Scott:
Did the poco change/upgrade the drop from the pole?? Did/is the poco "upgrading" the transformer??
Are all the connections good??? (neutral too)
If the HVAC units are in fact 50 amps each, that is 50% of the 100 amp feed to each unit, correct? Did the installer of the new service do the proper calcs to make sure it's sized right???
Lastly, ask the HVAC guy about a "hard start" kit (capacitors), I used that a few times to "reduce the dimming/dip"
