Trinity Electrical Systems Inc.

Trinity Electrical Systems is a Medford, Massachusetts electrician built on the day-to-day calls — outlet swaps, panel upgrades, a fixture that needs rewiring — and the record keeps returning to one word: fast. On Google, 22 ratings run a clean five stars, and reviewers describe getting a same-day fix for a burnt outlet or an outage rather than a days-long wait. The company is run by Caio Pereira, whose Massachusetts electrician license is active with the state registry, and by his wife Emily — HomeAdvisor lists it as family-owned. Trinity says it covers Medford, Boston, Woburn, Somerville, Cambridge and a dozen surrounding towns, doing residential, commercial and industrial work. The written record goes back to 2020 and holds together across platforms rather than clustering on one site: Google, HomeAdvisor, Thumbtack and BBB all show the same pattern. Homeowners describe full rewiring jobs — a kitchen converted from gas to induction with new wiring and a breaker upgrade in a 2025 review, a bathroom rewired with new fixtures in a 2024 review, recessed lighting installed in a living room the same year. A BBB profile carries an A+ rating, and a 2023 review mentions a building inspector complimenting the neatness of the work. Worth knowing before calling: HomeAdvisor's own FAQ states Trinity does not offer emergency services, so a true after-hours emergency isn't what to expect, even though reviewers describe quick same-day scheduling for non-emergency issues. Sources also disagree on how long the company has been around — BBB records it as three years old, founded in August 2023, while HomeAdvisor and Thumbtack both list six years in business — worth asking directly if longevity matters to the decision. Trinity is a solid call for the residential work that fills its review history — rewiring, panel and lighting jobs, general troubleshooting — around Medford and the towns nearby, and the consistency of praise across four separate platforms is the strongest thing going for it. Confirm current pricing for the specific job, and don't plan on same-day service for a genuine after-hours emergency.
