The 36W58 is a genuine OEM Lennox scroll compressor built on the Copeland ZR34KA-PFV-130, rated at 34,400 BTUH on 208/230V, R-22 refrigerant, single-phase power. This compressor powers the refrigeration cycle in your Lennox residential or light-commercial unit, compressing and circulating refrigerant to move heat out of your space. Its scroll design offers quiet, efficient, and dependable single-phase operation.
Common failure symptoms: a unit that runs but won't cool, hard starting or tripped breakers, buzzing or grinding noises, a compressor that hums but fails to start (often a failed start component or internal fault), or frequent short-cycling. These signs usually mean an internal electrical short, seizure, or loss of compression.
Why OEM matters: The factory-engineered Lennox 36W58 matches your system's exact capacity, voltage, and R-22 refrigerant requirements. Choosing OEM preserves your equipment warranty, ensures correct oil and refrigerant compatibility, and restores rated cooling capacity and efficiency — avoiding the fitment and durability problems typical of generic aftermarket compressors.
