I was called to a home to repair a faulty air conditioner. Upon arrival, I found that the capacitor had failed, causing the system to malfunction. I replaced the capacitor and tested the system to ensure it was working properly. I also checked the refrigerant levels and added more if necessary. Finally, I cleaned the condenser coils and checked the electrical connections to ensure they were secure. The customer was very satisfied with the work and thanked me for my prompt and efficient service.
