I overcharged my A/C compressor with refrigerant! How can I bleed it out to avoid any bigger damages?

My 2010 Honda Accord's A/C wasn't as cold as it used to be, so I went to Walmart and bought a can of A/C Pro refrigerant to recharge it. I follow all of the instructions to the letter, but then realized I overcharged it. The pressure gauge is in the red zone, which isn't good.How can I fix this to avoid damaging my compressor? Will it cost a lot to fix? via /r/cars http://ift.tt/2sqgRjp
