"Great experience from start to finish. My wife and I needed to have 2 ceiling fans and light kits installed. The work was scheduled quickly and TFC Electrical Services was even able to do the job earlier than expected. Tom and Ralph arrived as scheduled, on time and we were given a fair price quote. They had to install electrical wiring and box in our bedroom ceiling prior to installing the fan and light. They took the time to protect our furniture and floors by covering everything with protective tarps. Additionally, the installed a fan and light kit in an adjacent staircase. The concern and respect that they showed for our home was admirable and appreciated. The installations were neat, clean and expertly completed. They completed all the work in about 3 hours. TFC Electrical Services should be a model for “ALL” other electrical contractors. Any future electrical work in my home will be offered to this company. Thank you Theresa, Tom and Ralph."

"From start to finish, Best Quality Electric delivered an exceptional, white-glove experience. The process began with a dedicated consultation that was educational, detailed, and thoughtfully planned—setting a clear vision before any work even began. The following day, the team arrived precisely on time and immediately demonstrated a level of professionalism that is rare to find. Shoe protection was used, and every floor and piece of furniture was carefully covered. Their respect for the home was as impressive as their craftsmanship. Watching the two electricians work was remarkable. They operated in perfect sequence, anticipating each other’s next step, covering every single detail with precision. Not one question went unanswered—each was met with patience, clarity, and deep expertise that inspired complete confidence. Best Quality Electric truly lives up to its name. This is not just electrical work—it’s a refined, high-standard service experience. Bold, meticulous Toptier work!"

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.
