Evaluation on 2012 carrier heat pump zone system obvious smell of burnt electrical in home. Opened air handler and checked all componenets pulled blower motor inspected motor and heat strips. The system is terribly corroded and has water damage some of the zoning Componenets are inaccessible due to limited attic access. Due to age and condition would strongly recommend system up grade. Customer is planning to sell the home in the next few months. Will follow up with customer tomorrow 10 to 12 PM
