H&A Long Island Electrician

H&A Long Island Electrician operates from Mineola and maintains a perfect 5.0-star rating across 107 verified reviews, offering 24-hour availability every day of the week. The company handles both residential and commercial electrical projects across Nassau and Suffolk Counties, serving communities from Hempstead and Freeport on the south shore to Great Neck and Port Washington on the north shore, extending east through Babylon and Huntington.

What distinguishes this contractor is their specialization in modern electrical infrastructure upgrades. They install Tesla EV chargers, perform 200-amp panel upgrades, and replace outdated aluminum and knob-and-tube wiring , services increasingly in demand as Long Island homeowners prepare older properties for electric vehicle charging and increased power demands. The company also offers generator installation and provides free over-the-phone troubleshooting guidance.

Reviewers consistently highlight specific technicians who resolved urgent problems. Christopher repaired a short circuit that disabled a customer's heating system, completing the work in four hours. During a midnight power outage, Varun answered at 12:00am and arranged for technician Hans to arrive by 8:30am the same morning. For another customer, JT and Ramesh managed a complete house rewiring and Tesla Charger installation, coordinating the inspection process from start to finish.
