Family Owned & Operated. Since 1967, A+ Rating With The BBB. No Subcontractors. Licensed Bonded and Insured. Emergency calls.

"I'm glad we hired A and Z. Barry Goldstein gave us a call and come to our residence to look at the work needed. Barry is a great and sincere person and we enjoy the small talk but got to business. We were in need of GFCI electric switches in the kitchen, bathroom, and other areas. Plus, we need new electrical outlets in our closets in both bedrooms and have the pulley taken out, and ad a fixture on the outside of the closet. We also had a hazard with the powerline where the clamps that are attached to the outside wall of the house were hanging out. Plus the kitchen exhaust fan and the ceiling fan needed to be installed and they did. The crew explained what is expected in the process and the price. They placed it back to her tight in order for us to get COMED to fix the wiring. They came and fixed the job and did it cleanly and professionally. The crew was great to talk to and we felt they value customer service no matter what the job. We like their overall work and are responsive. I recommend A to Z for anyone looking for small to big jobs. Great job they did."

Electrical for home addition or remodel installations FAQs

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.
