AVG Cost for electrical panel upgrade 100 to 200 amps

[Tamika Howard]

Hi,

I have an older 1,300 sqft rental home that I'm rehabbing in GA.  Do i need to upgrade the breaker box from 100 to 200 amps?  How much is the average cost for the upgrade?  The stove & hot water heater are currently electric.  I am adding a new HVAC system the house did not previously have central air.  Thanks for your help!!!!!
