Typical work includes checking refrigerant levels, cleaning or replacing filters, testing airflow through ducts, inspecting ignition and burner components on furnaces, and setting up programmable thermostats. Emergency calls cover systems that have stopped running, while tune-ups address wear before it becomes a larger failure.
