A/C compressor oil after condenser exchange

Hi,

 

both of my condensers were leaking, so I had replaced them. The system was already completely empty.

 

A workshop refilled the system with 900g R-134a and only 5g oil. I doubt, that they have filled up enough oil. As per manual the total qty. is about 195g and about 20g remain in a single condenser.

 

So for my understanding at least 2x20g of oil should be added for the replaced condensers and an amount for the oil that escaped together with the refrigerant.

 

Am I wrong or what is the best procedure to determine the correct amount of oil.

 

I think adding too much is also not a good idea?

 

Thanks for any help!!!

Since your system was completely empty, you have to go with the total technical data amounts, not just what is calculated for the condensers.

As I understand the manual most of the oil remains in the system. Isn´t it too much, if I just fill up another 195g? 

 

What could happen, if I fill too much oil?

You risk major problems.  If you are unsure how much oil is in the system, it can be flushed clean with a special solvent and than recharged from scratch, but that takes special equipment.
