I searched for some previous threads about this but they all involved the compressor failing. I hit an animal that dented my condenser. I noticed some green moisture but it never dripped or puddled. I checked this after it happened and continually for months after and I never saw any evidence on the ground of leakage. The A/C worked all summer. Well winter went and summer is back and now I have no A/C. Obliously it had a teeny leak so i need to replace the Condenser. I know there is a little bit of R134a left as on not so hot days its cold. just the hot ones it cant keep up. So as soon as i break the seal will I need to change the dryer as well? I was hoping this would be fairly straight forward. Im I missing a bunch of things/steps? I do not have a lot of experience with AC as this is why I'm asking. I know when I am done, the system will need to be vaccumed out and recharged which I will have done by a professional.

thanks

Definitely change the dryer. The drier is filled with "silica jell beads" same as that stuff you see in little packets when you get a new pair of shoes... that says "do not eat". It absorbs moisture until it is fully saturated, there is no way to tell how much life is left in it so anytime you open the system it is best to change the drier. Moisture left to circulate in the system is not good for the compressor.
Being they are usually cheap, I would change out the orifice tube also just to ensure maximum efficiency; they have screens that can get clogged.

My company designs and builds A/C units for Cranes, Ambulances, RV's, Buses etc. :cool2:

Thanks for the Help. It looks like the Dryer is actually attached to the condenser. I will have to check to see if it has all the parts I need to do the job.

so i see the desiccant bag and filter are inside of the drier that is attached to the condenser. Where is the Orifice tube located?

My information on HVAC is cataloged by processes as opposed to parts. (And I am ignorant when it comes to ACs) What process relates to the Orifice Tube? Could it have a different name?

I'm not entirely sure if the CTS has an orifice tube or TXV... If its orifice tube I'd definitely replace it... If its TXV I wouldn't worry about pulling the dash to replace it since you didn't have a compressor failure... If the receiver/drier is attached to the condenser then it simplifies things and that's one less part to get... I would replace the condenser, receiver/drier if separate, add a few ounces of oil, vacuum and recharge...
