We arrived to check west side system that was not cooling at this facility in Pompano beach. We found that evaporator coil was frozen solid due to no airflow. Found that evaporator blower motor is bad and needs to be replaced. Motor could have gone bad due to lack of airflow which caused motor to heat up. Both evaporator coil and blower wheel have been quoted for cleanings due to being extremely dirty and causing lack of airflow which could have damaged blower motor.
