Rheem-Ruud RCBA-3765T Evaporator Coil W/Drain Pan

Thermostatic expansion valves are an integral part of your refrigeration unit. They are responsible for ensuring the right dosage of refrigerant is entering the cooling coil to ensure maximum efficiency in the air conditioning of the system.    These special expansion valves come with a temperature sensor that is mounted at the end of the evaporator coil. They incorporate signals from this sensor to maintain the required temperature of the HVAC system. The thermostatic expansion valve works like a precision device that can regulate the measurements of the liquid refrigerant that flows into the evaporator of your system. This regulation in the flow of the refrigerant is essential to prevent the reverse flow of the refrigerant into the compressor of your system.    Through this mechanism, the thermostatic expansion valve successfully separates the high and low pressure sides of the refrigeration/air conditioning system. The liquid refrigerant enters the expansion ...

It's recommended to replace both the evaporator coil and the drain pan together to ensure compatibility and efficient condensate management.

Cleaning frequency depends on usage, but generally, it's advisable to clean them annually to maintain efficient performance and prevent mold growth.

Inspect the evaporator coil regularly for dust buildup and clean it to maintain efficient heat transfer. Check the drain pan and drain line for clogs to prevent water overflow and leaks. Ensure refrigerant connections remain tight and free from corrosion. Schedule professional servicing to verify airflow, coil condition, and proper drainage.

• Reduced cooling efficiency.
• Leaks or corrosion in the coil.
• Clogged drain pan or line.
• Uneven airflow or frost buildup.
