HVAC gauges should read the system's refrigerant pressure and temperature. The exact readings will vary based on the specific circumstances and type of system being used. It is important to refer to the manufacturer's guidelines or consult a professional for accurate interpretation of the readings.

What you need to do first is read the pressure gauges and see if the gauges read 0 psi
To read the gauges while charging a home AC unit, first ensure the system is running and the gauges are connected to the service ports. The low-pressure gauge (usually blue) should read between 25-45 psi for proper operation, while the high-pressure gauge (usually red) should read between 200-300 psi, depending on the ambient temperature. Compare these readings to the manufacturer's specifications for your specific unit. If readings are outside the recommended range, adjustments may be needed to charge the system correctly.

Anywhere as long as it is not in either extreme position, Remember gauges are just an indicator and not "gospel"
