AC tripping in extreme heat...need suggestions!

Thanks everyone. I did clean out both units. I didn't use a hose but brushed and vacuumed both coils and they were very dirty. It still tripped. Should I try using water? Could I have missed enough dirt for it to still have trouble? The condenser coils didn't look too badly bent but I only saw one side as the other had the shroud and fan in front of it and couldn't imagine how that side could get messed up.
