Finally, slightly open the valve stems on the manifold to purge air, then tighten the connection nuts securely to avoid losing the seal during operation. Stable pressure within the recommended range indicates proper refrigerant charge and compressor function.

Over-tightening can strip the valve stems, leading to expensive repairs. If pressure rises, it indicates a leak that must be located and repaired before charging the system with new refrigerant.
Fluctuating or extreme pressures suggest issues such as low refrigerant, a clogged filter drier, or airflow problems. An AC gauge hook up to a vacuum pump allows technicians to pull a deep vacuum, removing air and moisture from the system.

Reading the Gauges and Interpreting Pressure Once the AC gauge hook up is complete and the system is running, the readings on the gauges provide vital information about the system's health. These are usually found near the compressor on the condenser or the accumulator/receiver-drier.
