I was called to a home to perform a furnace maintenance check. The customer reported that their furnace was not producing heat. I arrived at the home and performed a thorough inspection of the furnace. I found that the blower capacitor was faulty and needed to be replaced. I removed the old capacitor and replaced it with a new one. After replacing the capacitor, I tested the furnace to ensure that it was working properly. The customer was happy with the service and thanked me for my help.
