A professional technician stands on a step ladder inside a living room, cleaning an opened indoor air conditioning unit mounted on a wall. The technician wears a navy blue uniform, gloves, and a face mask while using a high-pressure cleaning tool connected to a machine on the floor. A blue plastic sheet is attached below the air conditioner to collect runoff water, which drains into a bucket. The room has wooden floors, a sofa, a coffee table with magazines, and houseplants near windows with light curtains, giving a domestic setting.
