Network techs don't do home calls, he won't be the right sort.
Proving out the RF network is easy enough, just check CMTS for issues from other modems in the postcode on the same equipment.
A more relevant question would be to work out why this happened:
Power Level (dBmV) 0.55 -0.18 0.29 0.51
Power Level (dBmV) 6.10 5.72 5.95 5.96
Both levels are fine, an unexplained swing like that is not, though it is an almost exactly 6dBmV swing and upstream power dropped by 0.5dBmV - consistent with removal of a 6dB forward path attenuator, the 0.5dBmV upstream change being insertion loss on the attenuator. If you removed an attenuator put it back and your power levels are nigh on perfect.
