"Tom is excellent. I had him install three ceiling fans in my vacation home two years ago and the work was perfect. He pays attention to detail and the house is spotless when he leaves. This time I upgraded the electrical work in this home. Tom added outlets, repaired ballasts, replaced outdoor outlet covers and added GFI outlets as needed. I also requested outlets into the living room floor and this was done perfectly. Tom noted what electrical work was necessary and completed everything. As usual, the house was spotless."

"Mike and his team are awesome! They upgraded my electric service to 200 amps, installed a new light fixture in my dining room, installed high hats in my kitchen, and replaced a number of other fixtures and outlets around my home. The work was completed in a single day and everything looks great! I've recommended Shamrock to my parents, and will definitely use them for future electrical work."

"Replacing fan went very well. There were 2 workers and they had a very good portable light because it was dark at the time of the appt. I would definitely hire again. Highly recommend BQ Electric. Thank you!"

"Excellent Service & Professional Work I recently had Certified Electricians of Long Island upgrade my electrical service from 100 amps to 200 amps, including the installation of a new electrical panel and meter box. I couldn’t be happier with the job they did. From start to finish, the entire process was professional, efficient, and handled with great attention to detail. The work was done neatly, everything was explained clearly, and the job was completed exactly as promised. It’s clear that they take pride in their work and care about doing the job correctly, not just getting it done. I would highly recommend Certified Electricians of Long Island to anyone looking for a reliable, professional electrical contractor. Excellent work from start to finish. Five stars! ⭐⭐⭐⭐⭐"

"Came to my house the same day and completed the job. Mike the electrician was a nice guy and did a good job. $200 the first hour and $100 each additional hour. Changed existing ceiling fan, switches and outlets. I already had the parts, took 3+ hours, cost almost $500 with tax. Not sure if this is standard. I called them after another electrician who was supposed to come that day canceled."

Old house with outdated electrical system unfortunately, but I was left with everything working! Extremely satisfied, would use them again when I upgrade my electrical system."

FAQs for electrical wiring or panel upgrade projects in Commack, NY

Yes, a licensed electrician is essential for this project. Running an electrical service from the road to your house involves connecting to utility power lines, complying with national and local electrical codes, and safely handling high-voltage systems. 

Licensed professionals understand proper wire sizing, grounding requirements, and voltage drop calculations needed for safe installation. Most jurisdictions require permits and inspections that only certified professionals can obtain. The safety risks and potential for property damage make this project inappropriate for DIY attempts.

Overhead installations are less expensive than underground options. For a 1000-foot run, overhead service costs between $8,000 and $15,000, while underground service ranges from $10,000 to $25,000. 

Overhead lines require less labor and fewer materials since they don't need trenching or conduit. However, underground lines offer better protection from weather events and aesthetic benefits. Your decision should balance your budget constraints with long-term reliability and visual preferences.

You might need to upgrade your electrical panel depending on your power requirements. If your existing panel cannot handle the additional load from the extended service, upgrading to a 200-amp service (costing $750 to $2,000) may be necessary. 

A licensed electrician can evaluate your current system and determine if an upgrade is required. Factors include what you'll be powering at the end of the line, existing electrical demand, and whether voltage drop over the distance will affect performance.

Running electric service from the road to a house requires electrical permits from your local building department, costing between $500 and $2,000 depending on your location. You may also need excavation permits for trenching work if installing an underground service. Your utility company will have its own application process for connecting to its grid. A licensed electrical contractor can handle all the necessary permit applications as part of their service, ensuring your installation meets all local code requirements.
