I serviced two Carrier air conditioners in Youngtown, AZ, ensuring they're primed for the peak season. I began by inspecting the coolant levels to maintain optimal operating temperatures and prevent system overload. The condenser coils were thoroughly cleaned to enhance efficiency and airflow. I also checked the electrical components, securing all connections and testing capacitors for reliability. Air filters were replaced to promote better air quality and flow. After a complete cycle test to verify functionality, both units are now running smoothly, ready to deliver reliable cooling during the upcoming hot months.
