A 2024 Reddit commenter said Brennan Electric replaced a number of outlets and switches, ran network wiring throughout the home and added several new outlets. A 2021 Reddit commenter said they were pleased with the company, which added outlets and ran wiring for about 8 network drops. A 2022 Google customer said electrical problems left their office with no heat in the middle of the winter, and the company evaluated the problem, expedited parts and had them running again the next day. Connecticut's state registry shows an active electrician licence, ELC.0202872-E1, with Brennan Electric as the holder of record. The Better Business Bureau gives the company an A+ grade, and on Google it has 5 stars from 5 ratings.

We had problems with our electrical service at my office no heat in the middle of the winter. They came out evaluated and expedited parts and had us up and running the next day! This company went above and beyond for us! I would give them 10 stars if I could!
