"Ross was great as were the rest of his crew. I think I met almost all of them. The project included two new Leviton smart load panels and a new meter box as well as new underground service line which required working with PSEG. It was all taken care of professionally and efficiently on time and at a reasonable cost. The work was done in two stages as per my preference and budget over about 5 months. I had them come back for additional work unrelated to load panels installing outlets by 8 skylights and a new fan box. All done professionally. Will definitely use again. Low friction, cost effective, timely and high quality."

"Mike from No shorts electric was very prompt. He carefully inspected the entire electric panel and said that the source of the odor was something other than electrical. He was very methodical and courteous. He did not charge anything, even for a service call or for his time/travel. That was so pleasantly surprising. WIll gladly use him again and highly recommend him to others."

"I recently hired Sal at Hilite to ground a large number of the outlets in my home, add new outlets and new light fixtures, and I am thoroughly impressed with the outstanding service provided and overall expertise of Sal and his team. The team completed the work on schedule and demonstrated exceptional problem-solving skills, efficiently addressing unexpected issues as they arose throughout the process. Sal got the job done for a very reasonable price. Throughout the process, the Hilite team maintained clear communication, exhibited professionalism, and kept on track to get the job done within the agreed upon timeline. I highly recommend Sal and his team for any electrical work. I would certainly look forward to hiring them again for future projects."

FAQs for electrical wiring or panel upgrade projects in Rockville Centre, NY

While homeowners with substantial electrical knowledge might technically attempt a subpanel installation, most local building departments require permits and inspections for this type of work. Professional electricians understand local code requirements, can obtain necessary permits, and ensure the installation meets safety standards. Given the significant safety risks associated with incorrect electrical work, most homeowners benefit from hiring a licensed professional.

A standard subpanel installation takes an average of four to eight hours. This timeframe may extend if you're installing multiple subpanels or adding specialized circuits like those for spa equipment. Factors such as difficult access points, complex wiring paths, or permit processing times can also affect the overall project duration.

Adding a subpanel doesn't directly reduce electricity consumption or lower your utility bills. A subpanel simply redistributes power from your main panel to additional circuits. However, organizing your electrical system more efficiently may help prevent overloaded circuits and the associated problems. For actual cost savings, consider energy-efficient appliances and lighting instead.

The appropriate subpanel size depends on your specific electrical requirements. Consider the number and type of devices you'll be powering, potential future needs, and the capacity of your main electrical panel. An electrician can perform a load calculation to determine the most suitable amperage rating for your situation, ensuring you have adequate power without overpaying for unnecessary capacity.

A main electrical panel connects directly to your utility's power supply and contains your home's primary service disconnect. It distributes electricity throughout your entire house. A subpanel, by contrast, receives power from the main panel and redistributes it to a specific area of your home. Think of the main panel as the primary distribution point and the subpanel as a secondary branch that extends your electrical system's reach.

While electrical upgrades aren't as immediately visible as kitchen or bathroom renovations, they can contribute to your home's functionality and safety. Prospective buyers often appreciate updated electrical systems that can accommodate modern power demands. A properly installed subpanel that provides additional capacity for workshops, home offices, or future expansions could be an attractive feature for certain buyers, though the direct impact on home value varies by market.
