Trane 5TXCD010AS3HC Cased Evaporator Coil 42000-60000 Btu 3.5-5.0 Ton Multiposition 24.5 Inch Cabinet R-454B

Product Description

The Trane 5TXCD010AS3HC is a cased, multiposition evaporator coil rated for 42,000 to 60,000 BTU/h (3.5 to 5.0 tons) for use in residential split-system air conditioners and heat pumps. The coil and fin assembly are constructed from aluminum, delivering inherent corrosion resistance and long service life. A factory-installed non-bleed TXV is included, eliminating the need for a field-supplied metering device. The unit is designed for R-454B refrigerant and features brazed refrigerant connections. Licensed HVAC technicians install this coil as the indoor half of a split system, pairing it with a compatible outdoor condensing unit or heat pump.

This coil is intended for residential split-system installations in upflow, downflow, or horizontal configurations. The 24.5-inch wide D-cabinet fits standard air handler and furnace platforms that accept that cabinet width. It is rated across a capacity range of 3.5 to 5.0 tons, making it suitable for single-family homes and light-duty residential applications where R-454B system compliance is required. Also sold under the American Standard brand as model 5TXCD010AS3HCA.

Compatibility

Designed for use in residential split-system air conditioning and heat pump applications requiring a 24.5-inch wide cased evaporator coil rated for R-454B refrigerant. Also offered under the American Standard brand as part number 5TXCD010AS3HCA.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle R-454B refrigerant in accordance with applicable EPA and local regulations. Power down the air handler or furnace and shut off the disconnect before beginning any coil work. Refrigerant line connections are brazed — use dry nitrogen purge during brazing to prevent oxide contamination inside the copper tubing. Verify drain pan and condensate line routing before startup, and confirm system refrigerant charge per the outdoor unit manufacturer specifications after installation.
