The Carrier 342813-75101 Coil Kit is a factory-authorized aluminum evaporator coil designed for high-efficiency heat transfer in residential and light commercial split systems. Built to replace aging or leaking copper and tin-plated units, this replacement A-coil kit provides a direct fit for 410A refrigerant applications. It is the designated engineering replacement for legacy part numbers 326385-770, 326385-781, and 340155-7031, ensuring seamless integration with existing Carrier, Bryant, and Payne air handlers and cased furnace coils. This kit includes the necessary components for a standard field swap, featuring a reliable TXV (Thermostatic Expansion Valve) rated for 3-ton applications and 14 fins per inch (FPI) to optimize airflow and dehumidification performance. For technicians performing a coil leak repair, the all-aluminum construction offers superior resistance to formicary corrosion compared to older copper models, maintaining system static pressure and energy integrity.

• OEM Compatibility: Engineered as a direct drop-in for Carrier 340155-7031 and 326385 series coils.
• Aluminum Construction: Utilizes advanced aluminum fin and tube design to eliminate corrosive pitting and extend service life.
• Integrated TXV: Ships with a factory-calibrated expansion valve compatible with R-410A refrigerant.
• High-Efficiency Transfer: Optimized fin density provides consistent cooling performance and moisture removal.

Common Questions

Is this a direct replacement for tin-plated coils?
Yes, the 342813-75101 is the official replacement for legacy tin-plated and copper evaporator coils, specifically addressing common leak points in older air handlers.

Does this kit include the expansion valve?
This kit typically includes the evaporator coil assembly with the TXV already mounted or supplied for field installation to ensure proper superheat control.

What refrigerant is this coil rated for?
This coil is designed and pressure-tested for use with R-410A systems and should not be used with R-22 without proper component verification.
