Ugh diagnosing AC sucks
Most Definitely!
Hey mike the next time after you vac the system do not start the michine hook up the can turn the can upside down and open up the high side and it will suck in the liquid then turn the can right side up and shut the high side and open the low side and start the michine and it will suck in the gas. The compressor will not come if the system empty because of the low pressure switch in.
Thanks that helps! Good tip
You should alwags charge through the highisde first to see if there is flow through the system. If that lowside gauge doesnt rise, that valves is bad
Good Tip
your hired lmao , love your channel USAF BILL
Thanks man
without specification for the specific peace of equipment your just guessing. gauges with red, green, yellow is meaningless. overcharging is just as bad for the system as undercharging. I do automotive a/c and it can get complicated! My best suggestion is leave to the professionals. Lets just say if I recreated this video I would be facing fines and or loose my license.
I hear you man it wasn't a how-to video it was me just getting it done I tried to get people over here they are too busy and it's too hot!
@@DIRT-BOSSI totally get it, number 1 thing I hear, it worked last time I used it! Here is a dirty little secret, anytime you turn air on in a newer vehicle it engages the a/c system even if you have it on hot. This means your putting wear and tear on it summer and winter. I tell people to think of it as an oil change, every 4 years have your system evacuate and recharge. The system requires OIL along with refrigerant that breaks down over time. The best time to do this is the winter time. Or it's like everything else you won't know you need it until you do. Love the channel though, keep on keeping on!
@@vinnyhern That definitely makes sense man! So overlooked
@@DIRT-BOSS Absolutely wrong. Refrigerant never "breaks down or gets old". Unless you have a component failure or leak you should never go into a system. Anytime you do you are taking a chance of introducing contaminates into the system. Especially from a shop that uses a reclaim machine where they pull out the charge and recycle it. You are mixing your system with everyone else they have hook too. This is an up sale that shops use to make money. Now as far as your video it was entertaining and I know you're not an AC guy so I won't bash you, but I will warn you it is a 10K fine to release refrigerant into the air so that part about over charging and just letting it go is a big no no. I know everyone does it but not everyone puts out video proof of them doing it. Just putting that out there for your protection. Too get your charge right, run the throttle up about half way. Turn the AC on high and close the door. After the cab is cooled down look at the sight glass if there are still bubbles it is low. You want to slowly add gas to the low side until the bubbles clear up. Add a little and wait, then do it again. You have to give the expansion valve time to react.
@@topshelf321 got ya! I did discharge it into a can though not in the air! Also in the sight glass it looks like gray fluid passing That's normal correct I don't see actual bubbles.. what color should it be when it's full?
Well, if you were in South Louisiana A/C a must cause it was 92 degrees. You save yourself a lot of money doing your on work, take care my friend keep hydrated stay safe and God bless.
Thanks bud
Boss, I remember when Freon cans cost a buck and a quarter! It took all afternoon to charge the system but, you normally only had to do it once a year…. Then, they came up with this fantasy about the ozone layer. Ice cold air conditioning turned into cooling and the refrigerant jumped to ten bucks!
Now that we are a couple of generations past that…. I just take my pickup into the dealership and take advantage of their spring tune-up special. This year it cost me a bunch to have a couple of o-rings replaced.
I hate progress… when it costs money just because of imaginary sins that I need to pay for!
Oh yeah… sorry for the rant. I enjoyed seeing you tough this out while refraining from dropping expletives!
AND they were called "R12". Do you need AC or just "COOL" by nature (like DIRT BOSS?)
@@sonnyblazer5504 I just drive with the windows open most of the time! Saves on fuel economy and… wear & tear on the AC.
Wanna buy a case of R12?
I definitely hear you
@@sassafrasvalley1939 yea and fill your cab with dirt... no sense
Very glad you did this for us! We normally don't get involved with AC until we have a problem. Too many people walk into a parts store & see all these cans with fancy gages and really get misled. You did a great presentation be it for equipment, car or truck! (Just check what SPECS you need!) Thank you for the time in this one & be COOL!
Thanks Sonny
How did you learn to repair and service the ac?
Trial and error
Mike you got some patience!!! Glad you got it to work hopefully it’ll be good down the line great job as usual!!!!
Thanks
The low side should be 10 to 20 psi
Well that makes more sense to me then!
We appreciate all the videos you put out. I would say you saved a grand doing it yourself.
Thanks bud yeah probably
BROTHER PLEASE ONE VIDEO AC CLUTCH REALLY LOCATION VOLVO EXAVATOR SHOW ME PLEASE 2010 models
Get yourself a pipeliners cloud umbrella for shade and rain and a magnet sweep to find bolts and nuts that are dropped.
