Expert Service Upgrades in Hartford County, CT

Many homes across Hartford County were built when 60-amp or 100-amp electrical service was standard. Today, those panels struggle to keep up with EV chargers, central air, home offices, and modern appliances. A service upgrade replaces your outdated panel and meter base with a higher-capacity system that meets current Connecticut electrical code. O'Connell's Electrical Contractors serves residential and commercial properties throughout Hartford County, including Hartford, West Hartford, Bloomfield, East Hartford, Wethersfield, Manchester, Newington, and Windsor. We assess your current service, walk you through your options before any work begins, and handle all labor, materials, and cleanup. Hartford County's mix of older Colonials, Cape Cods, and multi-family properties means service entrance conditions vary widely from property to property. We account for that on every job. When the work is done, we review everything with you and confirm it meets code. Call O'Connell's Electrical Contractors to schedule your service upgrade assessment in Hartford County.

I recently hired O’connell’s electric for a complete service upgrade from 100-amp to 200-amp, along with some additional wiring. From start to finish, the work was executed to the highest professional standard—clean, precise, and fully code-compliant. What truly stood out was Michael’s exceptional approach to the job. He was incredibly polite and courteous, took the time to thoroughly explain every step of the process, and answered all of our questions in clear, easy-to-understand terms. The upgrade was completed efficiently and with minimal disruption to our home, and the final result is outstanding. Beyond the technical expertise, he is simply an excellent human being—patient, respectful, and genuinely caring about doing the job right. I felt completely confident and well-informed throughout the entire project. I highly recommend Michael from O’Connell Electric to anyone needing electrical work. Professional, trustworthy, and truly top-tier. We will definitely use their services again and will be referring them to family and friends. Thank you for the outstanding work!

Mike is thorough and competent. He solved electrical issues that I could not. He’s prompt and tidy. His rates are reasonable. He doesn’t try to upsell you.

I requested the job get done on a Thursday Between 9 AM and 5 PM and Mike made it happen. Mike showed Up on time and the new 200 amp service was finished by 3 PM. Mike did a professional job, cleaned up and was very polite. I plan on hiring him again and will refer my friends who need electrical work done to Mike without any hesitation.
