Info in previous responses is all potentially relevant, but ...

Suggest you take the time to learn about basic home circuit
design and amperage loads. Then inventory elec. devices you
presently use (and their max amp draws) and predict any that
you might want to add in the coming years. Object is to
estimate max house amperage (100, 125, 150, 200) -and-
number of circuits needed in new service box.

I don't have a handy reference to home circuitry, but it's not
rocket science by a long shot. Maybe someone else can suggest
a suitable info source.

Cheers,

Hi

I've decided to install central HVAC and was told that I will need a new
panel since mine is a 60 amp. My home was built in 1951. I have upgraded to
all modern appliances and have added numerous lighting and ceiling fans
also. I also have a game room with about twelve coin operated commercial
arcade games. Currently there is only a gas wall heater.

Since I have to upgrade the panel what amperage should I need and what
should I expect to pay. Should there be a difference in price between a 100
and 200 amp service. Also should the upgrade entail upgrading two prong
outlets, the ones without the ground. Since I have had many electrical wire
upgrades in the past all new circuits have grounds but the
bedroom/livingroom still have two prong plugs.

Thanks.
