Yes. All refrigerant must be recovered and stored when opening up an AC system for service. This is not a DIY task, and should not be attempted by someone untrained in HVAC systems.
of course.
Not without converting the system to R-134a and replacing the compressor oil.
you cant unless you have a a/c recovery machine.gm Jim
When you are replacing a compressor. Chances are that the compressor's internal motor had a burnout when this happens the there is a chemical reaction that makes everything very acidic this in-turn contaminates the refrigerant as well. The old refrigerant would be reclaimed and sent to a a reclamation center where it would be incinerated under the guidelines by the Dept of EPA .
The oil is in the freon along w/leak detector.
1 hr maybe. it's like replacing an alt but you will lose some freon & have to pay for a charge.
The ac system will have to be drained of freon and the pressure released. Then the compressor can be removed and replaced. Replace all o rings along the way as well.
No there is no freon in the heater core just antifreeze. The heater core is nothing more than a tiny radiator.
The system will need to be drained of Freon and pressure. Then the lines can be removed and the compressor replaced. Change all o rings during the procedure.
Purchase a Freon recharge kit. Connects the Freon hoses to the ports on the air conditioner compressor. Release the Freon into the compressor.
This is normal it does it to cycle the freon
