Inspection of furnace showed that blower was operating properly. 20x25 pre-filter was very clogged preventing airflow. Low airflow caused indoor coil and lineset to freeze up. 20x25x4 main air filter in decent condition. Tested refrigerant pressures. Pressures are spot on with a 18F SH. System is operating in cooling at this time. Keith would like a full system replacement quote to be prepared.
