Upgrade your home's service capacity to safely handle EVs, HVAC systems, and everything a modern home actually runs.
Ready for More Power?
EV charger, heat pump, or future-proofing your home — a service upgrade is a one-time investment that pays off for decades.
MODERN HOMES NEED MODERN SERVICE — MORE POWER, SAFELY DELIVERED
If your home still has 60A or 100A electrical service, you’re running on an infrastructure budget designed for the era of window air conditioners and black-and-white television sets. Today’s homes run central AC, heat pumps, electric dryers, induction stoves, EV chargers, home offices, and smart home equipment simultaneously — and older service can’t keep up without tripping breakers, dimming lights, and stressing the wiring throughout the house.
High Power Inc. upgrades residential electrical service from 100A to 200A (the current standard) or higher, coordinating with ComEd and pulling all required permits.
- A 100A-to-200A upgrade is a one-day project that pays off for the entire remaining life of your home.
- We handle ComEd coordination, permit filing, and the city inspection — you make zero calls to the utility company.
- Bundle your service upgrade with an EV charger install and save on permit fees and service disconnect scheduling.
- Modern homes running EVs, heat pumps, and induction appliances can't operate safely on 100A service — don't wait for a failure to find out.

What a Service Upgrade Includes
