I am very weary of taking it somewhere because i know they will tell me "you need a new condenser" or " you need a new compressor" not going down that road. I will do this myselfHello,. 15 mins isn't too bad in my MO, Where I live in South Florida it gets in the mid 90's with a 60-90% humidity.
as far as a A/C check goes, it's a simple task if you have a set of gauges (Amazon sells for 25-50 dollars) and plenty of info on YouTube, otherwise you can always see your local stealership....but be prepared to be told you need to spend $$$ if you go that route....Good Luck !!
