my car got hit by a dear here the problem after i drove back home

when i start up the engine it sound normal but when turn on AC it sould louder the AC make squeek noise for few sec then stop, so i turn off AC the engine sound normal but i still hear the AC noise again for few sec ... is it anything to do with the belt compressor or any?

if the belt is too loose or contaminated with fluid(leak)it will squeal when the ac is turned on due to the extra load.
