When Changing your car's ac compressor how do you isolate the compressor so you dont have to discharge the whole system?

Shops use a freon recovery system that contains the freon while the system gets worked on. The system has to be cleaned and vaccumed properly to remove trash and moisture or it will fail again or even not function properly.


Your air conditioner wont take any freon high side and low side dont seem to have any freon in the system you dont hear the compressor kicking in either whats wrong?

Take this to a professional. You have neither the tools nor the expertise to repair. If you tried to add freon to the high side, you've already cheated death once. That side has more pressure than the refill can and it may flow from the system into the can and cause it to explode.


Do you need oil and freon in the coac compresser if you dont turn on the ac?

Nope but over a period of time the left over freon and oil can produce an acid in the system but also make sure that you disconnect it just in case.......


At first heat worked but came out the same no matter what setting floor top middle Now doesnt work at all but occasionally will come on asfter about a hlf hour of driving ANy ideas?

you need to have a professional check your "freon" or R-134 refrigerant levels answer dont waste time getting freon level checked, freon is for air conditioning heat does not come from freon check you heater core. it is more than likely clogged up


Where do you put freon in a 96 Bonneville?

It does not contain any Freon (R-12). R134A is the proper refrigerant. My advice to you is to let a professional do the work. By reading the question you are not qualified to charge the unit, because you dont know where to put your gauges on the system.


How many cans of freon do you need to recharge a 96 gmc safari when its complete empty just replaced the condenser.?

you dont considering you replaced the condensor and opened up the pressure in the system. It needs to be taken to a shop that can vacumn out the system so it will take all the freon it needs. If you do not do this, you ac will be half as cold.


What is the freon capacity of a Ford Escape?

For a 2001 V6 (3.0) Escape the freon capacity is approx 32 oz, dont forget that when you add freon that the cans at the auto parts store also have oil in them, so that needs to be subtracted from the 32. Autozone will tell you that your system needs 9 oz of oil in it with the freon, but their system answers are wrong, the system in your car cannot hold this much. A new compressor should have 1.5 or 2 oz in it when you buy it, and then each can of 134a you buy has 1 oz in it, two big cans are about all you need to fill your discharged system. These 4 oz of oil are all you need. Hope this helps.

You added freon to your 2001 Sebring LXi and now it makes this humming noise The air works but you dont know what that noise is?

Did you add an oil charge to the system when you recharged it and did you recharge the system using refrigeration gauges. The system may be low on refrigerant oil or you could have overcharged the system causing the compressor to have to work too hard.
