Air compressor started making noise and I had a great deal on a Denso compressor so I bought it.
Had a shop evacuate refrigerant, then installed the new compressor.
Had the shop re-charge it, but now my system high and low side are both overcharged. (95f ambient, readings are 60psi/355psi at idle, should be ~55/275)
Reviewed my process and I did NOT measure the oil from the old compressor. I just installed my prefilled new one. I didn’t account for the remaining oil in the rest of the system. I’m guessing I’m oil logged.
Today, I brought it back to the shop to have refrigerant recovered again and asked them to weigh it so I know if it’s overcharged with refrigerant or oil. Next I’m going to take it home, pull the compressor and dump out some oil.
Online estimates say around 2ozs of oil remain in the system. The new compressor came prefilled with 5ozs. I’m going to dump out 2ozs of oil and re-install my compressor.
How does this plan sound to you? Any critiques?
