Air Conditioning Basic Troubleshooting. AC Beginners Course. Truck AC Class Part 3

[@nicksolomon2340]

Love the video and all your content but usually the biggest problem with a/c systems is a dirty condenser or evaporator, especially in farm and construction equipment

[@cwj9202]

An excellent introduction to air conditioning basics. A note to Scott R -- good point, but I would add that if the clutch is bad, the compressor is not far behind (as a rule); so, for the truck Josh was repairing, entire component change-out was the proper cost effective measure for the truck owner, i.e. no sense having the owner return a few months or a year later to undergo the expensive troubleshooting, evacuation, vacuum, and recharge process all over again. Saves money in the long run. In another scenario such as owner's work, just replacing the clutch is the way to go.

+Chad Jessup Thanks Chad. Good point about the A/C compressor. I think most shops just swap the compressor now, kinda like they don't rebuild alternators anymore.

[@toriwilliams9655]

Answered alot of questions, appreciate it

[@mattd3933]

Hello- was just seeing if you ever did do a electrical AC troubleshooting video? Could sure use some help Thanks for all the great informative videos

[@peterdarlington4117]

Never use a vacuum to test for a leak you are pulling humid air into the system do a pressure hold test with dry nitrogen that’s the correct way to do it Not as big of a deal for you automotive guys but for residential and commercial air conditioning and refrigeration the windings of our compressor sit in the refrigerant and when moisture and the oil contact each other it becomes acidic and that’s why windings short you don’t want to draw moisture into your system.

[@PT-ChucoTown]

I love this video. Thanks man

[@jesustrevizo3148]

Visual inspection good... Get into the electrical side of system

[@hillbillydualsport]

Very good video.

[@pedropedro2837]

Thanks a lot

[@timdulan]

Maybe the next video you could go a little farther in depth of electrical troubleshooting, I really do appreciate the videos brother, keep up the great work!!!

[@AdeptApe]

+Timothy Dulan I'm going to be making an electrical troubleshooting class that will be much more in depth than these quick AC ones.

[@Tomas_Mariscal]

Great video!!!

[@johngabriele6532]

Full of info... Not my issue I'm having though... My question is I have a fluctuation of pressure on my low side Wal-Mart guage which is cutting the freightliner compressor off and on... My assumption is the orphic tube is clogged... I'm heading to Florida this Monday and I do not have a vacuum pump ... Can I change the orphic tube and accumulator add refridgerante with out pulling a vacuum ....

[@dhillonsavee]

As Always The Best I love learning and you are a good teacher.My AC has 2×2 small aluminium box on firewall that is stuck can't recall name , what is that has purpose and another problem i face is water gets in to the vent lines like 400-500 ml dont know from where it comes. Thanks for videos

[@no_name672]

Your AC Drier is bad

[@hinderedstoner91]

Also called the expansion valve

[@shevanjohnson5193]

What if the apad system isn’t lighting up? No power

[@peggycoomes1853]

I just want to know if the bunk air conditioner has a separate unit from the dash air conditioner

[@wisejustice7742]

I am pretty sure I have an electric problem. For some reason when I turn the dial to blow Max Air it does not blow any air but when I turn dial to off it blows for 10 seconds then dissipates. Basically I have to keep playing with the dials turning it on and off as well as the button for in cabin air circulation as well as the AC off button. Please help me with this problem. You said you can put paper clips in the connectors to see if the switches are bad I'm not understanding what that means and how to go about it. It would be much easier if I saw your directions visually

[@alaguilera4121]

Where is your shop adapt

[@javierg335]

What if air doesn’t want to switch to the vents, it stays in defrost , replace controllers still doesn’t switch

[@efrensaclolo7021]

I have been searching for an answer on why my compressor is not compressing ,the system is fully charged,there is no leak , but when I turn on the a c the gauge is not moving and the compressor is not cycling and just continuously spinning.What part of the compressor is failing in this situation?No one seems to answer this question and know the answer.I don't want to replace the compressor if I don't know what causes of no compressions.

[@victorlice8029]

Any idea why I only have pressure on the high pressure hose and cero pressure on the low pressure hose??

[@toriwilliams9655]

I tried adding some on a 2012 cascadia , but I couldn't firgure why no freon was going in the system. Maybe it's filled with air

[@alextepozteco3681]

A lot easier to work on, the busses at my workplace have 1 huge condenser, 4 evaporators, the compressor is basically a motorcycle V4 and it uses about 28 lbs of refrigerant

[@falconheavyraptor]

What kinda bus are you working on that has a compressor that big

[@alextepozteco3681]

@@falconheavyraptor Prevost tour coach, there's a bigger one, Van Hools have a bigger system, a Bitzer W6 and carries around 33-36lbs

[@johnwillis4503]

will it hurt my ac system if I add water bolt values to shut off the antifreeze to the system to make it blow colder. I have a kw 900L 05 model cat motor 475. or what would you suggest I do?

[@ranasaleem4663]

Brilliant

[@bwehfug]

I have ac issues in my truck. Ac works and blows cold for 5-10 minutes. Then it just ceases to blow cold air. It just blows ambient air. You can switch system off for 10-20 minutes, turn it back on and the pattern repeats itself. Any suggestions would be greatly appreciated, as this one has stumped me.

[@highlandwinterwolf8589]

I'm having the same problem, hoping someone knows what's up and hope you get yours fixed soon.

[@alejandroguerra5434]

Did you fixed your ac problem and if you did what was the problem

[@JKVK33]

If you have guages hook up and see what your high side reads if it's really high and the fan kicks on but doesn't bring the psi down check your condenser and use compressed air or a power washer to clean it out, should be good then.

[@papergatorztv7087]

What part would I need to change if my truck is blowing hot moving but cold sitting still? Can’t figure it out

[@eagletran9]

Thanks

[@nedoscarsandfishingvideos5500]

Why not just change compressor clutch

[@shawnbinder8802]

So if the clutch is working on my 2016 freightliner cascadia on air compressor and it’s not turning when ac is on what’s should I look at next

[@shawnbinder8802]

I say clutch is working I can manually spin it but does not spin when I turn on ac

[@jcthe2nd]

awesome

[@fernandogarrido4727]

Where do you work at?

[@johnwillis4503]

any idea what would cause the ac air vents not blowing hard like it should be on high checked the fan motor and switch both are working correctly. any suggestions would be greatly appreciated

[@carlosjackson7018]

Have you ever heard of a 3116e engine meaning electronic injection

[@AdeptApe]

+Carlos Jackson Yes, they are the early HEUI systems Cat used before the 3126.

I was talking about expansion Valve.

[@texasfortruthnomsm7279]

those gauges are junk I bought a set last year and used them on cars to dozers had to replace them this year due to internal blockages

[@AdeptApe]

+Scott Davis Yeah, like I said if you are going to be using them to make money buy some Robinaire stuff or something off the truck that'll last awhile.
