As the owner of a 20+ year old car who likes to do his own repairs, this explination is PRICELESS! The more things I repair successfully, the more confidence I get! This video provided me with information that will no doubt help me when my system needs some tlc.
Been a gear head all my life and im a licensed stationary steam engineer....you just explained thermodynamics and dianostic examination better than a 5 thousand dollar class lol. Very good job man. You should consider teaching.
I'm an electrical engineer and I do some work on my cars myself and I asked my aircon specialist friend to explain to me how to DIY it but I couldn't understand a thing on what was saying. But this guy explained the basics on such a scale that everything is so clear than it ever been. Really thumbs up.
That was an excellent video on AC systems. Very well explained. I like the fact when he keeps saying you don't need a $4K machine to do this king of work.. So many other videos say never be a DIY & do this kind of work. This just isn't true & he proved this. Thanks for making this very informative video..
Excellent video! This is the first time someone has explained some of the basics that can cause symptoms that I have had in most of my vehicles. I wouldn't mind a 3 hour video to understand every symptom and how to repair it completely.
I can listen all day and willing to learn the basics of AC systems. I’m a Journeyman Wireman for 30 yrs but AC is totally different.Thanks and I’m a new subscriber now.
One of the best explanations on how the car air-conditioning system works. Thank you so very much for sharing your expertise. I really enjoyed watching the whole video. All the best and best regards.
I'm not a diy'r as cars are too complex these days but you gave me enough info that I can if the repair place is trying to roll me over.. Thank you very much!
Excellent video! So glad I watched it. I have an 06 CRV with a new compressor replaced last year. During the summer it was cooling so well it would absolutely freeze me. Oddly enough I noticed on a warm day in December it wasn't cooling. I assumed the coolant had leaked out and got one of those DIY kits from WM to put some coolant back in it. To my surprise, when I hooked up the hose to the low side, I got high pressure in the red range on the gauge. Now, I at least have a clue as to why the low-pressure side is high. I did not have the expansion valve replaced when I had the new compressor installed! What seemed like sorcery and rocket science before now kinda makes sense! I'm going to my guy and have the expansion valve replaced. A/C starting to make sense. This is scary, but fun! 1000 thanks for a great video!!!
Thanks for this. I took my car in to a mechanic to see why my AC wasn’t working, and it turns out my entire system had corroded. I didn’t understand what that meant, but this video really helped me visualize it and look into what parts I might be able to replace for a stopgap
Good video, tutorial on how the Car AC system works.Great for the beginner.Simple and clear explanation.Tqvm and Salute you Sir for sharing the knowledge.🎉 Greetings from Malaysia.
Great video! After vacuum, does my system require me to inject the full volume of oil stated in the specification? Or will some oil remain in the system? How will I know how much oil remains in the system after vacuum?
Thanks man! this helped me diagnose a bad wire that was intermittently turning off the fan. I noticed the high pressure would increase all the way beyond 300 as I filled in freon, even with 4 oz in the system. I thought it was a clog or something, thought the expansion valve was bad. If I just knew a little foundation to the AC system I would of known instantly the fan wasn't cooling the condenser, duh!. Thank you!
I was a GM tech at a dealership like… another lifetime ago lol. Its amazing how much you forget. Great video, spot on info! I’ve always felt that techs should be pro’s at the basics before giving them the fancy tools. I was relegated to gauges until I earned my salt enough to use the snap-on machine that did everything for you.
Interesting video. My ac starts out cool in the morning and as the day warms so does the air coming out the vents. And it stays that way doesn’t fluctuate. First I thought it was my condenser but from what you explained in the video, I’m now thinking expansion valve.
Thanks for this! I have a mid engine application with the condenser in the standard position in front of the radiator at the front of the car, and an electric rad fan pulling air through the condenser and radiator. Consequently, the refrigerant lines are much longer than in a normal installation. Is there an accurate method of determining the optimum oil in this system?
I really liked the way you showed different readings and explained the issues. My 2007 Honda Accord's AC is acting funny. Readings are good, compressor engages and blows cool air. After about 10 mins of the compressor cycling on and off it goes off and pressures change. Low pressure goes to 50 psi and High pressure goes to 100 psi and it starts blowing warm air. If you turn it off and let sit a minute and then back on its fine for awhile. any ideas?
Great video! If I got my vehicle's AC system completely evacuated (via a Refrigerant Recovery Machine), do I need to put the full amount of oil back in? Also, is the amount of oil to put back in based solely on how much oil the compressor requires, according to the service manual?
This was an awesome vid thank you for posting it. What do you do if you can't find a leak? I added dye to my car, the low side pressure is 5 psi and the high was 90. Temp was about 90 deg outside. I drove the car around about 20 min, and didn't find any leaks with the uv light. A shop charged my a/c system last summer. but now A/C just blows hot air. Temp at the vent is a100 plus.
Really good video sir and your material was spot on. One suggestion would be that once proper condenser fan operation is verified, always place a really good fan in front of the vehicle to replicate air across the condensor while driving when reading and/or adjusting pressures.
Great video and excellent presentation of the information. Is there a chart that will relate the temperature and humidity to what yoiur pressure gauges will show?
