No cooling call. Found filter up in coil collapsed and coil wearing a fur coat. Coil was much worse than pics show. I already brushed out half of it before taking pics. Cleaning coil out and testing system. Now air can get through system and cool like it should. Have your system cleaned at least 1 time every 2 years. Your efficiency will stay up and not fall. When it falls your utility bills go up. Very important that this is done. It also protects your compressor from going bad due to system airflow. Unchanged dirty Filters and dirty coils are the #1 reason compressors fail in USA. Call us for your maintenance today.
