So it looks like I'm going to have to start getting rid of some of my ASICs, underclock my FrankenJups even more or look for datacenter hosting... unless someone has some other helpful tips that don't involve me adding more electrical service to my house.
Maybe you know this already, but remember that the electrical load is being spread between two conductors to the home. If you manage to put 100 amps on one conductor, the breaker will trip even if the other conductor only has 50. You've got quite a bit there (especially the AC), but you may be able to rearrange things so that the breaker doesn't trip (move some of the miners to a different circuit either by plugging them in somewhere else or swapping a breaker or two in the panel so that the load is on the other conductor). If you've got a clamp meter, it'd be handy.
I have miners in virtually every room of the house so they're spread out pretty well. I honestly couldn't tell you if they are spread evenly between the 2 conductors though. I've never actually heard that before and don't know how to check. Using the 30 amp dryer circuit has helped stop individual circuits from tripping though. And I have a lot of watts running through that circuit alone now.
Maybe "borrow" power from your neighbors

Take the cover off the breaker panel,use a clamp amp meter on the two main legs feeding the breaker panel.the "neutral" may go to a small "rack" on either side in the panel with all the white wires connected to it,do not measure that one.
DO NOT TOUCH ANYTHING in the panel,just clamp on to the cable somewhere & you'll see how much each leg is pulling
