Ok and when you set up your gauges to the system high and low side how do you know what temp/pressure your looking for?

i was told to use the gauges and a pressure temp chart and the pressure the system should be operating under. It was not a good school. Is this correct? I guess my question is how do I know if the reading is good or not?

Not a good school. Can you please help me here. My one confusion is the usage of the pressure temp gauges.

Something like look at the needle setting on the guage,(your pressure reading).Follow the needle to the freon you are measuring. (R-22) this your gas temperature.Something like that. Get the books out.

The readings will vary by the conditions of the individual day, and house.

The suction side reading will always have to be above 32 degrees. Get a super heat slide chart.

Study the books you got.
