The Lennox 15W10 is a genuine OEM Copeland ZP34K5E-PFV-830 scroll compressor delivering 34,500 BTUH (approximately 3 tons) on 208/230V single-phase power for R-410A systems. This compressor is the workhorse of your Lennox condensing unit, compressing and circulating refrigerant to carry heat out of your home. It is manufactured to the precise capacity, voltage, and connection specifications of compatible Lennox air conditioners and heat pumps.

Common failure symptoms: no cooling with the outdoor fan still running, a humming unit that will not start, breakers tripping on start-up, short-cycling, loud grinding or knocking, excessive vibration, and internal overload trips from overheating. A grounded or seized compressor will prevent the system from cooling.

Why OEM matters: the factory-matched 15W10 guarantees the correct scroll displacement, motor windings, and built-in protection your Lennox R-410A equipment was designed to use. Aftermarket or mismatched compressors can cause capacity shortfalls, efficiency loss, oil-management problems, and premature breakdown. OEM delivers exact fit, rated efficiency, and long-term reliability.
