Fixing a window AC unit
Hey everyone.
Over the years, I've replaced a few window AC units because their performance would drop, and cleaning them was no longer yielding good results. They wouldn't flat-out stop cooling but would just perform worse and worse over time until it was no longer worth it.
My understanding has always been that it's cheaper to just get a new unit than it is to repair an existing one if it isn't an electric fault.
Recently, the AC unit in the bedroom has been starting to decline and I've been entertaining the idea of a DIY fix. I have an electronic/software background so I'm not too concerned with those types of issues, but when it comes to compressors and refrigerant I could use some help/advice. Especially in systems that would likely require a tap/valve being added to service them.
I guess I'm still in the analysis phase right now and am trying to figure out if there are any long-term benefits to figuring this out. I'd be willing to spend a bit to get tools that I could keep using over the years, and I can see the benefit of making an AC unit serviceable for the future. Plus, this knowledge could help fix fridges in the future as well.
I just don't know 1) how much it would cost for tools and for parts with such a project 2) if this is even something I could pull off (I have some lingering questions about the safety of putting a tap in a system potentially full of refrigerant)
Any information about costs and advice about doing something like this is welcome.
PS: All else failing, are there any brands with serviceable window AC units on the market?
Thanks all!

Thank you! Exactly what I needed to know. Sounds like I'll need to figure something else out.
