Also there was kinda a burning smell, could it be that the compressor's clutch seized and the belt's slipping? Does getting the system charged put added stress on the compressor?
Wow. And I'm assuming you've asked Midas about this? Did they say this was normal?
I've had hit and miss experiences with Midas. West side Bloomington Midas - the manager there is an absolute dick. South side Bloomington, they're fantastic. *sigh*
It sounds very
much like Midas over-charged your system with too much refrigerant. Too little freon and it won't work. Too much freon and it won't work AND could eventually ruin your compressor AND/OR your belts! That squealing you hear - that's your belt slipping cuz the compressor is being slugged with too much liquid freon! Turn your AC on, pop the hood and see if your compressor pulley is turning or digging in it's heels while the belt just smokes.
Take it back and have them look at it. And watch them. If you find they put too much charge in, I'd make `em replace your belts for free.
Of course, you could have a problem with your belts not being tight enough/worn or your compressor going out. If your system has the proper amount of charge in it and it's not overcharged - then yes your compressor is bad and it may very well cause your belts to slip and smoke.
