Running late and reschedule texts for home-service techs

Hi [first name], [tech] here. I'm running about [X] minutes behind because [short honest reason]. New arrival is around [time]. If that doesn't work, reply and we'll find another time. Sorry for the wait.

Tip: Send as soon as you know, before the arrival window starts. Give a specific time, not "soon."

Hi [name], I'm running about [20] minutes behind. Still coming today. New ETA around [time]. Sorry for the wait.

Tip: If you're going to miss the window entirely, say so and offer a new slot.

Hi [first name], I'm sorry, but we need to move your [day] appointment because [reason, e.g. "our tech is out sick" / "storms are forecast all day"]. Could either of these work instead?
1) [slot]
2) [slot]
Thanks for understanding.

Tip: Always offer two specific times. It's faster than asking when they're free.

No problem, [first name]. Here are the next openings: [slot 1], [slot 2], [slot 3]. Which works best?
