Question: how much does it cost to upgrade electrical service in a house?
Answer: The standard for household power used to be 60 amps. But modern homes may need as many as 200 amps to run air conditioners, computer equipment, high-definition televisions, and high-tech home automation devices. The cost of upgrading your existing electrical service panel to a 100- or 200-amp panel is $800 to $3,000.
