Breaker box in new home: 40 to 60 = expensive?

Just had some air con guys come over our home and estimate installation costs. We will have about 6 or 7 air cons in our home (it’s big). They said if we decide to turn them all on at once, or even close, it will for sure trip the breaker.

If so and we want to make it work we should call the electric company to come out and change the breaker box specs from 40 to 60. I get that the house needs more juice in that case. Air cons + water heater + tea kettle + TV + hair dryer…..will for sure pop something sometime.

What I don’t know is associated costs with asking the electric company to upgrade said breaker box. For example, if we use the same devices as we use now, will having a more powerful breaker box automatically up the electric bill? I assume it just ups the capacity of the home’s appliances.

Thoughts? Experience? Thanks!
