A lot of times, when you read reviews, you wonder whether they're genuine. In this case, I can confidently say this one is. I met Rich and his team at E.H. Haines Electric when I called them for some work on my pool. From the start, they were friendly, professional, and knowledgeable. They arrived when they said they would, completed the job efficiently, and delivered exactly what they promised. I needed Rich to come back a few times for follow-up items, which he graciously did without hesitation. The best way to describe Rich and his company is that they do what they say they're going to do, when they say they're going to do it. I highly recommend Rich and his team at E.H. Haines Electric for any electrical needs. Their professionalism, reliability, and commitment to customer service are truly outstanding.

This is the second time Mike has serviced my house . In every way , his professionalism and his workmanship were of the highest quality. And it is always a pleasure to deal with a thoughtful and kind individual, and Mike is that type of person. He represents the quality of a Haines Electric Company’s experience.

Kelley Shields
I am thrilled with the service that Haines Electric provided. I recently purchased a new stove w/convection-electric oven that required a 220 line, which I did not realize when I purchased it. I learned that I needed a new line behind the stove when the plumber was there to install the appliance and hook up the gas. Suffice it to say I was aggravated with myself for not knowing more about what I was buying, but the responsiveness of Haines to get to us as soon as they did in that week, determine the scope of the work and return to complete it within a few days really turned things around for me and this new, significant investment. They are very courteous and highly skilled providers and I highly recommend them.

Rich and Mike from EH Haines Electric Corp did outstanding work for us in our garage and yard. They were punctual, professional, detail-oriented, and the quality of the work was excellent from start to finish. It’s refreshing to work with honest, friendly people who clearly take pride in what they do — highly recommend them.
Carol Schneck-Hamer
We’ve used Haines twice so far and will continue to use them for all of our electrical needs. They’re professional, knowledgeable and have very fair pricing. It’s a pleasure to do business with them and to recommend them.

A family owned business that you can trust. After my husband received a suspiciously high quote from another well known company I came across E.H. Haines. My husband contacted them and the owner of the company came to inspect and give a quote for the installation of an outlet to plug in an electric car charger. The quote was more than 50% less than what the other company quoted and he said they could do the job the next day. On the day of service, two workers arrived and the first thing they did was put booties on to protect the floors. They were so efficient, and explained everything they were doing in advance. In the process of preparing to install the new outlet they found an error the previous electricians did and fixed the problem at no extra cost. The job was completed quickly and they even cleaned up the work area before leaving. They were also kind enough to wait about 15 minutes for my husband to get home from work so he could test out the charger and make sure everything was working correctly. If you are in need of an electrician and want the job done right then do not hesitate to contact E.H. Haines for a professional and cost effective job. You will not be disappointed!

Common Electrical Problems

Electrical Issues Nassau County Homeowners Call Us For

Not every electrical problem starts with a total outage. Small warning signs like flickering lights, dead outlets, warm switches, or tripping breakers can point to wiring, circuit, panel, or safety issues that should be checked by a licensed electrician.

💡

Lights Flicker When Appliances Turn On

Dimming or flickering lights may point to overloaded circuits, appliance startup load, wiring issues, or an electrical panel that needs evaluation.

🔌

Some Outlets Stopped Working

Dead outlets can be caused by tripped GFCI protection, failed receptacles, loose wiring, or circuit problems inside the home.

⚡

Half the House Lost Power

Partial power loss may involve a utility issue, damaged connection, failing panel component, or deeper electrical distribution problem.

🧯

Breakers Keep Tripping

Frequent breaker trips are often caused by overloaded circuits, appliance issues, short circuits, ground faults, or an undersized electrical system.

🌡️

Outlets Feel Warm or Look Discolored

Warm outlets, scorch marks, or burning smells can signal loose wiring, damaged receptacles, or unsafe electrical connections.

🏠

Older Panel Can’t Keep Up

Older 100-amp panels and outdated breaker systems may struggle with EV chargers, central AC, renovations, and modern home electrical loads.

FAQ

Frequently Asked Questions From Nassau County Homeowners

Get answers to common electrical questions about flickering lights, tripping breakers, outdated panels, EV chargers, home electrical safety, and working with Haines Electric.

Why do my breakers keep tripping?

Breakers usually trip when a circuit is overloaded, a device is drawing too much power, or there is a wiring or panel issue. If breakers trip often, it is a sign your electrical system should be inspected by a licensed electrician.

Why do lights flicker when appliances turn on?

A brief flicker can happen when large appliances start up, but frequent flickering may point to overloaded circuits, loose wiring, or an outdated electrical panel. This is common in older Nassau County and Long Island homes.

What are signs of electrical problems in an older home?

Common warning signs include flickering lights, warm outlets, dead outlets, buzzing sounds, burning smells, frequent breaker trips, and outdated panels or fuse boxes. These issues should be checked before they become larger safety concerns.

Do I need a 200 amp electrical panel?

Many modern homes benefit from 200 amp service, especially if they have central air, electric appliances, EV chargers, additions, home offices, or outdoor equipment. A licensed electrician can perform a load evaluation to determine what your home needs.

Can my electrical panel handle an EV charger?

It depends on your panel size, current electrical load, available breaker space, and charger type. Many Level 2 EV chargers require dedicated wiring and enough panel capacity to operate safely.

Why did half my house lose power?

Partial power loss can be caused by a utility issue, a loose service connection, a failing panel component, or a circuit problem. If breakers are not tripped and only part of the home has power, the issue should be professionally diagnosed.

Why did some outlets stop working?

Dead outlets can be caused by a tripped GFCI outlet, a partially tripped breaker, a failed outlet, loose wiring, or a larger circuit issue. If resetting breakers and GFCI outlets does not restore power, an electrician should inspect the problem.

When should I call an electrician?

Call an electrician if you notice burning smells, buzzing, warm outlets, frequent breaker trips, flickering lights, partial power loss, or outlets that stop working. These can be signs of wiring, circuit, or panel issues that should not be ignored.
