We see a little boy playing with toys in a house. He's walking around with a toy in each hand making sound effects. They are perhaps robots in a climatic battle. All around the boy are words floating, moving and spinning in the room. The words are common allergens like: pollen, dust mites, animal dander, bacteria, and fungus. We follow the boy between rooms. There is a woman reading a magazine as well, mom I assume. Finally, we settle on a white vent in the wall. It is slowly sucking in the allergen words. The boy sits on the couch with mom and lies with his head in her lap, still playing with his robot toys. Mom laughs lightly. The room no longer is showing the allergen words, presumably the vent has sucked them all in now and mom and son are safe. Next, there's a shot of the Trane system, it's tucked into the wall, in the laundry room. Finally, there's a shot of the Trane logo with "It's Hard To Stop A Trane" under it, plus trane.com under that.
