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.
