03 focus zx3 overheated, weird though?

[03FocusZX3]

Hey guys, so ill try to keep this as short and sweet as possible. My mom was in the hospital for a blood clot in her leg, well when she was discharged she called me to come pick her up, so i was my way (my focus has never overheated in the 3 years ive had it) i told her the wrong floor to get off at, story short i had to drive all around the hospital to find her, well i find her, pick her up and on our way to her house, which is maybe 3 miles away. I pull into her driveway (btw ive had my ac on the whole time) i notice my needle is in the red, im like holy crap, i turn it off real fast, i then look under the hood, i see steam and antifreeze dripping out on the left hose that goes onto the radiator connection, i let it cool down, and ever since then i haven't had any trouble (knock on wood) no leaking, nothing... Im really confused. When i do turn on the ac for the first time that day, the ac compressor will make a clunk and start cooling. Could this off made it overheat. Bad ac compressor?
