The Carrier 342813-75103 Replacement Kit is a critical OEM evaporator coil solution designed for high-performance residential and light commercial 4-way air systems. This A-coil replacement kit serves as the direct, factory-authorized successor to the legacy 340155-7024 and 326385-768 models. Engineered with high-grade aluminum, the coil is optimized for superior heat transfer and maximum airflow efficiency in 5-ton gas furnace and split-system heat pump configurations. Technicians should note that this kit is a drop-in replacement, preserving the original equipment's design specifications and agency listings. The 342813-75103 features a fully insulated cabinet and robust corrosion-resistant coating to withstand the rigors of continuous thermal cycling. Ensure the existing liquid and suction lines are compatible with the updated coil dimensions (20x28 inches) to maintain system subcooling and superheat integrity. This precision-engineered HVAC replacement part restores the system to its full latent and sensible cooling capacity.

Key Benefits:

• Factory Authorized Part: Ensures an exact fit and maintains the proprietary design specifications required for Carrier, Bryant, and Payne equipment.
• Enhanced Durability: Constructed with high-grade aluminum and a corrosion-resistant coating to prevent refrigerant leaks and extend the service life of the evaporator coil.
• Optimized Performance: Meets exact OEM airflow and pressure drop requirements, ensuring the furnace or air handler operates within its designed static pressure range.
• Streamlined Installation: Designed as a direct 340155-7024 replacement, reducing field labor time and ensuring seamless integration with existing ductwork.

Common Questions:

Is this a direct replacement for the 340155-7024 part?
Yes, the 342813-75103 is the official superseded part number for the 340155-7024. It is a direct "drop-in" replacement that maintains the same physical footprint and performance characteristics.

Which refrigerants are compatible with this A-coil?
This Carrier 342813-75103 is designed to meet modern industry standards; however, technicians must verify the specific metering device (TXV or piston) is compatible with the refrigerant type used in the existing condenser or heat pump.

Does this kit include the pressure switch or other hardware?
This kit typically includes the primary A-coil replacement and a cover. It is highly recommended to inspect all internal components during the swap to identify if supplemental hardware is required for the specific cabinet install.
