The Lennox 90W65 is a genuine OEM Interlink AQA036KAA scroll compressor rated at 36,000 BTUh (3 tons), running on 208/230V, single-phase power with R-410A refrigerant. This compressor drives the refrigeration cycle in your Lennox outdoor unit by compressing low-pressure vapor into high-pressure gas, allowing heat to be rejected through the condenser coil. The orbiting scroll mechanism provides smooth, low-vibration operation and excellent seasonal efficiency.

Common Failure Symptoms

Warm air from vents while the outdoor fan still runs
Compressor won't start or trips the overload repeatedly
Buzzing at start-up followed by a shutdown
Abnormal noise, vibration, or oil leakage at the base

Why OEM Matters

The factory-authorized 90W65 is matched precisely to your Lennox system's tonnage, voltage, and oil charge. Generic replacements risk incorrect displacement and lubrication, leading to reduced capacity, higher energy bills, and potential warranty issues. Installing the correct OEM compressor protects your investment and restores the rated performance Lennox engineered. Ships same day when ordered before the daily cutoff.
