Hard to point you in a direction.
Can you measure the voltage at the panel? What is it? What is it when the
a/c starts?
I would do this before you call the utility. They will be not surprisingly
SLOW to respond to something vague like this.

Other poster have suggested that checking the connections in the panel would
be a good idea. I concur.

Was the panel changed/moved for the remodel? Was any work done near the
grounding of the panel? Water/gas bond still connected? Is the ground still
connected?

If your the only load on the transformer then MAYBE it is unique to your
home. Odds are it is on your side.

Normally, when you have this, dimming when the AC comes on, the lights that
are dimming are on a loose neutral.

Are those lights on the same circuit as the A/C? If your a/c was
drawing unusually high current I would expect occasional breaker trips.
Anything that does not trip the breaker should be suppliable by the
transformer. I would call power company. Also high chance of loose
connection, which is dangerous.

This is Turtle.

In this age and time , anything is possible.

Check the voltage at the service pannel and if you see this dip in the voltage
there. Call the power company. If you don't see any dip in the voltage at the
pannel . You have a problem inside your house. call a electricial to come fix
it.

The Cheapest might be to call the power company and let them see as to the low
volage when the A/C comes on. If there is a drop of voltage at the meter pan.
It's their problem. If not , it's your to fix inside your house.
