It's very possible that the didn't vacuum out the old coolant before he filled it up with fresh. If there's any air left in there, it's not gonna cool rite.

Don't get your nickers in a knot....yet.

Probably something simple like a blown fuse or something. Go and talk to them calmly and let them have a look at it before you get all worked up.

it sounds like the air conditioning system needs to be charged back up

Try to consult the mechanic b4 sue them. BTW, you should have your own renowned mechanic.

sounds like the right plan to me.
