Ice buildup on your outdoor unit in Concord is often caused by issues like low refrigerant levels, a dirty evaporator coil, or restricted airflow. This not only reduces cooling efficiency but can lead to compressor failure. Our technicians at Climate Shield perform a thorough diagnosis to pinpoint the exact cause, then provide the necessary repair—such as sealing leaks and recharging refrigerant, or cleaning coils and checking ductwork—to restore proper operation and prevent future ice formation.
