Hello some help would be much appreciated.
I get these loud squeel or squeek on cold starts about 5-8 sec shorter when it's less cold.
Serpentine belt? AC?

Subaru Legacy 2011 2.5i

Definitely an aux belt squeel. Will either need tightened or replaced usually. You can spray a small amount of WD40 on one of them to see if it stops the noise to help figure out which it is, although the alternator belt does look a touch loose.

Wouldn't be surprised if they were original belts though, wouldn't hurt to change them at some point to prevent you being left stranded from a broken belt. Check the cambelt history too for that matter.

Great! Cant find any history of it being replaced gonna order one and replace as it's cheap enough. Worst case maybe the ac pulley hopefully don't need to change the whole compressor.
 
AC pulley looks to be ok, the compressor isn't turning so the clutch is released ok. It's possible the bearings are tight on the pulley itself though but not likely.
 
Think I've found it sprayed some water on it before starting and it stopped for a few seconds.
Alternator belt as I think this car doesn't have a steering wheel pump.

On the longest run of the belt, you should be able to twist it quarter of a turn. That should get you pretty close on tightness.
