I found a guy who wants to charge me 300 for the a/c system for my coupe is that too much it's everything from the firewall inside the engine bay nothing from firewall inside that cabin is that a good deal or not

 

People throw civic a/c systems in the garbage, keep looking.

 

way too much - about $100 is fair.

if it were all - under dash, engine bay and all harnesses and relays, then it may be worth it.

 

Is everything in working condition?

Be very carefull buying, if it wasn't taken out and stored properly you could run into issues trying to get it to work.

I would go visit a junkyard. Try to find the ones that has rear end damage, and pick it off like that. They should be like $100-$150. I'm glad people still enjoy the luxury of A/C in their Civics and not take it out for funsies cuz it saves weight and makes your whatever D, B series pull harder.
