Cost to replace entire ac system?

Hey i bought a g35 coupe that a guy planned on tracking but never got around to. Long story short he got rid of all of the ac components in the engine bay including cutting the ac lines going through the firewall. How much would it cost me to get all the parts to rebuild the ac system?

It's impossible to just guess a number. You need

-line set
-compressor housing
-compressor drive belt +possibly the tensioner pulley
-couple miscellaneous o-rings
-condensor

My guess would be as low as $200 (if you found a car in salvage and ripped everything you need) and as high as $900 if you have to buy everything new.

If you know how to charge the system yourself and have access to refrigerant then

-R134a and oil (do NOT try to charge the system with a bunch of cans of ACPro or you're going to be buying a second compressor...)
-manifold
-vac pump
-nitrogen to check for leaks

If not then you can basically throw on $500 for parts/labor to have a shop test for leaks and charge the system.

If you're paying for a complete install throw on an additional $1000 labor to have the stuff installed.

These are just wild guesses as numbers. You need to shop the parts and labor yourself.

You can do everything up to the refrigerant charge yourself and definitely save a ton of money, it's not hard to nitro test leaks on an AC system and there's no special license for nitrogen.

To get your hands on the R134a however you need to pass the EPA section 609 test, then it's as simple as going to a local refrigeration supply house that will sell to private licensed individuals (as opposed to the ones that will only sell to account holders).

If you have the system leak tested and already pulled vacuum so it was literally just waiting for refrigerant you might be able to get it charged for cost + 1 hour labor. Cost is only like $20 worth of actual refrigerant plus about $5 of oil, 1 hour labor is usually $125.
