What Our Electrical Service Upgrades Include
A whole-house service upgrade replaces the equipment between the utility line and your home's main panel, including the meter base, service entrance cable, and sometimes the weatherhead or mast. This is different from a simple panel swap. It is the foundation that determines how much power your home can safely draw at once. Many older homes across the Merrimack Valley, from vintage triple-deckers in Lawrence to older capes in Andover, still run on service sizes that were never built for modern living.
Homeowners typically reach out for this service when they're:
- Adding central air conditioning, a hot tub, or other high-draw equipment
- Upgrading to a 200 amp service upgrade from an older 60 or 100 amp setup
- Installing a home EV charger installation or planning solar panels
- Dealing with a damaged, corroded, or flagged electric meter base
- Preparing for a home addition or major remodel
- Replacing an aging service that no longer meets current code
Our Process
How The Upgrade Process Works
Replacing your home's electrical service means coordinating with the utility company, pulling permits, and shutting off power for part of the day. We manage every step so you are never left guessing what comes next.
-
Step 1: Site Evaluation and Load Assessment
A licensed electrician visits your home to inspect the existing service, calculate your current and future power needs, and confirm whether a 200 amp service upgrade or different size fits your household.
-
Step 2: Permitting and Utility Coordination
We pull the required local permits and schedule the utility disconnect and reconnect, handling the paperwork that trips up most DIY attempts at electrical installation.
-
Step 3: Service and Meter Replacement
Our crew replaces the service entrance cable, meter base, and connection points, performing a full electric meter replacement where the existing equipment is outdated or damaged.
-
Step 4: Inspection and Power Restoration
Once the new service passes local inspection, the utility reconnects power and we test every circuit to confirm your home is running safely on its upgraded system.

Signs Your Home Needs a Service Upgrade
Most homeowners do not think about their electrical service until something forces the issue. A few warning signs are worth acting on before they turn into a bigger problem.
- Breakers trip regularly when running multiple appliances at once
- Your home still has a 60 or 100 amp service and you're adding major appliances
- The meter base shows rust, scorch marks, or visible damage
- Lights dim when the HVAC system or a large appliance kicks on
- You're planning an EV charger, solar panels, or a home addition
- Your insurance company or a home inspector flagged the current service
If any of these sound familiar, it's worth having a residential electrician evaluate your home's service size before you commit to new appliances or a renovation. An undersized service strains every circuit behind it, and waiting usually means a more expensive fix down the road.
Common Questions
Electrical Service Upgrade FAQs
A few questions we hear often from homeowners across the Merrimack Valley considering a service upgrade.
How do I know if I need a 200 amp service upgrade?
If your home currently runs on 60 or 100 amps and you're adding central air, an EV charger, a hot tub, or solar panels, a 200 amp service upgrade gives you the headroom to run everything without overloading the system. We assess your home's actual load before recommending a size.
Who handles the electric meter replacement, you or the utility company?
We handle the physical meter base replacement and service entrance work, then coordinate directly with the utility company for the disconnect, reconnect, and final meter installation. You do not need to call the utility yourself.
How long does a whole-house service upgrade take?
Most residential service upgrades take one full day, though the exact timeline depends on utility scheduling for the disconnect and reconnect. We confirm a realistic window with you before work begins so you can plan around the power outage.
Will I lose power during the upgrade?
Yes, power is off for part of the day while we replace the service equipment and the utility completes the reconnect. We let you know the expected outage window in advance so you can plan around it.

Mr. Castillo was prompt for the scheduled appointment, he came equipped with his tools/van/uniform. He went to work immediately, friendly, knew where to trouble shoot the electrical problem, corrected the problem within one hour of arrival while running down to the basement and up to the second floor bedroom several times where my daughters lights had gone out. I recommend this electrical expert to repair your electrical issues and he can also communicate in spanish , I give this company five stars *****!

I recently had several electrical issues at my home and was fortunate to find Amubury. He arrived promptly and was able to accurately diagnose the problems within minutes. I was incredibly impressed that he was able to fix everything in just a couple of hours. He even took the initiative to run out and purchase a necessary replacement part himself, which kept the process moving efficiently without any delays. Throughout the entire experience, Amubury was professional, courteous, and highly efficient. What stood out most was how thorough he was—he took the time to clearly explain the issues and walked me through the solutions, making sure all of my questions were answered. His pricing was very reasonable given the high quality and speed of his work. I was genuinely impressed and would highly recommend his services to anyone in the area. I will certainly be calling him again for any future electrical needs!

I was lucky enough to meet Amaury when I moved into my “new” home almost 10 years ago and he has been my go- to for everything electrical since! From installing a new fan on a cathedral ceiling to recessed and living room spotlights to changing out fan switches in bathrooms - he has done it all. Fast, responsive, fair and courteous- I really can’t say enough about Amaury, he truly is the BEST. Thanks Amaury!

We lucked out when I found Amaury on Angie's List years ago. Since then, he's fixed issues that have cropped up, installed a generator hook-up, and then replaced our entire (very old) electrical panel. He's responsive, thorough, knowledgable, insightful, voluntarily explains things and is fairly priced. Cannot recommend him enough!

Couldn’t be happier with our electric panel upgrade! From start to finish, the process was smooth and stress-free. Amaury was knowledgeable, respectful of our home, and did excellent work. Everything works perfectly and the upgrade gives us real peace of mind. I’d absolutely use them again.

Amaury quickly came over to check over the electrical wiring for our generator and electrical box, making a couple of thoughtful suggestions and quickly ensuring that we had heat in the event of a power outage in the Jan '26 snowstorm. Would recommend Amaury for any number of electrical work.

Amaury was super knowledgeable, efficient (he didn’t waste time), and I appreciate that he was conscious of the neat and clean look of the job putting in some complicated ceiling lighting. He asked me my opinion along the way so as to get just what I wanted while completing the job. And he left no mess behind. Thank you Amaury- first time using your service. Looking forward to having you as a reliable electrician for future jobs.
