Trane 5TXCA002AS3HC Cased Evaporator Coil 30000-36000 Btu 2.5-3 Ton Multi-position R-454B

Product Description

The Trane 5TXCA002AS3HC is a multi-position cased evaporator coil rated at 30,000 to 36,000 BTU/h (2.5 to 3 tons) for use with R-454B refrigerant in residential split-system air conditioners and heat pumps. The all-aluminum plate-fin coil construction delivers strong corrosion resistance, and the factory-installed non-bleed TXV provides accurate refrigerant metering without additional field components. The 14.5-inch cabinet width fits standard residential air handler and furnace openings. Licensed HVAC technicians install and braze this coil as part of a matched split system.

This coil is designed for residential split-system applications pairing with a compatible outdoor condensing unit or heat pump. Its multi-position design supports upflow, downflow, and horizontal installation orientations, making it suitable for a range of duct configurations and equipment closet layouts. It is compatible with variable-speed air handler and furnace platforms. The coil is part of the 5TXC series, which covers aluminum premium multi-poise cooling and heat pump coil configurations.

Key Features

• All-aluminum plate-fin coil construction for corrosion and rust resistance
• Factory-installed non-bleed TXV for accurate refrigerant metering
• R-454B (A2L) refrigerant compatible
• Multi-position installation: upflow, downflow, or horizontal
• Two-piece, non-corrosive inner coil panels removable for interior fin cleaning
• Copper-brazed refrigerant connections for reliable field joining
• Designed for compatibility with variable-speed systems

Compatibility

Designed as an OEM-style replacement or new-installation evaporator coil for residential split-system air conditioners and heat pumps using R-454B refrigerant with a 14.5-inch cabinet width.

Installation Notes

Installation must be performed by an EPA 608-certified HVAC technician. Shut off all power to the air handler or furnace and close the refrigerant service valves on the outdoor unit before beginning coil replacement or installation. Refrigerant connections are brazed; use nitrogen purge during brazing to prevent oxidation inside the tubing. R-454B is an A2L mildly flammable refrigerant — follow current ASHRAE 15 and local code requirements for safe handling and ventilation during service.
