AC tripping in extreme heat...need suggestions!

I had a similar problem on my old MH. Unit would draw more current on hot days. I got a gallon of coil cleaning fluid from commercial AC supply store diluted it as directed and used a garden sprayer. Got on the roof removed the Cover and soaked the coils then flushed with fresh water. You would be suprised all the junk that came out of the coils. Used shop back to suck up excess water and junk. AC worked much better after that.