I’m having the same issue on the 51
@@Clemexcavation mine was plugged expansion valve replace the filter dryer also
Get a micron gauge. Bring it down to at least 500 microns. Gauge is inexpensive. Get yourself a blue moving blanket put where you're standing much easier to see what you drop and nothing bounces, also good to lay on.
Thanks
You need to put the a/c can up side down for changeling. You need it to be a liquid not as gas. Right side up and it's a gas . Two hands on the can and shacking it will help to warm up a little . For installing Lock it all your labels. one sued tale you . A/C R134A and it hoes 1lb . 3oz ???? Keep the work up. doing good.
Thanks for the tip
Always something with the AC on heavy equipment every year. Always something breaking with heavy equip all the time. Seems persistence is the one tool that always works though. Thanks for the video.
Great job pal! You should get yourself an EZ up tent to beat the heat and rain when wrenching. As a roofer I have a magnet on wheels for picking up nails around the houses. It works really slick, you can grab one for about $100 at a roofing center. That will be helpful for finding that nut or bolt you drop in the rocks. You will Literally find it in 1 min as opposed to crawling around on your hands and knees- headache saver. Looking forward to the next video!!
True!
Mike slow down, your fingers are trying to keep up with your word’s!! Another thing to worry about, but Dirt Boss is “Locking the hubs in” as Muddyfeet says, and getting it done 💪💪 Looks like we are into some weather changes, stay safe and keep sharing. Thanks Mike👍🇺🇸
Lol
Excellent educational video. No belly panel to take off to get to alternator, maybe though the cabin floor, just spit balling here. Could you stake down a tarp to work over, always enjoy you videos.
Thanks there might be a belly pan I haven't looked in that department yet!
D-Boss! i went through all that with my cat mini with the high side way up and the low side down and no freon going in, called my AC buddy and he thought about it and said… clean out your condenser with a air gun, tons of dust and dirt came out and everything went nice a nice, cab got ice cold and it didn’t need any freon, just some dusting…definitely keep that and all the coolers clean.
Thanks Man
I was always afraid to mess with a/c units. See a guy blow a can of refrigerant up in his hand once , don't know how it happened. I have an old recharge unit , don't use it though. Good job.👍👍
He had the high side gauge open that puts all the pressure into the can
First do a nitrogen pressure test for leaks. Then a micron gauge for a proper vacuum. 500 microns is good. Cheers mate!!
Thanks!
Hey Mike there should a sticker somewhere on your machine telling you how much refrigerant system holds. Just like all cars have a sticker stating this info, i would think this would also.
I looked couldn't find nothing
Interesting DB. I put a mini split in my house based on videos and manuals. Had to have someone come out to put the digital analyzer on it. Turns out it did not have enough of a precharge for the system and was low, but works well!
Nice!
My new favourite channel! I learn so much from your videos legend!
Life's like a garden dig it lol
Awesome
Get you a micron gauge, takes a lot of time out of vacuum and waiting to see gauge movement also you will see the smallest of leaks during regain.
Thanks
You need to get yourself a operators manual for the pc88, it would tell you about refilling the AC :)
Yep I only have owners manual not shop manual
Always good to do your own work when you can
You learn about your machine and can diagnose problems easily
Good video Mike👍
True statement
Get a 30lb. jug.
@@mobileair6416 I did what a difference!
It gets really tough when you're the only man on call and you need to get her done. Sometimes just not enough hours in the day. Be safe and cool. 8-)
Yup for sure
Great job Dirt Boss. You always show the unvarnished truth which is greatly appreciated. Got up to the low 90's here today too, so I know you were sweltering in the sun doing that work!
Thanks Dale!
If only you knew a guy that could pour a nice concrete pad and get you outta the rocks 🤔🤔
😁
Always something to work on, weather you want to or not 😬
You seemed to get it somewhere near right, reading the comments there are plenty of people who know what they are doing, pleased they are more than happy to pass on their wisdom to you !!!
Thanks man power of UA-cam
Glad you got cooling back, I like those cans they make recharging easier and no license required
Yes sir
Never reuse o rings
The evaporator by the radiator should be changed also
The round cylinder I change that also... I still get hot flashes every 40 seconds heat comes through the vent not sure what's going on...
You should not see air bubbles in the sight glass
I'm not sure it was air bubbles it looked like it was just gray fluid
You need a shop man
Yes yes yes
👍
Thanks
👍👍👍👍👌
💪🏼
By allowing refrigerant to escape to the air you have subjected yourself to a 25k fine from the EPA. LEAVE it to the professionals.
Good job Mike. I hope it stays cool for you now.
Thanks buddy
