Use Ac Vacuum Indicators

Using an air conditioning vacuum gauge and carrying away mild tests on your method with the gauge isn't a laborious charge. Takings off the metallic subsume access caps located on the air conditioning system. The cap on the high side is large in breadth. The low (or suction side) is much smaller.


1. Bestow the wrench. You can research your system for particular problems or honest perform annual checkups. The exactly reading of the vacuum gauges can clue in you provided there is a blocked filter or low refrigerant commensurate. Install the vacuum gauges on the AC unit, then trial the readings to build positive everything is operating in the groove that it should.

2. Make sure the connection to the hose is tight. Connect the AC vacuum gauge, set to the high side, to the pressure port. Be certain that the connection is secure. Open up the valve underneath the pressure gauge all the way.

3. Turn on the air conditioning system. Look at the difference in pressure of the two gauges on the AC vacuum gauge set. You should see a reading of 30 PSI or under for the low side. A reading of 150 PSI or higher will be visible on the high side.
