OEM Lennox Scroll Compressor 21,500 BTUH R-22 — 32W18

The Lennox 32W18 is a genuine OEM Interlink SQA022KAA scroll compressor rated at 21,500 BTUH, built for 208/230V single-phase operation with R-22 refrigerant. As the core of your Lennox condensing unit, this compressor pressurizes and circulates refrigerant to drive the cooling cycle. Its scroll design offers smooth, efficient, low-vibration performance and is an ideal like-for-like replacement for keeping legacy R-22 Lennox systems in reliable service.

Common failure symptoms: A worn or failed compressor commonly shows up as a system that won't cool, a unit that hums or clicks but doesn't start, tripped breakers, hard starting, loud rattling or grinding noises, and overheating that trips the internal overload. Loss of compression, shorted windings, and a locked rotor are typical end-of-life conditions.

Why OEM matters: The 32W18 is engineered to Lennox factory specifications for single-phase electrical characteristics, displacement, and R-22 compatibility. Because R-22 equipment can't simply be re-sourced with modern refrigerant models, a genuine OEM replacement is the most dependable way to restore rated capacity and extend the life of your installed system while preserving warranty. Verify voltage, phase, and refrigerant on your nameplate before ordering.
