Iannazzi Electrical Services is a third-generation Andover shop that traces itself back to 1945, when Michael J. Iannazzi built the company's original reputation; today the family's master electrician, Jacob William Iannazzi, holds the active Massachusetts electrician license behind the business, which does residential and commercial electrical work plus low-voltage systems like fire alarm, security, and data wiring across Massachusetts, New Hampshire, and Maine. BuildZoom's permit-based tally puts the company at 99 completed electrical permits, mostly commercial, with a score in the top 12% of the state's licensed contractors — a scale that lines up with the company's own description of medical, restaurant, retail, and brewery clients. In a 2020 review, a longtime commercial client called the company "top notch" across those same industries, and another 2020 review described a same-day emergency callout and light-fixture install at a shop. A 2014 review described a technician, Nolan, walking a customer through a repair that turned out tougher than expected. Its Better Business Bureau profile carries an A+ grade with no complaints on file. One thing worth flagging: there's little written feedback online for a company this established — the reviews on file run from 2014 to 2020, so there isn't a recent, first-hand account to point to. The company also describes an 81-year history dating to 1945, while the Better Business Bureau lists the current corporate entity as incorporated in 1989 with 37 years in business; that's consistent with a business that operated informally, or under a different name, before incorporating, but it's worth asking about directly if the exact history matters to you. Iannazzi Electrical Services looks best suited to commercial and larger residential electrical work — the permit record and reviews both point that way — backed by a licensed master electrician and a clean regulatory record. Confirm current turnaround times directly, since the online track record doesn't reach into the last several years.
Iannazzi Electrical Contractors is a top notch electrical firm. I have used their experienced team on many projects delivering medical, restaurant, retail, and brewery. I would highly recommend William J. Iannazzi for all electrical and consulting needs.
Called Joe first thing in the morning with a problem at our shop and he sent two techs right out. Also had them install new lights. They were quick, and their price was reasonable. Very pleased with the whole experience.
Very professional and the guys are so nice! Nolan is such a great service guy always explains whats going on and leaves you feeling that there is a resolution even though the job was much more difficult than normal...I always call these guys no matter what best in the area for sure!
