The genuine OEM Lennox 11B80 Copeland scroll compressor is the heart of your outdoor condensing unit, circulating and compressing refrigerant to move heat out of your home. Copeland scroll technology delivers quiet, efficient, and highly reliable operation, and this factory-specified unit is engineered to match the exact capacity, refrigerant, and electrical requirements of your Lennox system.

Common failure symptoms: When a scroll compressor fails, you may notice the outdoor unit no longer cooling, warm air from the vents, loud grinding or humming noises, frequent breaker trips, or the compressor tripping on its internal overload. A compressor that hums but won't start, or that is drawing high amperage, is often at the end of its service life.

Why OEM matters: Installing the correct OEM Lennox 11B80 compressor ensures proper refrigerant charge behavior, rated efficiency (SEER), and safe electrical draw. Aftermarket substitutions can create capacity mismatches, oil compatibility issues, and premature failures. Choosing the factory part protects your equipment warranty and restores your Lennox system to its designed performance. In stock and ships same day before 3PM CST.
