EXISTING...
3,600 sq-ft = 10,800W
range 15,000
dishwasher 1,500
fridge 1,500
disposal 600
laundry 1,500
dryer 5,500
water heater 5,600
---------------------------
40,500W

(40,500-10,000)*0.4 = 12,200 + 10,000 = 22,200 (add 2 AC = 32,200W /
240 = 134amp

NOW ADD...
2nd refrig 1,500W
2nd disposal 600
2nd oven 1,500
leave some spare capacity for eventually adding a hot tub at
& the 8" jointer I want to get for my woodworking shop (208V @ 20A)

Looks like upgrading to 200A for the new, added appliances is probably

You're welcome.
