"We previously used TFC Electric to install an upgraded electric panel with a hookup to our generator. From connection on the pole to the generator outside the garage, the work was above professional! So we called them for some interior and exterior lighting. Wow -- they suggested that for a similar price, the exterior floods could also be security cameras and connect into our Ring doorbell system. (They also knew Google, Lutron, etc.) The installation of two (one high on a garage) was amazing -- and they connected the light/cameras (through wifi extender they suggested) into our cloud-based system, tuned perfectly! Then the front door grotty lights were replaced with superb fixtures -- with Hue lights to match our interior system -- at Christmas our front door glows green! And they fixed my botched job of a new fixture at the side door and a broken exterior ground fault outlet box. The interior chandelier was initially hung too high for our tastes, but professionally. They insisted on coming back and putting it where we wanted. Innovation -- while hooking up the garage floodlight, they noted no lights in the garage "attic", but for a small bit more they would install fixtures and a switch -- what a difference! What are you doing still reading this review -- call them! Angie's List sometimes yields treasures -- this discovery is one!"

"Mike Connelly of Shamrock Electric Co. Coordinated the installation of my whole house Generac generator with PSEG long island and my plumber. He connected the automatic transfer switch and fully tested the system upon completion of the install. He has it set to run a test for 10 minutes once a week. My wife and I are extremely happy with the unit and the professional set-up by Shamrock Electric Company ."

"As a Building & General Contractor myself Newgrange electric is one of my best electrical sub contractors. Eddie the owner is very hard working. Always reliable, extremely professional and maintains an office manager Nicole who knows what's going on, on all their projects so you always have someone to contact during business hours. Eddies crew is based of long time employees that are very knowledgeable in there work. Eddie will always get back to you even after business hours, which is not the norm for many vendors. We need more contractors like this. Joe Algeri, Orchard Builders & Construction & Skyline Plumbing & Heating."

Customers say: Quality work

"I hired CPT Electric after another Home Advisor electrician was unresponsive after our initial contact. Cole Thomas responded quickly, gave good advice, and installed three GFCI outlets in different locations in my house. The work was done quickly and efficiently with a neat clean up. It did not look like anyone had been working after the job was complete. Cole is a real professional and charges a reasonable rate. I will be using Cole in the future for any electrical work that needs to be done in my home. Thanks, Cole."

FAQs for electrical for home addition or remodel installation projects in Holtsville, NY

Because installing coax outlets involves working around existing electrical wiring and confirming proper grounding, many homeowners prefer to hire a licensed electrician. A professional completes the work safely, secures the line behind the wall, and ensures the installation meets local code, which reduces the risk of damage or future repairs.

You still need a coaxial outlet for most cable-based internet services. The modem draws its signal from a cable line that terminates at a dedicated wall jack. Once the modem is online, your Wi-Fi router can broadcast the signal throughout the home, so the outlet’s location doesn’t affect wireless performance. If an existing jack is damaged or in an inconvenient spot, an electrician can move it or install a new one to maintain a strong, reliable connection.

Coaxial cable loses signal strength the farther it runs. A 50-foot length introduces noticeable loss, and a 100-foot stretch can drop the signal by roughly 30%. A weaker signal can result in a fuzzy picture or slower internet speeds. To maintain high performance, limit cable length whenever possible, select the correct cable grade, and route it efficiently. If your layout demands an exceptionally long run, an electrician can install an inline amplifier to boost the signal and maintain picture or data quality.
