my ac hose just slipped off lol. Can I repressurize it myself or do i have to go to a shop? I wrench but never fucked with that before
>>28710995AC hoses dont slip off you retarded jeet.
>>28711000This one did...
>>28711004Then that means the hose shrank due to time and mileage and the pressed-metal clamp couldn't hold it anymore. You'll need to have the rubber section replaced by a shop specializing in automotive a/c so that they have the tools, or a new hose assembly bought, and the system vacuumed out with a vacuum pump so that there's no moisture left in there and then recharged with refrigerant. Considering the amount of specialized tools and knowledge required you'll probably be better of taking it to a shop.
you can rent the manifold set and vacuum pump, but it's a lot easier and faster to just have a shop do it.
>>28711214manifolds are for retarded poors. everyone has moved on to gauges and VCRTs
this is quite the bait, have a >>28711266
>>28711298Let me guess, you're retarded enough to think you can charge by pressure and not weight. How much of a charge do you think a manifold and 10-12 feet of hose have? You do know the hoses manifolds come with arent vacuum rated either. How many VCRTs do you have, wrenchlet?
>>28711495i dunno but i used a manifold set and scales to charge my system. worked great. and yes i did purge the lines before hooking it up to the ports. i actually let it leak very slowly while connecting them to ensure no air would get into the system
>>28711495and fwiw, while it's not recommended, you can charge by pressure. the refrigerant i used does have a general guideline on their site on refilling via pressure. they also state that it's doable but not ideal
>>28711540An old GOYOTA. Yuck! Ask me how I know that you're poor!>I'm just joking...
>>28711561>and fwiw, while it's not recommended, you can charge by pressureliterally every car or other AC device tells you to charge by weight you retard>the refrigerant i used does have a general guideline on their site on refilling via pressureno MVAC or HVAC manufacturer will ever do this. you just bought some can you jack off in to the system and hope for the best, and if it improves it is only because you were that absurdly low on refridgerant>>28711540>i actually let it leak very slowly while connecting them to ensure no air would get into the systemi've argued with you before i'm quite certain you dont own a micron gauge
>>28711585i wish they were for poors. covid destroyed used car prices...>>28711589literally every car or other AC device tells you to charge by weight you retardi'm fully aware of this which was why i said filling by pressure is doable but not idealit's just a can of propane/isobutane, their doco for charge weights also tells you how to fill via pressure or even by the temps at the ventshttps://hychill.com.au/media/pages/info/b6c03c0450-1578467756/charge-weight-guide-full-doc-120201.pdfit improved a lot because it was originally an r12 system that was retrofitted with r134aalso yea lol, micron gauge is way too expensive lel. especially since i'd probably use it once. that money goes to other car parts instead
>>28711589Keep calling others retards in every post, I'm sure that'll make you feel like a big man like your dad.i.e. calm the fuck down.

>>28711608>by the temps at the ventsalso if you dont have a micron gauge, then you certainly dont have a pair of psychrometers either
>>28711619i feel like that's just a legal disclaimer so people don't go pointing fingers at them if they screw up (like a lot of things already do anyway, e.g. "for off-road use only").i looked up that model of micron gauge and all the local hvac shops sell it for around 450 bucks here. for a tool i'm only gonna use once or twice it's just not worth it>>28711623of course not; i'm not a hvac tech by trade, i just wrench on cars for fun...
