Hello fellow members, I've been a long time Mustang fan, but this is my first post so please bear with me. I have a 2001 Mustang GT mostly stock.
So let me start from the beginning, like the title says I'm having A/C problems. I recently took my car in to the shop to get a refill on refrigerant. Last year it was blowing hot air on full blast so I recharged it myself. This year I had the same issue again so I decided to take it in to see if there was a leak somewhere. The mechanic said the schrader valves were bad because when he removed the caps they were wet and that was causing the leak. He replaced the valves then recharged the A/C and tested it out.
Then another problem came up. He showed me that while my car was idling with the A/C on full blast the pressure on the high side was hovering around 250 psi. Then when he would rev the engine up to about 2000 rpm the pressure would jump up to 350 or 450 psi, I can't remember which exact number.
He said the A/C condenser was dirty and/or clogged from the inside. He also said that my car has a certain type of filter about half the size of a no. 2 pencil and that could also be clogged and needed replacement. He gave me an estimate of $160 to clean up the condenser and replace that filter.
My car currently has 140,000 miles on it and i don't think i have ever messed with the condenser so I'm pretty sure its dirty on the outside. I also noticed slight damage to the fins on the front, about the size of a thumb print impression. My question is, is this guy full of it? Or can he be trusted? Thanks for the help.
