OEM Lennox Reciprocating Compressor 34,500 BTUH R-22 — 14K48

The Lennox 14K48 is a genuine OEM Tecumseh AVB5535EXH reciprocating compressor rated at 34,500 BTUH, built for 575V three-phase power with R-22 refrigerant. Reciprocating compressors use a piston-and-cylinder design to compress refrigerant vapor, making them a proven, serviceable choice for legacy Lennox commercial cooling systems. This high-voltage three-phase unit is ideal for restoring older R-22 equipment where a like-for-like replacement is required to keep the system operating.

Common failure symptoms: Typical signs of compressor failure include no cooling despite the fan running, loud knocking or clanking from the piston assembly, hard starting or failure to start, tripped breakers, high or low discharge pressures, and overheating that trips the internal or external overload. Valve wear, blown gaskets, and worn bearings are common in reciprocating units.

Why OEM matters: Sourcing the genuine 14K48 ensures the correct 575V three-phase electrical match, proper R-22 compatibility, and factory-rated capacity for your Lennox system. With R-22 equipment, an exact OEM replacement is often the most reliable path to keeping an installed system running without a costly full changeout. Verify the compressor model, voltage, and refrigerant on your existing nameplate before ordering.
