerant Control
The 5TXCB003AS3HCA features a factory-installed non-bleed thermostatic expansion valve (TXV) designed to precisely regulate refrigerant flow during cooling and heat pump operation. This advanced refrigerant metering device helps improve system efficiency, maintain consistent evaporator temperatures, and optimize HVAC performance under varying load conditions.

Compatibility with R-454B Refrigerant Systems
The coil is designed for compatibility with modern R-454B refrigerant systems and includes brazed refrigerant connections with a 3/4-inch gas line and 3/8-inch liquid line. This configuration supports use with next-generation Trane outdoor units designed for improved energy efficiency and reduced environmental impact.

Multi-Position Installation Flexibility
The 5TXC Series cabinet supports installation in upflow, downflow, or horizontal configurations, allowing the coil to be integrated into a variety of residential HVAC system layouts. This multi-position installation capability provides flexibility when pairing the coil with furnaces or air handlers in closets, basements, attics, or mechanical spaces.

Integrated Drain Pan Design for Condensate Management
The coil assembly includes a vertical drain pan with primary and secondary drain connections for vertical installations as well as a horizontal drain pan with primary and secondary drain connections for horizontal configurations. This dual drain pan system helps ensure reliable condensate management and protects surrounding HVAC components during cooling operation.

Service-Friendly Cabinet with Coil Access
The cabinet design includes removable front and interior access panels that allow technicians to easily access the evaporator coil entering air surface for inspection and cleaning. This service-friendly design simplifies routine maintenance and helps maintain optimal system performance over time.

Compact Cased Coil Cabinet Design
The 5TXCB003AS3HCA features an uncrated cabinet size of approximately 17.5 inches high, 17.5 inches wide, and 21.5 inches deep, allowing installation in tight residential mechanical spaces while maintaining proper airflow capacity for efficient split system HVAC performance.

Engineered for Efficient Split System HVAC Performance
Ideal for residential cooling and heat pump systems, the Trane 5TXCB003AS3HCA evaporator coil combines efficient refrigerant control, durable aluminum coil construction, and flexible installation capability in a compact cased coil platform designed to support reliable indoor comfort and long-term HVAC system performance.
