Trane 5TXCC007AS3HC Multi-position Cased Evaporator Coil 3.5 to 4 Ton 42000 to 48000 Btu R-454B

Product Description

The Trane 5TXCC007AS3HC is a multi-position cased evaporator coil designed for split-system cooling and heat pump applications using R-454B refrigerant, an A2L low-global-warming-potential refrigerant now standard in new residential HVAC equipment. The coil covers a capacity range of 42,000 to 48,000 BTU/h, serving 3.5 to 4 ton system configurations. Its four-way multi-poise design installs in upflow, downflow, or horizontal left or right orientations, giving installing technicians flexibility to match the coil to the air handler or furnace position without sourcing a dedicated-position unit. Cabinet width is 21 inches. The all-aluminum coil and fin construction provides natural corrosion resistance, reducing the risk of refrigerant leaks over the service life of the system. A factory-installed non-bleed TXV controls refrigerant metering on the indoor side.

This coil is suited for residential split-system installations paired with a compatible R-454B outdoor condensing unit or heat pump. The four-way poise configuration makes it a practical choice for replacement and new-construction installs where the mechanical room layout or furnace orientation may vary. The 21-inch cabinet fits standard residential duct openings for the 3.5 to 4 ton range. Licensed HVAC technicians handling R-454B systems should verify the outdoor unit, coil, and refrigerant line set are all rated and compatible for A2L refrigerant service before installation.

Key Features

• Four-way multi-poise design supports upflow, downflow, horizontal left, and horizontal right installations
• R-454B refrigerant service — A2L low-GWP refrigerant compatible with current efficiency and environmental regulations
• All-aluminum coil and fin construction for corrosion resistance and extended service life
• Factory-installed non-bleed TXV for precise refrigerant metering without field-installed components
• Capacity range of 42,000 to 48,000 BTU/h covers 3.5 to 4 ton system pairings
• 21-inch cabinet width fits standard residential air handler and furnace enclosures in this tonnage range

Compatibility

Designed for use with R-454B split-system condensing units and heat pumps rated for 3.5 to 4 ton capacity. Always verify outdoor unit compatibility, refrigerant line size ratings, and local jurisdiction requirements for A2L refrigerant installations before pairing components.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle A2L refrigerants, as R-454B has mildly flammable classification requirements that may trigger additional local code compliance steps beyond standard refrigerant handling procedures. Power down the air handler or furnace and shut off the disconnect at the outdoor unit before making any refrigerant or electrical connections. Braze refrigerant connections using appropriate techniques for aluminum coil systems and leak-check per standard industry practice before charging. All installation work must comply with applicable national, state, and local mechanical and electrical codes, including ANSI/NFPA 70 where electrical connections are involved.
