El Camino cool?

Hello Back again with my 82 camino. I've replaced most ac parts except for condenser and hoses, since last summer. Air cooling about 60% mid May, no leaks found, took 1 lb freon. Took another lb. today, June 15th - no leak found again. Seems like a serious loss not to get a whiff on detecters! Sure could use some help. Thanks-sixes

WHOOOOOOOOooooooooooA Nelley! STOP!

A/C is not DIY repair unless you have ALL the proper tools for repair. That includes a gauge set, which tells you what's going on with your system.

Also, unless you have an AC license, it is illegal to charge your own AC system.

Not to preach, but you have to know what you're doing here!

Joe- Gave you the wrong impression here. This was two different professional mech. a month apart. That's why I'm turning to you again, (this $60 freon top off every month will get old quick) Thanks again

Is it being charged with R12 or R134A? If it's R134A, throw all the old parts out that are R12 related and start with all new stuff. R134A is higher pressure. Old tired parts, especially on a conversion, have no place in a R134A system.

Ummm, I have a problem with guys that are not checking for leaks before they charge up. You have either a leak or something amiss here (maybe a stuck orifice tube). Either way, only so much refrigerant goes into the system. Overcharging it is not good.

Go back to the first guy and ask him why his charge leaked out so fast. Have him redo it free.

Joe, thanks for replying. The whole ac system is updated. Both mech. checked before & after freon for leaks, with different sensors. Not a peep! I'll have the orifice checked. thanks for being around.

The most difficult section of an a/c system to check is the evaporator. And due the labor required, usually the very last thing to ever get changed out. Sounds like this MAY be the case..
Are these guys using any kind of dye to check the system? If not, sounds like they need to...

If you've lost a lb in 2 months if I'm reading right a good A/C tech should have no problem finding the leak. You should look in the Yellow pages and take it to a shop that only does automotive A/C they are the true pro's..

msargent is correct in the evaporator leak. I always stick the leak detector down the ducts and if you are leaking at the rate your system is and they have a quality leak detector they should find it.

Thanks everyone, I should have tried the expert ac man first I guess. That's my next step. I'll let you know what he finds. Thanks again! sixes
