A previous vendor walked away from wiring a Generac standby generator into a home's solar and battery system. In a March 2026 review, the customer said David Ferreira of The Power Pro Electrical Services took it on along with a full smart-panel upgrade, diagnosed everything, and got the generator wired, configured and commissioned, after an earlier ESS install where the crew handled the permitting. The company, with a Lowell address, holds 5 stars from 55 Google ratings and an A+ from the BBB, where it is accredited; its own site says it has been in business 10 years, serves Chelmsford and towns from Westford and Billerica to Concord and Acton, and offers free estimates. DAVID FERREIRA holds Massachusetts electrician licence #23573-EL-A, which is active. Mini-split work is the other job that keeps showing up: four reviews from November 2024 to May 2025 describe mini-split installs. In the November 2024 one, the customer had ceiling cartridges installed, which meant David working in the crawlspace of an 1890s farmhouse. A May 2025 customer had mini splits and a heat pump installed in a split-level house in about three days. An August 2026 customer had the electrical panel in an older house upgraded before a mini split went in. The smaller jobs read the same way. A July 2026 customer had recessed and pendant lighting, bathroom heated floors, new outlets and three outdoor cameras done, with the extra work finished in one afternoon. A May 2026 customer, newly moved in with a list from a home inspection, said three days of work came in at the originally estimated price. In February 2025, the crew reattached service wires a storm had ripped off the side of a house. A July 2025 customer said David came the same day they called and sent his crew back to fix the problem later that day.
David upgraded our electrical panel before installing a mini split. He was professional and provided guidance surrounding our questions and was clear and responsive even when we added changes at the last minute. His entire team were excellent, worked hard ~with clean and impressive results. We have an older house and the electrical panel was in dire need of an upgrade. David kept in touch throughout, made useful suggestions all which ended with a job going above and beyond. Very much highly recommend !!
We had a lot of electrical upgrades to make to our new home, including moving junction boxes for light fixtures, installing recessed lighting, pendant lights, and heated floors in the bathroom, and switching out old outlets, light switches, and light fixtures. The team also installed three outdoor Google cameras for us, including new outlets in the garage and attic to accommodate them, and completed all that additional work in just one afternoon. David and his team were very responsive. They do great electrical work. Any aesthetic changes that we requested were quickly addressed by David and the team. Everyone was very friendly and pleasant to work with.
My wife and I just moved into our new home, and received a lot of electrical issues that we needed to address in our home inspection. We were referred to David and his team by our realtor, and they did a fantastic job. There were 3 full days of electrical work that needed to get done, but they were always on time, worked late if needed, and did high quality work. Their estimates were fair and their final invoices were always the same price as originally estimated. I could reach them by text any time, add new items for them to take care of, and they were always amenable. We will be using them in the future if ever needed, and I would recommend them to anyone.
David and his team were all the things you want when you call an electrician: timely, neat, clear communication and reasonably priced. I highly recommend.
Huge shoutout to David and his crew! They just finished a complicated ESS install for me and did a phenomenal job. Their work quality is top-notch and their attention to detail is rare to find these days. They were incredibly reliable throughout the entire process—handling all the permitting and following through on every single promise. Five stars! Update, hired David again for another project: **Can't recommend David and The Power Pro highly enough.** David took on a big, complicated electrical project at our home — a full smart-panel upgrade plus integrating our Generac standby generator with our solar and battery system — and knocked it out of the park. From start to finish he was professional, communicative, and clearly takes real pride in his work. When our power was down, David worked tirelessly to get us back up and running, and did it with minimal disruption to our household — no small feat given how involved the job was. He's the rare tradesperson who's both highly skilled and genuinely conscientious. Also, the generator work truly stood out. Our previous vendor wouldn't even touch the generator integration — it was too complex and they walked away from it. David stepped right in, diagnosed everything, and got our Generac wired, configured, and commissioned properly. He was timely, transparent, and stuck with it until every last detail was working perfectly. If you're looking for a master electrician who's knowledgeable, reliable, honest, and does exceptional work, David is your guy. Five stars, hands down — we'll be calling him for everything going forward.
