The genuine OEM Lennox 19H70 tandem compressor assembly is a 208/230V, 3-phase unit built for commercial and light-commercial Lennox equipment. Two compressors work in tandem to deliver staged capacity, allowing the system to trim output to match load, reduce energy use, and hold precise temperatures. As the refrigerant pump at the core of the cooling circuit, this assembly drives the heat-transfer process that keeps your space conditioned.

Common failure symptoms include loss of cooling, tripped breakers, loud mechanical noise, a compressor that hums but fails to start, rapid short cycling, or high amperage draw. Overheating and failed internal windings on a 3-phase compressor generally call for complete replacement.

Why OEM matters: This assembly is matched to your unit's tonnage, refrigerant charge, and 208/230V 3-phase electrical supply. Installing the factory-specified 19H70 ensures correct voltage compatibility, proper fit, and rated performance while keeping your Lennox warranty intact. Confirm your unit's voltage and phase before ordering, and have a licensed HVAC technician recover refrigerant, evacuate the system, and verify phasing and charge during installation.
