In Sub Zero Temperatures An Air Test Is The Recommended Method For Testing Water Lines.

Low pressures in evaporator (low side) and condenser (high side) How to find the pressure switch in your a/c system. The operating pressures of an air conditioning system are determined by the type of refrigerant used not the size or configuration of the system.

If They Are About The Same, The System Has Equalized And You Can Record The Stating Pressure Reading.

Measure & record the current & voltage of the compressor. The test pressure shall be maintained for at least 10 minutes. How to test ac pressures with a manifold gauge.

Check The Pressure Of The Air Conditioning System By Attaching A Low Pressure Gauge From A Refrigerant Recharge Kit To The Low Pressure Fitting, Located Between The Accumulator And The Compressor And Marked With A Capital L.

High humidity and airflow velocity across the evaporator and condenser have a direct effect on pressure readings. If the piping is tested pneumatically, the test pressure shall be 110% of the design pressure of the system. This can be helpful in a/c diagnosis.

1.5 Times The Maximum System Design Pressure But Not Less Than 100 Psi ;

To conduct an air pressure test acceptable by the code and inspectors, follow these steps: Measure & record the total air flow from the unit. 1, set the ac controls to max and recirculate 2.

Measure & Record The On/Off Coil Temperature.

Pressure that is too much lower or higher shows there is a problem. Total leakage measured with a pressure differential of 0.1 inch w.g. Start the engine and turn on the air conditioner.
