air conditioner recondition/recharge?

Your car is 10 years old.
Some minor coolant loss might be expected.
Also expected is some dirt accumulation in the condensor/evaporator fins.
And maybe some compressor wear too.

Just blindly throwing some coolant at it is seldom a good choice.
A leak test and inspection by a professional would be much better.

 

prius a/c is high voltage electric with specialty oil. take it to a dealer, or known quality hybrid a/c shop. don't take anything for granted, wrong choices can cost thousands.
@lech auto air conditionin is an expert

 

If you don’t have the equipment to completely drain it out put it under a vacuum and weigh it in pretty accurately then hopefully take it somewhere where it can be done correctly.

Topping off can be a very very very expensive mistake.

it works for some people sometimes and they are very happy but for the ones that doesn’t work for their bank account is about to take a big hit on a repair bill.

like Clint Eastwood said in his movie(“ do you feel lucky“)
