A/C systems are awesome. Almost like magic. It's amazing to me that a 44 year old refrigerator in my house can still be working and never need the addition of freon. Simply amazing. Great video and great explanation, as usual. Thank you!

A very comprehensive video explanation of a complicated process. Thanks for making this understandable for us non- engineers.

Ten seconds in and you already got my subscription, that is a gorgeous audio setup! I hope you made a video on it cause that'll be next! Going into this video with basically zero knowledge on AC. I'll eventually be putting a setup in my 72 gmc vandura. Hopefully sooner rather than later cause I live where it can get into the 120s haha

Great video and really appreciate your big effort on making this video on here. I've got bits and pieces wanting to build a custom system just like you have on one of my vintage projects, I have ac tools for recharge vacuum pump, but I never went to building from scratch but am confident after your explanation thank you

Good video with lots of educational value.

I like to think of the "magic" happening at the transitions. High pressure to Low, Low Pressure to high. You said that. lol But I like to remember that part. Low to High makes heat. High to low makes cold. Pretty sure of that. Hahah! Great work here.

Nice work, very detailed. A re-engineered Jaguar from head to tail will be a conversation piece for many, many years. Chip Foose does good work but he has a dozen experts working for him. Wonder if he could do all this by his self like you are?? Great video on this part, now waiting for the killer stereo and interior episode😉 Thanks for all the hard work in front of and behind the camera.

I enjoyed the video. Your dedication to complete the process and captute the video to share are appreciated. The car really turned out nicely and I hope you are still driving it when your 60.

I don't know what your local ambient temperature is but 38ºF seems a little cold for the output (usually an indication of too little refrigerant). Also your controls should keep it from getting that close to freezing, otherwise your core (evaporator) will freeze up.

Could you have used a Camaro condenser on the engine and avoided a custom connection? Or was it easier using a Yukon condenser with the pcm?

[dougaustintx]

Surprised you mounted the txv in the engine compartment, rather than inside the car's cabin. Gets really hot in the engine compartment.

I'm bummed that you received a compressor that didn't have the lubricant in it! I presume there's no way to ascertain beforehand whether the compressor has oil in it or not. That sounds...perverse... I'm glad you overcame, though. You did a beautiful job! 👍

[pglick]

I don't need it, but you should know that the "better video" for adding refrigerant is not available.
