The genuine OEM Lennox 11X28 is a Copeland ZP25K6E-PFV-830 scroll compressor rated at 25,400 BTUH, running on 208/230V single-phase power with R-410A refrigerant. This compressor is the core component of your Lennox outdoor unit, compressing refrigerant vapor to move heat out of the home and sustain the cooling cycle. The proven ZP-series scroll design provides smooth, efficient, and durable performance.

Signs of a failing compressor include the outdoor unit running with little or no cooling, breakers tripping, loud grinding or knocking noises, hard starting or humming without turning over, and repeated shutdowns on thermal overload. These usually indicate worn scrolls, electrical winding failure, or a locked rotor.

Installing an OEM Lennox 11X28 ensures an exact match to the capacity, oil charge, electrical characteristics, and mounting your Lennox system requires. This protects rated efficiency, preserves warranty coverage, and delivers the long, reliable life that generic replacements often cannot guarantee.
