Upon arrival found master bedroom unit not cooling. Found that the disconnect was busted and needing replacement. Found that the capacitor for condenser had bulged up and went out. Replaced 45/5 capacitor and compressor and fan motor came on. Checked pressures and found system a little low. Homeowner wanted to move forward with the repairs. Replaced disconnect, the capacitor and added two pounds of R-22. System is now cooling properly.
