wire_rubout

There are a few important things that I suggest checking on every service call to reduce callbacks and increase customer satisfaction. One of them that often gets missed is preventing wire rub outs.

One of my area managers and experienced tech Jesse Claerbout shot a video showing the simple step he takes to prevent major damage.

We also just release a new podcast episode today that you can hear in any podcast app or by listening HERE

Cheers!
