Tonight the USRFD was dispatched to a home for smoke coming from an air conditioning unit. Chief 1230, Engine 1232 (OIC Capt Sklar) and Tanker 1233 (OIC Ex-Chief Levine) responded to find an air conditioning unit malfunctioning causing the air filter to catch fire. Crews disconnected the air conditioning unit, overhauled the burnt filter, and the home was naturally ventilated. Once the smoke was cleared, all units cleared.
