  1. Do you know any Italian that is not a scam ? Somewhere similar to punch and judy pulcinella ?

     

    I like food there but cannot eat anymore because of stupid staff who rush you (bring the bill without asking first, etc...) and idiot totally useless owner who managed nothing but prefer to keep smoking on his terrace, annoying customers.

     

    thank you

    Car AC aircon air conditioning gas refill shops, how do they know that they put enough ? I think they just don't know ! But maybe you know ?

     

    Cheers,

    My car AC has a leak and until I fix it I have o refill few times a year.

    What is funny is that the only real way to know how much gas there is in the system, is to empty it (flush), and then put the amount required.

    When they just refill I wonder how they know what is the total gas in the system.

    For example my car should have 630g, but what they see when they refill is only low and high pressure, not the total gas in the car. Please check the pictures before and after refill, do you think that they refilled enough ? Or it's clearly impossible to know ?

    And what if they put too much ?

     

    I am wondering if any place is actually able to totally empty/flush the gas and refill it with required amount ?

    But how can they know that they inject 630g even when they gauge does not show any quantity ?

    Please tell me what I do not understand ?

     

    Greetings !

    I wish that people do not comment to tell me to fix the leak blablabla... as you can guess I already know it !

    The title of this post is:

    Car AC aircon air conditioning gas refill shops, how do they know that they put enough ? I think they just don't know ! But maybe you know ?

    And this is the only thing that I ask you. If you don't know, please just do not reply.

     

     

     

     

     

     

     

     

    The only way to know how much gas and how much oil is in the system is to empty both and refill gas + oil. Anything else is only estimation.

    You won't find any standard shop that has an idea about what I just said. They all live just as 30 years ago before Internet.
