This thread is my base AC thread for suggestions, questions, whatever...
I run https://granburyautoac.com/ I specialize in automotive heat and air conditioning systems. I've been doing AC work since 1983 and have seen all of the changes, good and bad, that have occurred over the last 40 years. I'm keeping the first post short as they always show up at the top of each page and if long, they clutter up the thread... |

I put oil into the system through the high side port only!
Placing it here means it will be absorbed by the liquid and it will reach the compressor as fine droplets. It is possible to hydro lock a compressor. We call that "slugging" a compressor. It doesn't do as much damage as hydro locking a ICE engine but it can destroy the reed valves inside the compressor thus rendering a compressor useless. Now, when I'm doing a full system and I have everything apart, I place 1/3 of the oil in the compressor sump, 1/3 in the entrance to the condenser and 1/3 in the entrance of the evaporator. Adding oil to an existing system is ONLY done through the high side port when under vacuum. |
