I completed a diagnostic on a Rheem A/C. The homeowner advised that the system is just running all day long but not cooling home. I found a dirty air filter. I then checked outside unit and found condenser fan was blowing out a very hot air. The fan blades a low on shaft of motor so they are not functioning. System also low on charge. I did charge the system and then recommended replacement of unit due to age condition and cost of repair.
