Heating, Cooling, Plumbing and Air Duct Work: Four Trades at Once

The joke borrows the four elements, water, earth, fire and air, and matches each one to a trade on a four-way split screen.

Earth is a mini excavator digging a trench across a yard while a tech in a grey hoodie watches the cut, the kind of dig a sewer line repair needs. Water is a pair of orange-gloved hands working on a pipe or valve under a cabinet. Air is a bald tech with a red headlamp feeding an air duct cleaning brush into a wall register. Fire is red-gloved hands brazing a line near a cabinet, the torch work behind AC and heat pump installs.
