"If you are shopping around for an electrician stop right here. I was so nervous because the work I needed was substantial. We needed a new central air hookup,an upgraded and moved electrical panel and the outside meter and lines moved! I was nervous. Tommy was so sincere so reassuring, he made me feel completely at ease. And I was right. Right from the start Theresa kept me informed every minute. Tommy showed up with his crew,actually before 8 am and worked straight through until after 6pm. The work he did is impeccable. He is a type AAA and it shows in his work. I can't say enough about his professionalism and ability. He should be Long Island's Electrician! Thank you Tommy,credit and Theresa."

"Amazing. He was here several times, always arrived on time with all materials. Before every job the pricing was discussed and I paid exactly what was agreed upon with no surprises. The electrician was kind, considerate and caring and explained everything to me. He made suggestions and took the time to help me understand everything. I learnt this is a family business and being a small business owner myself It was such a pleasure to have him here. So many companies today you get no personalized attention. He was always reachable by email or phone. I would highly recommend him and will continue to use him."

"John was amazing. He explained everything well, and kept great lines of communication open throughout the job. This was especially true in dealing with the electric company. He went above and beyond to make sure everything with our new panel was set up the way we wanted and provided advice on other things we needed (like a basic ceiling fan install). I would definitely call John Julius Electric next time I need electrical work done."

FAQs for electrical wiring or panel upgrade projects in Riverhead, 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.
