Last week I had an electrician in to put in some new wiring; I also had an HVAC guy come do the annual maintenance on our system. Since then, the lights in our living room flicker whenever the A/C comes on.
I would usually suspect the start-up capacitor in the compressor, but the compressor is on a separate panel from our living room lights. On the other hand the 1st floor lights (1) and the attic air handler (4-6) are on the same panel, as is the new wiring, which was added to the Bath GFCI circuit (2) as shown here:
The new wiring is supporting our basement de-humidifier and a desktop computer. I confess to knowing next to nothing about home electrical -- is it possible that the additional current being drawn by circuit 2 could be causing the flickering of lights in circuit 1 whenever the HVAC kicks on?
