I'm wondering should I get my AC serviced.  I recall a local radiator and AC service place telling me that they should be serviced once a year.  Is that a bit much or should I just drive on until I think there is a problem or it doesn't cool as well.


I understand that the refrigerant in the c-max is different than a conventional car.  Does this mean that any servicing should be left to a dealer?  I see a lot of service it yourself kits at Autozone.  I also heard of some other stuff that you can put into the system to clean it and make the car smell fresh.  Anyone recall what it is?

I don't know the specifics on the CMax but I know the Prius requires a special lubricant oil.  Conventional a/c oil is electrically conductive and will cause big problems if used in the Prius electric a/c compressor.

Do NOT disturb it, if its working leave the AC system alone.  The only time I would do service is after it breaks down.


As far as radiator flush, I have and I haven't in the past, it really doesn't make a whole lot of beans difference.  I think I've done it once on average in my cars.  Never had a radiator problem because I didn't do it enough.   Up to you but I would tend to shy away from that spend the repair money elsewhere.  Alot of those things are just basic revenue generators.

I agree with Raja. Best to leave the AC alone since it is a sealed system. There is no recommendations in to manual for any regular service for the AC. My 2004 Ranger have a very good functioning AC that gets a lot of exercise in the summer and it has never been serviced either.


From what I have heard, it is good to run the AC at least occasionally to make sure the lubricant is circulated but other than that there is nothing that needs to be done.
