The Lennox 33M71 is a genuine OEM First Stage Condenser Coil engineered to deliver efficient heat transfer in Lennox two-stage cooling systems. This coil is responsible for releasing heat absorbed from indoor air into the outdoor environment, and it operates during the first stage of the cooling cycle for quieter, more energy-efficient operation. It is built to Lennox factory standards ensuring optimal refrigerant flow and thermal performance.

Signs of a failing or damaged condenser coil include refrigerant leaks, reduced cooling capacity, ice buildup on the system, or elevated energy bills. Replacing the coil with a genuine Lennox OEM part restores full system efficiency and ensures compatibility with your existing refrigerant and control systems.
