    Determining correct charge on cool days

    Yep I'm a newby, but got a question for you more experienced techs. During this time of year a customer may be using AC one day and heat the next. If you need to check AC charge on a cool day, is there a different process to do this? Or, do you just slap gauges on and look at PT Chart? Also, should superheat and subcool targets be the same when you are so far away from design condition temps? Thanks for any help yall!
