Trane 5TXCC005AS3HC Cased Evaporator Coil 36000-42000 Btu/h 3.0-3.5 Ton R-454B Multi-position

Product Description

The Trane 5TXCC005AS3HC is a cased aluminum A-coil evaporator designed for residential split-system air conditioners and heat pumps. Rated at 36,000 to 42,000 BTU/h (3.0 to 3.5 ton), it handles the evaporator side of the refrigerant circuit, absorbing heat from indoor air and delivering it to the outdoor unit. The coil uses R-454B refrigerant and ships with a factory-installed non-bleed TXV for precise refrigerant metering. Cabinet width is 21.0 inches, and the unit supports upflow, downflow, and horizontal installations. Licensed HVAC technicians install this coil as part of a new system build or a matched-system replacement.

This coil is suited for residential split-system cooling and heat pump applications. Its multi-position design gives installers flexibility in air handler orientation without requiring a separate coil SKU for each application. The plate-fin aluminum coil construction supports efficient heat transfer across the rated capacity range. Refrigerant connections are brazed, with a 7/8-inch gas line and 3/8-inch liquid line, matching common residential line set sizing for 3.0 to 3.5 ton systems. Drain connections use a 3/4-inch NPT fitting.

Key Features

• Rated capacity of 36,000 to 42,000 BTU/h (3.0 to 3.5 ton) for residential split systems
• R-454B refrigerant compatibility — meets current low-GWP refrigerant requirements
• Factory-installed non-bleed TXV for accurate refrigerant metering without field adjustment
• Aluminum plate-fin coil construction for corrosion resistance and efficient heat transfer
• Multi-position cabinet supports upflow, downflow, and horizontal installation orientations
• 21.0-inch cabinet width with brazed refrigerant connections — 7/8-inch gas, 3/8-inch liquid

Compatibility

Designed for use in residential split-system air conditioning and heat pump configurations requiring a 3.0 to 3.5 ton cased evaporator coil with R-454B refrigerant. Consult Trane system match tables to confirm pairing with a specific outdoor unit or air handler before installation.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle A2L refrigerants, including R-454B. Shut down and lock out the system before opening any refrigerant circuit. Refrigerant connections are brazed — follow applicable mechanical codes and use proper PPE including cut-resistant gloves and safety glasses when working with coil surfaces and refrigerant lines. Minimize refrigerant line length and verify drain line slope and trap depth per the manufacturer installation manual before startup.
