Sent our commercial HVAC technician to a property in Lawndale, CA, to address a lack of airflow reported from the A/C. Upon arrival, he found the unit iced up due to a badly clogged filter. Turned unit off except for the blower motor while he went to obtain correct sized new filters from the local warehouse. Returned to find the ice properly melted. Old filters were swapped out, new filters dated. Unit running properly now, no other issues to report.
