Electricity in U.S.A. households (and not only there)

The bad thing is that the peak demand when both ACs randomly run at the same time disqualifies me for limited demand rates. Even though demand is recorded by the electric meter, this info was not accessible to first line customer service - they had to refer me to the engineering department to call me back a few days later and tell me the peak demand on my account and determine that switching to demand-limited service might actually cost me more overall with penalties for exceeding the limit.

I have a 200 amp panel with nine open slots out of 40 total.

Since we have buried utilities here, I have no idea what the transformer ratings or homes per transformer are.

If both units are in the attic you could probably implement some really simple relay logic to lock out AC on one unit when it is on on the other...
