Air conditioner over heating wont cool fixed 7708754113

This air conditioner was over heating and shutting down from high pressure. The psi was 85/600 it would only come on for a few minutes before shutting down. We had to use a strong acid wash to get the dirt off it so it could stay on long enough to cool the house. After acid the?psi was 75/250. A wash without acid would not help. The acid foams up when it is working. The owner doesn't have to buy an air conditioner today. It was cooling great but who know how long it will last after years of abuse.
