Why Upgrading from 100-Amp to 200-Amp Service Matters in Today’s Homes

Not long ago, most homes in America could get by just fine with a 100-amp electrical service. Lights, a refrigerator, a TV, and maybe a clothes dryer were the big draws on the panel. But times have changed, and so have our electrical needs.
Today’s households are equipped with high-demand appliances, including electric car chargers, heat pumps, backup electric heat strips, hot tubs, and high-efficiency ovens. These devices aren’t “extras” anymore—they’re becoming standard in modern homes. The result? A 100-amp service simply can’t keep up with the demand without becoming overloaded.
The Modern Energy Landscape
Electric Vehicle Chargers (EVs): A Level 2 EV charger alone can draw 40 to 50 amps—half the capacity of an older 100-amp panel.
Heat Pumps with Backup Heat Strips: These strips can require 10 to 20 kW of power, which translates to 40 to 80 amps of draw.
Everyday Appliances: Ovens, dryers, microwaves, and even hot tubs are larger draws than in decades past.
Why 200 Amps is the New Standard
Upgrading to 200 amps isn’t about luxury—it’s about safety, convenience, and preparing for the future.
Safety: Overloaded panels can overheat, trip breakers, or even become a fire hazard.
Future-Proofing: A 200-amp service is quickly becoming a selling point in the housing market.
Comfort and Reliability: With more capacity, you can run your heat pump, cook dinner, charge the car, and do laundry—all at once—without worrying about overloads.

Upgrading to 200 amps is no longer just for large homes or high-end builds. It’s becoming the new baseline for the average family who wants to live comfortably and safely in a world where electric vehicles, efficient heating, and modern appliances are the norm.
If your home still has a 100-amp service, now is the time to consider upgrading. Think of it as preparing your house not just for today’s needs, but for the technology you’ll inevitably adopt tomorrow.
