Do You Need an Electrical Panel Upgrade in Groton, MA?
If you are living in a colonial, cape, or mid-century home in Groton and your breakers trip regularly, your panel is the most likely cause. Homes built before the 1980s were typically wired for 100-amp service, which was adequate at the time but insufficient for today’s electrical loads. Signs you need an upgrade include breakers that trip when you run the AC and microwave at the same time, a home inspector flagging the panel during a sale, no room to add circuits for a new appliance or EV charger, or a panel that uses fuses rather than breakers. 128 Plumbing, Heating, Cooling & Electric assesses your existing panel and provides a clear, upfront price for the upgrade.

Frequently Asked Questions
How do I know if my Groton, MA home needs an electrical panel upgrade?
Clear signs that your Groton home needs a panel upgrade include circuit breakers that trip frequently under normal household loads, lights that dim when large appliances turn on, a panel that uses fuses instead of breakers, no room to add new circuits, a home inspector flagging the panel during a sale, or a panel that is 25 to 30 years old. Many colonial and mid-century homes in Groton were built with 100-amp service, which is no longer adequate for central AC, EV chargers, and modern appliances.
What does an electrical panel upgrade cost in Groton, MA?
The cost of a panel upgrade in Groton depends on your current panel size, the target amperage (most upgrades move from 100-amp to 200-amp service), whether the meter socket and service entrance need to be updated, and permit fees. 128 Plumbing, Heating, Cooling & Electric provides a detailed, itemized estimate before any work begins. Financing is available for qualifying homeowners.
How long does an electrical panel upgrade take in a Groton home?
A standard 100-amp to 200-amp panel upgrade is typically completed in one day. The process involves shutting off power to the home for several hours while the new panel is installed, circuits are transferred, and connections are made. We coordinate the utility disconnection in advance so there are no delays. Power is restored before we leave and the installation is inspected to code.
Will I need a permit for an electrical panel upgrade in Groton, MA?
Yes, electrical panel upgrades require a permit in Groton and throughout Massachusetts. 128 Plumbing, Heating, Cooling & Electric handles all permit applications on your behalf. The work is then inspected by the local electrical inspector before the permit is closed. This documentation is important: lenders, buyers, and insurance companies may request proof of permitted electrical work. Never hire a contractor who suggests skipping the permit for this type of work.
Can I add central AC or an EV charger to my Groton home without upgrading the panel first?
In most cases, no. Central AC typically requires a dedicated 240-volt, 30 to 60-amp circuit. A Level 2 EV charger requires a dedicated 240-volt, 30 to 50-amp circuit. If your existing panel is already at or near capacity, adding either of these without a panel upgrade creates a safety risk and will likely cause chronic breaker trips. Our technicians will assess your current panel load before recommending whether an upgrade is necessary.
