Our Services
What Our Generator Installation Service Includes
Every home is different, which is why we start with a conversation about your power needs before recommending equipment. A growing family with a sump pump and medical devices needs a different setup than a homeowner who just wants the lights and refrigerator running during a short outage.
Our generator installation work covers:
- Standby generator installation with automatic transfer switches for whole-home backup power
- Portable generator installation, including manual transfer switches and properly wired inlet boxes
- Load calculations to size the generator correctly for your panel and household demand
- Permitting and inspection coordination with local building departments
- Generator repair for units that stall, fail to start, or trip breakers during an outage
- Generator maintenance plans to keep your system ready before storm season arrives
Signs Your Home Needs Generator Installation
Winter storms and summer outages do not care about your schedule, and a dark house with a full freezer is a stressful way to spend a night. If you have lost power more than once this year, or your household depends on medical equipment, a sump pump, or a home office, home generator installation turns a stressful outage into a minor inconvenience.
For homeowners who want backup power without the cost of a full standby system, portable generator installation offers a flexible, lower cost option that still keeps essential circuits running until the lights come back on.
Our Process
How Generator Installation Works From Call To Completion
Getting backup power installed does not have to be complicated. We walk every homeowner through the same clear process, from the first phone call to final testing.
-
Step 1: Home Power Assessment
A licensed electrician visits your property to review your electrical panel, discuss your backup power goals, and measure the space available for a standby or portable unit.
-
Step 2: Generator Sizing and Proposal
We calculate the wattage your home actually needs, recommend the right generator size, and provide straightforward pricing before any work begins.
-
Step 3: Installation and Transfer Switch Wiring
Our residential electrician team installs the generator pad or mounting, runs the electrical connections, and wires the transfer switch so power shifts automatically or manually without backfeeding the grid.
-
Step 4: Testing and Walkthrough
Once everything is connected, we test the system under load, confirm it meets local code, and walk you through startup, shutdown, and basic maintenance before we leave.

Home Generator Installation Across the Merrimack Valley
Amaury Castillo Electric Corp installs and services generators for homeowners throughout Lawrence and the surrounding Merrimack Valley, including Andover, North Andover, Methuen, Haverhill, Lowell, Dracut, Tyngsborough, Tewksbury, Reading, and Wilmington. Wherever you call home in the region, our residential electrician team can design a generator installation that fits your property and your budget.
Generator Maintenance and Repair For Merrimack Valley Homes
A generator that sits untouched between storms can fail exactly when you need it most. Routine generator maintenance catches worn parts, battery issues, and fuel problems before an outage puts them to the test.
We also handle generator repair for existing units, whether a standby system is throwing error codes or a portable generator will not hold a steady load. Common service needs include:
- Annual generator maintenance visits before storm season
- Battery testing and replacement for standby units
- Transfer switch troubleshooting and repair
- Fuel line and carburetor service on portable generators
- Generator repair for units that run rough, surge, or fail to start
- Post-storm inspections after heavy use
If your generator has not been serviced in over a year, it is worth a checkup before the next outage rather than after one.
Permits and Code Compliance for Generator Installation
Massachusetts requires permits and inspections for most standby generator installations, along with proper clearances from windows, doors, and property lines. As a licensed residential electrician, we handle the paperwork and inspection scheduling so your home generator installation passes code the first time, without you having to track down permits yourself.

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.
