Yes, ice buildup on your outdoor unit is a sign of a problem, commonly due to low refrigerant levels or restricted airflow. Running the system in this state can cause further damage. We recommend turning the AC off at the thermostat to let the ice melt. Then, contact LTK. Our technicians can diagnose the root cause—whether it's a leak, dirty filter, or failing component—and perform the necessary repair to prevent future issues.
