Stone Electric Corp. is owned and operated by Shaun M Stone. We are a family owned business focusing primarily on residential and commercial work. We believe making relationships and quality of work are the two most important factors when it comes to business. We come from a long family history of IBEW union trained electricians. My father has spent the last 40 years working in the industry. I myself plan to do the same. The customer always comes first. We work clean and always communicate the project to the best of our abilities to ensure our customer satisfaction! We are licensed and insured to complete your next home project!

"I had a disappointing experience with Stone Electric. They charged $2400 via Zelle for AC installation. When the electrician finally showed up, they could have been more professional and seemed to need more skills to handle the job efficiently. They installed a drain pipe higher than needed so drainage didn't occur; they left the freon gas pipe leaking. There was a six-month warranty, and when I called them to fix it the next day of installation, they kept blaming the head of the unit rather than the installation, which went wrong. Their unhelpful response and refusal to take responsibility were disappointing. I called Diakin company, and they discovered the real problem. I have to pay an additional $1100 to another company to refix the mistake they made. The unit was leaking water and frozen gas the day they installed it. On the phone, Mark, the head project guy, was rude and refused to take responsibility. Instead of a check, they took money via Zelle. Be cautious."

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