I don't think I have a leak as its been 2 months and the same type of cool air comes out, just a little to cool you. Well I hope not anyway !! Thanks for the Info.
You always have to change the Dryer filter anytime the system is opened. The filter traps water, dirt, oil etc.. Must must be changed otherwise you contaminate the system. Expansion valve should be changed just as a precaution, as with all the work being done it just makes sense to. Especially if on there for a long period of time. This can mean a ok system or a super cool system.
Not sure if the A/C guy would have the part but should be easy to get.
When you have it replaced make sure they date the Dryer so that you know when it was done last.
I find most people that have bad a/c systems in the 164 have bad service. No replacement of A/C dryer, expansion valve, improper oil, oil amounts, etc. Just a half-assed job.
