100A, 200A & 400A Upgrades in Haverhill, MA

Many older homes in Haverhill and the Merrimack Valley were built with 60A or 100A electrical service — not nearly enough for today's modern appliances, EV chargers, heat pumps, and smart home devices. A service upgrade brings your home up to current capacity and code.

  • 100A to 200A upgrades — the most common upgrade for older MA homes
  • 200A to 400A upgrades for large homes, EV fleets, or solar + battery storage
  • New meter socket and service entrance cable installation
  • Overhead to underground service conversion
  • Full permit application with the City of Haverhill
  • Eversource power shutoff and reconnection coordination
  • Load calculation to right-size your new service

FAQs

Service Upgrade Questions

How long does a service upgrade take? ▾
Most service upgrades are completed in a single day. The power will be off for several hours while we install the new meter socket and service entrance. Eversource reconnects power the same day in most cases.
Do I need Eversource involved for a service upgrade? ▾
Yes. Any service upgrade that changes the meter socket or service entrance requires Eversource to disconnect and reconnect the utility feed. Giardi Electric handles all coordination with Eversource so you don't have to.
Will a 200A service handle an EV charger? ▾
In most cases, yes. A 200A service provides plenty of capacity for a Level 2 EV charger alongside normal household loads. If you're adding multiple EVs or solar + battery storage, we may recommend 400A.
Does a service upgrade require a permit in Massachusetts? ▾
Yes — electrical service upgrades require both an electrical permit from the city and an application to Eversource. Giardi Electric handles both and ensures your project passes final inspection.
