Default draining and removing air conditioner - a/c

I never use my a/c and I’m going to remove it. I know it’s against the law to remove the Freon so I’ll pay someone to drain it. I checked courtesyparts for a few diagrams and figured I would wing-it but I’d rather follow a guide instead. Can someone point me to a good DIY?

Don't remove your A/C. I did it before with my old Mustang, hardly worth it at all. And it made it harder for me to sell the car

Sorry, I forgot to mention that my Z is my track vehicle. I don't daily it and don't plan on selling (for another 6-10 years).

Its pretty self explanatory. The compressor and condenser are bolted in and buried. Be prepared to take everything off in the front to get the condenser off. It should help with airflow to the rad I suppose. The lines are probably more trouble then their worth to shed half a pound. The evaporator if its like most vehicles will make you want to kill your mother since most of the dash has to come out. That probably isn't worth it either. Id focus on the compressor and condenser and cap off any electrical connections to prevent corrosion and any future problems.

I pulled the compressor and used a dead pulley in it's place. Pulled the condensor and cut the lines out to make the job easier. The evaporator I left alone.

You don't have Freon in your A/C. You have R-134A refrigerant which is environmentally friendly.

I disagree with this statement. The gas is still commonly referred to as freon, and it is safer to the atmosphere than the old gas called R-12. People used to release R-12 into the atmosphere until they discovered the harm that it causes, so now R-134A is used. BUT! the 134 should still be collected with proper A/C recovery machines and should still NOT released into the atmosphere.

Good advice. After looking it over at courtesyparts and googling some stuff, I understand the amount of work involved with removing everything. I may just remove the compress and condenser. I'll probably have to snip some lines (rubber/metal) that are leading into the compartment. It's ok to just cap everything off, right?

Is that a fact? I spoke to a 'mobile mechanic' and asked if he can remove freon from my vehicle. He told me that it's a $50K fine to remove it anywhere other than a shop (I suppose it's a Virginia law). If R-134A is safe then does that mean I can drain the system myself?

The freon in your a/c systems must be recovered with the proper machine at the garage and not released into the atmosphere.

R134 is still illegal to knowingly vent to atmosphere, as per the clean air act...

I did it, cause global warming is BS. Its freaking 20 some degrees here today and its almost april

I deleted my A/C (also a track car), but had to leave the gutted compressor housing on the block because the TN kit uses it as a mounting point. However, you dont need to leave a pulley and run a belt to it. Heres my setup:

here you can see the leftover housing and the new belt route:

It's the gas in your A/C system.

I personally feel silly when I read that kind of threads, lol I didn't understand almost anything except first comments. Guys, I guess, you are more smart in all these stuff, can you suggest me the best aircon repairing service(speaking of airons). I've just managed to discover really highly-rated servicing(www.socool.sg/) , but I still have some doubts. Could you suggest anything? My aircon is seeping all the time and this oily water seems to be not ok.
