I'm having issues with my ac and being super handy and broke I decided to fix it myself.
So I have no true previous experience with working on air conditioners besides fixing a blower motor and yearly condenser cleaning.
Here is my issue. 2 years ago I had my goodman 1.5ton r-22 recharged. Last week I noticed my suction line wasnt cold. Then my coils inside the air handler froze up. So Im low on freon again.
I noticed oil inside my cap for the service valve. I cleaned it all up and next day I got oil inside the cap again.
I have a goodman ck18-1b condenser. I was looking online to buy service valve cores but I dont know if they are universal or not. No luck finding a parts manual for my unit.
So can someone please maybe share a link here to what valve core I need or recommend a size?style?
The other thing is, once I replace the service core, how do I get rid of the air inside the lineset?
My thinking is, open the high side valve @ condenser and then on the manifold, open the suction side. I would think that releasing the high side gas would push all air down to suction side valve which then I could open a bit to push the air out. Does this make any sense???
I have a friend that has r-22 and manifold. He hasnt really worked on an ac unit in years so hes not sure.
Thanks for taking the time to help me out here, really cant afford to pay someone to do this for me.
