OEM Lennox Copeland Scroll Compressor — 11C35

The genuine OEM Lennox 11C35 is a Copeland scroll compressor that serves as the core of your Lennox cooling or heat pump system. It pressurizes and circulates refrigerant between the indoor and outdoor coils to move heat out of your home. As a factory-specified Copeland scroll unit, the 11C35 provides the precise refrigerant capacity and smooth, efficient operation that your Lennox system depends on.

Common failure symptoms: watch for a unit that hums or buzzes but won't start, a system that runs continuously without cooling, tripped breakers on start-up, loud metallic or grinding noises, or short-cycling caused by the compressor overheating and tripping its overload. A grounded or shorted winding will stop the compressor from energizing entirely.

Why OEM matters: Lennox equipment is factory-charged for a specific compressor displacement and electrical rating. Using the genuine 11C35 guarantees correct refrigerant flow, preserves system warranty coverage, and prevents the efficiency loss and early failures often seen with generic aftermarket compressors. This direct-fit OEM replacement restores your Lennox system to its rated performance.
