My 2010 Surbaru only has a blue 'H' cap. Does this mean high pressure and I need a Subaru technician to service it?

    No if the cap has H you are looking at the high pressure port. You can't connect to this port, the ac recharge kit connection won't even fit.

    Find the port that has L on it. All Subarus have it, you just need to figure it out.
