Heat pumps, EV chargers, induction ranges and home offices all add electrical load. Many older Ohio homes still run on 60 or 100-amp service, and some have panels that are no longer considered safe.
Signs your panel needs attention
- Breakers trip often, especially when two appliances run together
- Lights dim when the AC or microwave kicks on
- A fuse box, or a panel brand known for problems (ask an electrician to check)
- Warm, buzzing or scorched breakers, or a burning smell. Call an electrician right away.
- You’re adding an EV charger, heat pump, hot tub or addition
What it costs in Ohio
A 100 to 200-amp panel upgrade typically costs $1,800 to $4,500, including permit and inspection. If the utility needs to upgrade the service line or meter, add time and sometimes cost. See the full electrical cost guide.
Licensing and permits
Ohio licenses electrical contractors through the Ohio Construction Industry Licensing Board (OCILB), and most cities require a permit and inspection for panel work. Ask for the contractor’s license number and confirm the permit is pulled for your address before work starts.
Planning an EV charger?
A Level 2 charger typically costs $800 to $2,500 installed. Your electrician should do a load calculation first; sometimes a load-management device avoids a full panel upgrade. Compare EV charger installers.
