What steps does one take to complete refrigerant recovery?

In order to have a successful refrigerant recovery, one must ensure the manifold gauge is set, set the valve, monitor the pressure and gross weigh while filling, and shut off the valve once the ideal pressure and weight are reached.


What is a TXV valve?

Thermal Expansion Valve is a type of metering device which is one of the separation points between the high and low pressure sides of an air conditioning system (the other being the compressor). It depressurises the liquid refrigerant which passes through it, ensuring that low pressure liquid refrigerant is passed on to the evaporator.

How do you refill the AC refrigerant on a blazer 1995?

You only add refrigerant thru the LOW pressure valve. First check the pressure with a pressure gauge (should read between 25-45 psi) If low then start engin and turn AC on high. Attach refrigerant canaster to the low pressure valve to release refrigernt into the system. Canaster turns very cold and condensation appers on it as it releases into you a/c. Recheck pressure to make sure that is is at the proper PSI. You will hear the compressor kick on and off and the gague will fluctuate between the proper range.

You cannot increase steam pressure through a valve without adding heat to it. Throttling steam always reduces its pressure.


Where is the low side port for recharging the AC on a 1998 Buick Century?

1999 Buick Century low pressure A/C valve for adding R-134a refrigerant (freon). The low pressure A/C valve is located in about the upper center of the firewall to the right of the heater core inlet and outlet (right side - as if your sitting in the driver's seat). Look for a black plastic cap behind the transaxle (red-handled) dipstick.
