Why Use an Accumulator?
Accumulators are essential refrigeration components installed on the suction line between the evaporator and the compressor. They collect any unevaporated liquid refrigerant and oil, preventing it from entering the compressor and causing mechanical damage. Using a genuine Lennox replacement accumulator ensures your system operates as designed, preserving warranty compliance and system integrity.
