How to Vacuum Down and Recharge Your A/C System! - EASY

Today we are showing you exactly how to vacuum down and recharge an air conditioning system. This is a comprehensive video that will teach you precisely how to service an A/C system in your car or truck. In this video is full lesson on to service an automotive A/C system for free.

The formula for the high side pressure is to take the current outside ambient temperature and times it by 2.2 Therefore if it's say 100 deg that day you would be at roughly 220 psi on the high side gauge. If it's a cooler day say 75 deg then times 2.2 would be 165 psi for the high side gauge.

I've been a formerly certified mechanic for a mere 20 years now(started with my dad, to a business and now on my own).I've been telling people I know jack smack about HVAC on a vehicle. I couldn't take it anymore. Watched this video all the way. Now I can add a new extremely basic service for ac recharges. We are in Texas, AC is year round these days except for 2 months. Thank you sir. This is a blessing from God and you shared your bread with others. I'll cherish it.

I'm a truck driver and doing some work on my truck saves me a ton of money and with just this video you saved me around $2000.00 bucks. I thank you and God bless you.

Man, you just saved me hundreds of dollars. Plus, i love working on my car, i do AC for a leaving, but not for cars. Thank you very much sir!

Typically I am not one to come back and leave comments. However, this time I had to, I must tell you, this is video is very well explained in a simple manner so anyone a bit mechanically inclined can understand and actually pull this task. After replacing my Jeep's compressor, I went and purchased the exact pump from your link, followed your instructions and all worked as described in your video, saved tons of $$$ and time. Thank you very much.

I'm 50 years old, have been working on cars for 35 of those years, and am quite arrogant. But I cannot believe how much I learned while watching this video!

[MissChiVUs]

Thank you very much for your video! Since my husband passed away, I have learned to do many car repairs thanks to kind people like you who share knowledge! I have replaced my vvt solenoids, my blower motor, the ac circuit board, changed the oil, and more. I am now hoping to get my ac running again because this 100 degree temperature in Houston is killer. Not to mention, only 1 of my windows rolls doen, my car is black, and I work as a window cleaner outside. I am sure my coworkers would be happy if I can get my ac working...lol! Thanks again!

I’ve charged my a/c a couple times. And I refresh my mind when I do it. And this really is the best video I’ve come across. And I like how you re-iterate the Do’s and Don’ts.

Thanks a ton for the video! First timer here - I was able to successfully vacuum and recharge my Truck thanks to this video. I was so happy that I started singing "Hallelujah" when the cold air started coming out of the vents.
The vacuum test gave me confidence that I had put the new condenser back together properly. Thanks again!

Just a quick FYI from a licensed residential HVAC technician, the top port on the vacuum pump is for a normal residential ac hose hook up, not out dated lmao! It’s appears the vacuum pump can do ur home ac or vehicle. A lil late but thought I’d help u guys out with that tidbit 😊

[eugeniojimenez]

To say the least, great video. I have been servicing my vehcile's A/C system for almost ten years, and this young man helped me learn something new. Thank you!

I know that it’s taught about the efficiency of liquid charging, but few people know that it also builds head pressure very quickly, and has, on more than one occasion, damaged compressors, and even blown up discharge hoses. If I’m not being paid by the hour to do it, I am more than content to babysit the damn thing and gas charge, then, there is little to no chance of slugging the compressor. Unless the system is a walk-in cooler or something, the time saved by liquid charging is really not worth the damage it could do. I will say that I have learned some things from this video, however. Keep up the good work of making sure that people out there realize the potential they have to hurt themselves if they don’t do this correctly.

Very well documented process. Did mine today. Thank you!

[gmarkoch]

Followed this guide and purchased the recommended kit on amazon, about two hours after it arrived I had my AC fixed and blowing colder and stronger than I can remember! Thank you for an excellent and helpful video!

Appreciate the video man, went to Harbor freight and picked up everything I needed to get this done. Never leaving my truck for hours at a shop to get this done again!

[johnalbers]

God bless you for this. I have the entire dealership's maintenance and repair manual from GM for my 2003 Chevy Silverado Z71, and 95 percent of it pertains to other trucks. I spent days trying to understand something bigger than an NYC phonebook, and you explained more than it could in all of a few minutes!

The most descriptive demo that I've seen on YouTube in this field. Your expertise is 'spot on'. A pleasure to learn from you. Thank you. LWJ Qld, Australia.

I NEVER like videos or follow someone unless it's just the best information in the world for me. You sir, are the best. You explain soooo thoroughly each step that you answered all my questions. Most people skip the steps they think are obvious and common sense but then other people who are just following steps end up skipping important parts

[madrigal]

Great explanation! simple and helpful information, now let's see how it goes recharging my VW Jetta A/C... crossing fingers...😅🤞 now just need to look for a video showing how to add oil and leak dye...

[wyldmansix]

One of the best instructional videos I've seen yet. Your demo and step by step explanations are perfect for the average person with little to no experience in performing this procedure. You have saved many who watch this, tons of $$$$. Great job! 👍🏼

[tonynash]

Probably the best video I’ve seen for AC work. Thanks
