Carrier 342856-75103 Coil Kit
The Carrier 342856-75103 Coil Kit is a direct OEM evaporator replacement designed for precise fitment in specific Carrier, Bryant, and Payne air handlers and modular blowers. Engineered for high-efficiency thermal transfer, this aluminum fin evaporator coil utilizes precise rifled copper tubing to maximize refrigerant turbulence and heat exchange surface area. As a critical component in the secondary heat exchange process, the 342856-75103 coil ensures the system maintains specified static pressure and airflow CFM requirements. Replacing a leaking or fouled coil with this genuine Carrier replacement part restores system subcooling and superheat levels to factory parameters, preventing compressor slugging and premature cycling. This kit includes the necessary components for a standard field installation, including required gaskets and hardware. For technicians performing a HVAC evaporator coil replacement, this heavy-gauge assembly provides the structural integrity needed to withstand high-velocity airflow and condensate management without bypass or carryover issues.
- Corrosion Resistance: High-grade aluminum fin stock resists formicary corrosion and environmental degradation in high-moisture environments.
- Optimized Heat Transfer: Rifled tubing enhances refrigerant flow dynamics for maximum cooling capacity and energy efficiency.
- OEM Precision: Direct drop-in compatibility eliminates the need for field modifications to the plenum or refrigerant lines.
- Reliable Drainage: Designed with specific slope requirements to ensure proper condensate runoff and prevent pan overflow.
Common Questions
Is this coil compatible with R-410A systems?
Yes, the Carrier 342856-75103 is engineered for high-pressure R-410A applications and is compatible with standard thermal expansion valves (TXV) used in modern residential splits.
What causes a coil failure in these units?
Standard failure modes include pinhole leaks due to formicary corrosion or restricted heat transfer caused by debris accumulation between the fins. Using this HVAC coil kit ensures the replacement meets original manufacturer specifications.
Does this kit include the TXV?
Technicians should verify the specific unit tonnage; while the kit provides the coil and housing components, the expansion valve is often sourced separately based on the specific outdoor unit capacity.
