My air conditioning temp got considerably worse after having it recharged at the hobby shop on base where I live. It used to come out at maybe 55 degrees F, now it's consistently pushing out barely chilly air at 75 degrees F. Any advice on how to fix this? Vehicle is a 93 Civic Hatchback CX

 

Overcharged!

 

So basically flushing it, & filling it with the proper amount of R134a refrigerant would fix that? Great, simple. Thank you

 

Post the high and low pressures.

 

Before you do anything, go back to the shop and tell them the problem. They should fix it for you.

 

If its a 93 and it came with R12 and the shop replaced it with R134A then it efficiency will be terrible. Plus the oils and refrigerant itself does not mix between R12 and R134A.

 

I agree about the 134 in a 93...who recharged it? Usually the post shops are diy. So you will need to get a few new parts and convert it to 134 properly.
