BigBob :

Greetings and welcome back to just answer!!!!!

Customer:

thx

BigBob :

Yes usually you drain the old one, but since you did not get any out that is obviously not possible. I would add 2oz in this case. The factory spec on a totally drained system is.

BigBob :

Refrigerant oil
Capacity of components






























Condenser35 ml (1 1/6 fl oz, 1.2 Imp oz)

Evaporator40 ml (1 1/3 fl oz, 1.4 Imp oz)

Each line and hose10 ml (1/3 fl oz, 0.4 Imp oz)

Compressor210 ml (6 fl oz, 6.3 Imp oz)
Customer:

If the compressor is supposed to hold 6 why are you suggesting only 2?

Customer:

my understanding on this is that too much or too little the system and it will fail

BigBob :

Because you did not get any out of the old compressor. That means it is still in the system and too much oil can cause the system to not work properly or not work at all. Rule of thumb is 2 oz when nothing comes out. Did you turn it upside down and spin it?

Customer:

i did not spin it but I am going to go do that right now-stand by

BigBob :

no problem.

Customer:

nothing came out-if 2 oz is not enough what will happen?

BigBob :

Give me just a second to check something.

Customer:

i have also read about having the system "vacuumed out" before recharging to remove any old oil. is that true or not?

BigBob :

Yes that will need to be done. That removes all the moisture, at the same time you drain some old oil, then the machine can put the same amount back in.

Customer:

so is it better to add none and take it to a garage?

BigBob :

Yes that would be the best. Then when they vacuum it they can put the same amount back in. Just let the shop know what you have done.

BigBob :

I would still add at least 10z so the compressor is not dry. Does the new compressor come with any oil in iy?

Customer:

does this need to be a dealer thing or can my regular guy do it?-I know they do a recharge service

BigBob :

Does the new compressor come with any oil in it?

Customer:

no-bone dry

BigBob :

No you do not need the dealer to do this, any qualified ac repair shop can do it.

BigBob :

Put at least 1oz in it then.

Customer:

ok-thx i guess we are done

BigBob :

No problem if you have any further questions just let me know.