Young Techs should take heed to this ..To have a 609 a/c and air conditioning certification is good to have ...Alot of techs and mechanics in alot of shops they do not have it
@@RustbeltMechanic For the most part what the younger Techs need to know if I can remember so that when they hear testing so that they do not get discouraged is that the test is not as sophisticated as some other test and if my memory serves me correctly I believe there were like 13 to 20 questions if less I believe it's been quite awhile but it is a simple run through
I'd say the HVAC ASE is far more extensive and actually requires a solid understanding of the entire HVAC system. 608/609 is simply for EPA standards. 608/609 is easy to get and doesn't cover all that much TBH. Get your HVAC ASE! Get all your ASE's while you're at it 😉
PAULY'S AUTO agree..... the automotive hvac ASE is very extensive and definitely pressures towards knowing a lot more electrical than even pressures anymore. I wish it focused more on hvac pressures and recovery machine usage as well. A lot of the students look at an ac machine like it’s a spaceship lol
I'm impressed with the way you teach congratulations, i have a question i will replace my Compressor, Condenser and the 2 Expansion Valves, i will flush all the line and the evaporators, the compressor is already oli filled with 6.8 oz and say you need to add more oil if you have read evaporador that is my case, but the FMS said my system should be fill it with 5 oz oil, this new compressor works with 6.8 oz so i don't know how much oil i should add for the second evaporator, could you help me ? thanks
Would you explain how(or if) that machine tests the vacuum before you charge the system. Is it automatic or manually done? I took my vehicle to a shop, told them I replaced the compressor & Accumulator and asked them to "check it and charge it". They said the machine did not report a leak but 3 hours later dye had leaked out. Just want to understand what happened. Why did they not detect a leak.... Should I have said "Test it, let me know if needs repair." instead? I wanted a shop to do it in case I needed to use compressor warranty. Now I am doing it myself because they charged it with 16 oz too much and probably Denso won't warrant it anyway. Your answer is much appreciated. Thanks.
Excellent job sir, you take your time explaining yet are concise and don't mince your words. Loved the diagrams and walking through the physics of the entire system, I have only seen videos of people talking about and pointing to parts on the vehicle and it's hard to follow along.
Thank you for making this useful info video. I’m trying to do some last minute studying before my HVAC auto class ends for finals and for my ASE cert test. I’ve been kinda confused here and there throughout the class about this topic but this was just the refresher I needed. Thank you👍
This is the best video on UA-cam I've found on ac systems for DIY mechanics like myself. Very easy to follow & very informative..Many thanks for sharing your knowledge. You have a new subscriber. All the best from England. 😊👍👍.
Trying to figure out where to start on my 2013 Ford Edge.. starts out very cold sometimes it's below 20° I do not have dual climate control but I will soon start to notice after driving the driver's side starts getting warmer than the passenger side seems like as soon as the car warms up or if I shut the car off and turn it back on entire system gets warm. After the initial glance at the system I didn't notice the AC fan was not working at all so I did replace it. Fan works properly now but the issue is still happening. I have checked my actuators at both blend doors do you know if I have leaked freon would this be some of the symptoms of low freon
Awesome video and information. Why would a newly refurbished ac system in 9 months, when I first cranked the car and turned on the ac, it blew oil and refrigerant out of the compressor, almost like a rupture disc blew, but can't fid a rupture disc. Once I turned off the ac, you could hear like a valve closing. Hooked up my gauges and I still have refrigerant and low pressure on both high and low. What do you think might have happened? Thanks.
Buddy ty for taking the time to make this video, I watched it thus far about 4 or 5X. Ironically after I watched it I had Ac diagnostic the next day, high reading on the low side , high side was normal, I went after the exspansion valve, once changed the Ac system was extremely cold. Got the job done like a boss, an grabbed the bag 💰💰ty again.
Nice Video! If I want to hook up the AC manifold to your car to do some measurements for the pressure, should I purge the blue and read lines from air once I connect them or no need as the air will not get into the system? please clarify thx
Outstanding video with clear explanation on auto a/c basics. It would had been great if you had demonstrated the scenario of overcharged systems, which is something common. I have found that a lot of people just "blindly" add R134 when their a/c does not cool sufficiently. I hope to see a part in this series going into a little more advanced scenarios. Thanks for your hard work.
Excellent video! I've worked on 4-5 systems over the years with ranging complexities. All have worked in the end, but I have wondered what the gauges were actually telling me, this is where my knowledge ended. This is a great resource.

Thanks man!
@@RustbeltMechanic you it
Nice video thank you ,was wondering g where I can get the toggle switch relay , all I can find is for fuel pumps ,will they work ?
Good overview. The low pressure moving from a liquid to a gas (phase change) requires a lot of heat which it gets from the warm air making it cold.
As my a/c instructor loved to say "a/c doesn't make cold air it removes heat cause In the a/c would there's no such thing as cold only lack of heat"
Awesome information here bud. Thank you so much for teaching us
My question is , when you are vacuuming the system to vacuum moisture does the oil come out as well ??
I'm pretty sure it doesn't no, not unless you replace a major component like the compressor
