This summer hear is kicking my ass. 1986 jdm factory 4age. The ac in mine works kinda okay but it's very mild. I think all the ac components are original but I can say for sure the compressor kicks on based on the rpms dropping and hearing switches/relays kick on when it blows coldish air. Would I be able to get away with having a shop recharge the refrigerant with new freon? Definitely trying to avoid replacing ac parts. Thanks
