Trane 5TXCD008AS3HC Cased Evaporator Coil 42000-60000 Btu 3.5-5.0 Ton Multi-position R-454B Split System Heat Pump

Product Description

The Trane 5TXCD008AS3HC is a cased, multi-position evaporator coil designed for residential split system air conditioning and heat pump applications. Rated at 42,000 to 60,000 BTU/h (3.5 to 5.0 tons), this coil features an aluminum plate-fin construction and a factory-installed non-bleed TXV for precise refrigerant metering. It is designed for use with R-454B refrigerant, with brazed refrigerant connections sized at 7/8 inch on the gas line and 3/8 inch on the liquid line. The D-cabinet configuration measures 24.5 inches wide. Licensed HVAC technicians typically install this coil as part of a new system installation or evaporator coil replacement in an existing split system.

This coil is suited for residential cooling and heat pump systems requiring 3.5 to 5.0 tons of capacity. Its multi-position, four-way airflow design allows installation in upflow, downflow, or horizontal configurations, making it adaptable to a range of air handler and furnace cabinet arrangements. The cased A-coil enclosure simplifies installation in ducted systems. It is intended for use in central forced-air residential systems where R-454B refrigerant is specified.

Key Features

• Factory-installed non-bleed TXV for accurate refrigerant flow control
• R-454B refrigerant compatible with brazed refrigerant connections
• Aluminum plate-fin coil construction for efficient heat transfer
• Multi-position four-way design supports upflow, downflow, and horizontal installation
• D-cabinet width of 24.5 inches fits standard residential air handler and furnace cabinets
• 3/4 inch NPT drain connection for condensate management

Compatibility

Designed as an OEM-style cased evaporator coil for residential split system air conditioners and heat pumps using R-454B refrigerant in the 3.5 to 5.0 ton capacity range. Gas line connection is 7/8 inch and liquid line connection is 3/8 inch. Verify system compatibility, refrigerant type, and cabinet dimensions before installation.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle refrigerants under applicable EPA Section 608 regulations. Disconnect and lock out all electrical power to the air handler or furnace before beginning coil installation or replacement. Refrigerant connections are brazed joints — use nitrogen purge procedures during brazing to protect internal components and prevent oxidation. Verify condensate drain slope and drainage path comply with local mechanical codes before startup.
