Why HVAC Techs Are Always Tired: Camera, Excavator, Sewer Trench

A tech with hair tied in a bun, a black cap and a black hoodie kneels near the house, running a drain camera into the line.

A mini excavator then cuts a trench across the front yard while two techs in red gloves work the edges with a shovel and a digging bar.

The last shot is down in the trench, where a tech stands beside the exposed sewer pipe and its cleanout. The camera run is what tells a crew where to dig and how deep, so the trench lands on the problem instead of wandering across the lawn.