>>28711626>for off-road use onlythats for retards who buy poorfag LED assemblies and put them in halogen reflectors, because they blind everyone on the road>for a tool i'm only gonna use once or twice it's just not worth ithow do you know when you've reached <200 microns? how do you even know you dont have a leak without one. >of course not; i'm not a hvac tech by trade, i just wrench on cars for fun...i'm an it guy by trade but here i am with a full set of tools and 608 and 609 certifications
>>28711693>how do you even know you dont have a leak without one.let it sit for 15-30 mins and watch the gauge. for me i started evacuating it at night so i just left mine overnight and in the morning the needle hadn't moved at all.there was also dye in the oil that was already in it, would've lit up like a christmas tree under UV light. also the refrigerant has an odourant that smells like rotten cabbage so you'll know if there's a leakdo you moonlight as a hvac tech or something? me personally i think going as far as to obtain certs is pretty nuts for a hobby, unless of course you're genuinely interested in the field. in any case, congrats on putting in the time and effort to get the qualifications/certs
>>28711706>let it sit for 15-30 mins and watch the gaugeA manifold gauge isnt anywhere near as accurate to display microns.> there was also dye in the oil that was already in it, would've lit up like a christmas tree under UV lightit wouldn't, its not under positive pressure, it wont leak out> also the refrigerant has an odourant that smells like rotten cabbage so you'll know if there's a leakit doesn't people get high off R134a, it is what duster gas used to be> do you moonlight as a hvac tech or somethingno, I just hate people who gatekeep their shitty trades> me personally i think going as far as to obtain certs is pretty nuts for a hobbyto talk shit and mock them. they're open books tests, if you have a couple hours to kill and $50 or so you can do it yourself - mainstreamengineering.com. the tests are pretty much promising you wont vent refrigerant to the atmosphere
>>28711714sorry i meant the HC refrigerant that i used and linked to, they put odourant in it. i ran it for years without any problem. the molecule is bigger than both r134a and r12 so if it did leak it'd be a lot slower.and lol fair enough on the rest, i can kinda relate; one of our local hvac unions/orgs ran a scare campaign about the dangers of HC refrigerants in cars years and years ago. coincidentally they were also sponsored by dupont
>>28711714>A manifold gauge isnt anywhere near as accurate to display micronsi know that now but at the time i was paranoid about leaks so i figured 8+ hours under vacuum would be as good as anything to show leaks
>>28711004Crimped pressure hoses don't "slip off" and YOU won't be able to fix it. The system is compromised by moisture and requires special tools and knowledge you won't look up to properly repair.
>>28711727>i know that now but at the time i was paranoid about leaks so i figured 8+ hours under vacuum would be as good as anything to show leaksAny sort of MVAC system will leak slowly just because there are a bunch of pieces not brazed together, instead just hard lines with o-rings pressed in other parts like the evaporator core and then subjected to heavy amounts of vibration> local hvac unions/orgs ran a scare campaignjust look at how much those cock suckers mark up refrigerants or read their own forums/subreddits. anyone doing residential is incompetent and there to scam you. anyone doing mvac work typically doesnt know what they're doing beyond hooking up some all in one machine to vacuum and recharge you
>>28711765considering the environment of an mvac system i'd be more surprised if it didn't leak, i mean like just thinking about the compressor shaft seal alone and how it has to seal against gas while rubbing against a shaft spinning at several hundred to thousand rpm, it's pretty impressive that they hold up for as long as they typically do. in a proper functioning system the leak would be slow enough that you'd only really need to do something about it years and years down the line.the hvac lobbying is really just an attempt to try to stop diyers like us from cheaply regassing when our cars needed, but thankfully people are slowly starting to see through the smoke and mirrors. yurop have been using hc refrigerants for a while now and im seeing them used in supermarket fridges as well
>>28710995Slap a can in it. It ain’t rocket science like they pretend. You don’t need to evacuate it. Who gives a fuck?
>>28711916Im sure bubba would just shoot freon in it and call it a day but I'm a bit less careless than that lol>>28711730I will neither confirm nor deny that it happened due to a retarded error on my part. And no it doesn't seem worth doing it myself versus getting a shop in this case...
>>28710995lmao what the fuck am I reading
>>28711916If a system is low on refrigerant you can just add more, but it's smarter to find the leak first.If you disconnected a hose and completely emptied the system, you must pull a vacuum on the system to remove the air and humidity first.
>>28711540How hard was this to do, and how expensive was it? I have a car with an AC that should work, but it's empty so it needs to be vacuumed and refilled. I'm a bit nervous to do it
