Fixing a window AC unit

1 Upvotes

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.

This is going to be a dumb question but I've been looking to buy a SteelSeries Apex Pro TKL keyboard. That's great because they have blackfriday sales on the US-EN keyboards. Awesome you would say..... BUT I'm looking for FR layout and those sales don't apply [violin plays].

Here's the stupid question:

Can I buy the US-EN layout and then just purchase a set of FR key caps and replace them? I assume I would need to change the layout in software and maybe even purchase a couple of stabilizers but I would think that would be ok? Is that a viable solution? Or is there something more I'm missing that would make this impossible? (would it also require a different plate?)

Thanks for the help

MotoGP is free falling in terms of spectators and followers but it makes sense, there’s no idols anymore now that Rossi is gone and Marc is down, and no one coming from behind, maybe Acosta?
 in  r/motogp  Aug 08 '23

It's not a lack of idols as much as a lack of competition. MotoGP right now is basically just Ducati at this point. They have so many bikes that there's no competition in the constructors and they've won all races but 2 this year so far. Who wants to watch a one-constructor championship? I can go do that in F1

It's nice seeing Aprilia and KTM challenging at the top sometimes but it's still way too infrequent and they're still struggling to challenge for wins.

Add to that that the two most talented riders on the grid Marquez and Quartararo are in no-man's land on bad packages atm, + the fact Suzuki left, and that just makes for a boring championship. I actually thought of canceling my subscription more than once this year. And I probably will next year if it's just more of the same.

I have prime, get my moneys worth. But every now and then I cancel it. Every time, I have no clue how to do it and need to get a human involved.

LPT Request: What is the fastest way to fall asleep at night?
 in  r/LifeProTips  Jun 21 '23

This works for me to some extent. It’s also my go to recommendation. Your room should be cold. My gf hated it at first but now she can’t sleep without the AC on max

 in  r/LifeProTips  Jun 21 '23

I’m the same and this is by no means a full solution but have you tried making your room really cold? This has made things a little easier for me but it might be really specific to how I deal with warm temperatures.

My dog can’t watch me having sex since it’s always facing the other way. You’re welcome nerds.

Trying to find this vintage tv, $5 bounty to anybody who recognizes it.
 in  r/ElectronicsSalvage  Jun 09 '23

I think you might be looking in the wrong erra. 80s tv we’re starting to use segmented digits and the 13 channels here are different. Maybe it’s a 70s tv. Late 70s early 80

Apple Vision Pro, thoughts?
 in  r/virtualreality  Jun 05 '23

In that case the field of view would need to be something along the lines of 60 degrees for it to be truly retina. Since they’re more likely in the 90-100 range that would mean a pixel density of 36-40 per degree which is top of the line but still not as seamless as they made it sound. It does compete with pro solutions though so I’m guessing that’s their market. It’s just really weird that they demoed it for consumers

It will but it’s just yet another barrier to entry for porting and compatibility. Though I’m sure they’ll have some controller at some point for a high price

This was the part that tripped me, I think the headset is much thicker than we think and that alleviates a bit of it. Also didn’t look like they were using pancake lenses. During the presentation they said that the pixels were small enough that they were seemless but they never once called it retina which is their big thing. So I’m going to go out on a limb and say that they aren’t near the retina experience that they made it sound like

It has plenty of glass. I actually suspect that the battery being external is exactly because it’s riding the weight limit already

It’s really impressive but it’s identity is all over the place. I would be less concerned if they tied into existing ecosystems but that’s really not what they seemed to be doing. This looks like a tool for professionals (if developers provide adequate support) but marketed as a consumer item. So weird.

Honestly, if they come out and say “we support openVR and added some onboard support for good super resolution (AI or other).” I could get behind it. In the meantime I’m going to be cautious because I don’t see them driving enough volume to justify developers building a meaningful ecosystem.

It’s a fundamental problem, you interact a lot with things you don’t directly stare at. It’s incredibly annoying to have to look directly at stuff you interact with (in fact eyes tend to shift away right before you interact). It’s one of those things that isn’t obvious until you’re stuck doing it. Now I assume apple is making the bet that this is something people can deal with until it’s second nature (I’m sure the first mouse interactions were weird), or they have some permanence set up so it feels natural. But in general user experience is something they are typically really good with, that said I still would be cautious since they still haven’t really demos anything

I’ve dropped my quest 2 a couple of times. $3500 for a glass headset, I’ll pass.

Also, big screen and motion are fine in the quest 2 let alone the 3 coming out soon. The use cases where the Vision pro make sense are only professional and not consumerlevel at all. Like using it for extra work monitors, or maybe as a loupe for electronic soldering, again pro use cases. But again you can do those much cheaper currently.

I see this as a chicken and egg thing, I don’t know that the developers will join without the consumers, and I don’t think the consumers will pay 3.5k

So does art, even though this looks like an exercise in classicism, the medium is modern (3D render). And the old pudgy men get posted alongside a bunch of other stuff, it’s just that it doesn’t get bumped up to the top. In my experience naked women are actually not the majority of content in artist geared channels of communication. Hence why I said the real question was why do the naked women make it to your timeline. The answer is probably that it’s more popular and gets more upvotes. Not that it’s more common.

For the same reason 21st century people are using the same English words that have been used in centuries past. It’s not a lack of talent or inspiration. It’s because it’s shared knowledge and language. And in this case also an hommage to past artists and probably an exercise in a specific style. If OP had illustrated an old slightly pudgy man you wouldn’t have thought to say anything even though I can guarantee you that artists have been drawing those for centuries too.

Artists (especially classically trained) are obsessed with the human figure in general. Individual artists will have their own preferences but ultimately there’s a bit of everything out there. The real question should be why are the female form ones being selected by algorithms to show on your timeline.

It didn’t come completely from left field. I remember reading a couple of French articles about it. I just never put in any effort to checking their veracity. And I don’t care enough to go dig around again

The comments section. I just don’t get it. Asking for the name of an actress is one thing but all the people out there commenting things like “oh what I would do to you…” type shit.. why? Nobody of value is going to see your comment.

You just need to watch a few episodes or compilations on YouTube. The video posted will really only speak to the crowd of people familiar with his show. It really only shows how little of a fuck he gave
