Just clean the evaporator every year or so.
Service for a/c???
I wonder how should I maintain service for the a/c. It does not say anything in the User's manual. What should I do to the a/c, so it can last longer in regular use?

You should do a little more than that.Make sure the evap drain is free of debris and lets water out,also you should replace the cabin filter and if health is a concaern replace it with a carbon one(healthwiseautofilter.com),have been useing at my shop for a while.Check them out.

The cabin filter isn't an A/C maintenance item. Your carbon filter advertisement posts really suck.

well i do believe the cabin filter is part of the heater /ac system.and if the drain plugs ,you can clean the evaporator all you want it still won't clean the drain.Carbon filters don't even compare to standard ones and the health benifits speak for themselves.
If the cabin filter gets plugged it restricts air flow that can cause the ac syatem to not function properly so if thats not ac maint. i don't know what is. But thanks for the comments and it's not an advertisement its a product that i install in my shop and it works great,so i will tell others about it or forums not about advise.
I have a question ?. Are you a tech?>

Does this list on the service maintainance list or do I need to tell the service dept to do it?Just clean the evaporator every year or so.
Cabin filters are on the list .but i would ask them to check the filter anyway.
How do I know cooling refrigerant need to be refilled? How long should the original cooling refrigerant last normally?
until the a/c doesnt work anymore
chill TRD....the guys just pitching a suggestion for a carbon filter...
but for my a/c system all i do is use a cleaning solution foam my dealer has to clean out the evaporator box, spray some disinfectant that comes with the kit into the cowl to kill bacteria in the system, and i change my cabin filter twice a year...pretty simple maintenence, and its easy to do and cheap as well

niceguy: Cleaning the evaportor core isn't listed in the factory maintenance manual. Some dealers do include it in their regular maintenance. You will need to check with your particular dealer. It should only cost around $30-$50 to have them do it. Cleaning the evaporator will do several things:
1) Keeps mold and mildew off of the core making it work more efficiently
2) Keeps mold and mildew off of the core so that your A/C doesn't smell like an ass or a shoe
3) Keeps the tray and drain clear of dirt, dust, mold and mildew, as well as clean the drain itself. The cleaner is actually injected through the drain itself (apparently healthman doesn't know that) as well as a deoderizer through the HVAC air intake (at the cowl).
4) Keeps mold and mildew from retaining moisture longer which can accelerate corrosion.
If the A/C is blowing cold air, don't mess with the R134-A. No other maintenance is needed.
healthman: Nope, I'm not a Technician.
CorCamrySE: Hell, you even deleted one of healthman's cabin filter posts because that's all he does is pitch them in every thread that he can think of.

generaly cleaning through the drain does not cover the complete evaporator but if you do it that way the drain should be clear.But i guess trd vvti didn't know the cabin filter is part of the a/c system.And bye the way trd vvti I am a tech.Hope every ones up to date on a/c systems.
yeah TRD thats the stuff im talking about
its a foam that comes with a tube an d adapter to force the foam into the condensor box and clean it out, and once the tube is removed the dirty foam drains out the drain tube underneith the car, and the spray is sprayed into the cowl while the car is unning with the fresh air a/c on full blast
all dealers offer this service....when i get a chance ill take a pic of the kit, and maybe do a DIY when i do the service to my car before i get into a/c weather

corCamry se does the foam smell at all or leave a residue
it leaves no residue, but it does leave the smell of a mild household cleaner (ie windex etc) for a short while. it doesnt smell bad, but rather, it smells clean
Actually, the cleaner expands and completely engulfs the evaporator core and the evaporator case. Even a plugged drain gets cleared by installation of the cleaner. Of course when the cleaner and contaminants run out, it also helps to clean the drain.generaly cleaning through the drain does not cover the complete evaporator but if you do it that way the drain should be clear.
Obviously, you don't know what your talking about.
Actually, it's not an A/C filter as many people call it. It's a cabin air filter. It filters air that enters the cabin. Actually, it's not part of the A/C system. Are the cowl vents considered an A/C system part because air enters there? No, they're not. Is there a seperate filter for the heater? No.But i guess trd vvti didn't know the cabin filter is part of the a/c system.And bye the way trd vvti I am a tech.Hope every ones up to date on a/c systems.
You're probably not a Technician either, otherwise you'd know better. I'm guessing that you're simply a mechanic.
I hope that you are now a little more up to date on A/C systems. It appears as if you're the only one in this thread that thinks he is, but really isn't.
I probably get more phone calls per day from across the country seeking automotive technical advice, than you actually perform repairs.
Go hug a carbon A/C filter...
If you only do ONe thing to the a/c, the right answer is to maintain the A/C just USE IT. Thats all you REALLY have to do - use it AT LEAST every two weeks, turn it on for at least twenty seconds (so says toyota).
you know the couple ounces of special oil that gets dumped in with the refrigerant, well this oil is what keeps the bearings and seals from drying out and wearing out. The only time the refrigerant oil circulates is if you run the air conditioning. (Yes, even in the winter you should do it - the car's cold in the morning anyway right).
If you go too long a time, like in the winter, without turning on the air - guess what, your air might not work cause the seals and bearings are dried out and no good anymore. On my Dad's old 1982 Dodge Mirada 318, the A/c belt snapped when he went to turn it on. The compressor had seized because he didnt use it for a long time.
So just use the A/C every two weeks, or better yet every week, and the a/c will last you the longest. And refrigerant doesnt wear out so it doesnt need to be changed ever. (I have a type I II and III refrigerant handlers license and a little knowledge of this stuff). the only time refrigerant gets serviced is when the air quits working and the tech goes in to fix something else and has to open the system.

when you look up cabin filter it usually falls in the heating/ac system on most repair data.so i guess it is in the system.Look i'm not here to argue just add advise but atleast i am stiil open to learn new things.
marc780 your air con would get a work out if you were living in Adelaide Australia today was their first day under 37 degres centigrade for 14 days straight so i think they manged to use it at least every two weeks (MINUTES) lol
Do you mean if we use the a/c correctly, it will not need service or refill refrigerant, and it should as cool as new even after 10 years?If you only do ONe thing to the a/c, the right answer is to maintain the A/C just USE IT. Thats all you REALLY have to do - use it AT LEAST every two weeks, turn it on for at least twenty seconds (so says toyota).
