The Lennox 40W58 is a genuine OEM Interlink SQA038KAA scroll compressor rated at 37,000 BTUH for 208/230V single-phase systems using R-22 refrigerant. As the central component of your outdoor condensing unit, this compressor compresses and circulates refrigerant to drive the heat-transfer cycle that cools your space. Its scroll design offers quieter, more efficient, and more reliable operation than older reciprocating models.

Common failure symptoms: Indicators of a failing compressor include a unit that hums but won't start, repeated breaker trips, insufficient or no cooling while running, loud vibration or knocking, and overheating during operation. These usually stem from worn scrolls, failed windings, or a seized internal component.

Why OEM matters: The 40W58 is manufactured to precise Lennox specifications for capacity, oil compatibility, and electrical load on R-22 systems. Legacy R-22 equipment requires a compressor built for the correct refrigerant and pressure range, so choosing the factory-authorized OEM part ensures proper fit, sustained efficiency, and dependable long-term performance.
