I was called to a customer's home to check on a power surge that had caused their air conditioner to stop working. After inspecting the unit, I determined that the power surge had nothing to do with the Freon leak that the customer had been experiencing. I explained to the customer that the power surge had caused a temporary malfunction in the unit, but that it was not a permanent issue. I also offered to perform any necessary repairs or maintenance to ensure that the unit continued to operate properly. The customer was grateful for my help and thanked me for my expertise.
