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.

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.

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!

It was our first encounter with Haines Electric and I couldn’t be happier. Rich Haines is a true professional. It is still family owned and they take pride in having their name attached to the business. I’m always one to judge a contractor by his truck The Haines Electric truck was immaculate and he showed up promptly on time. Communication prior to the appointment was superb, as I received a number of text messages to confirm and was able to speak to Rich directly by phone to reschedule. They are by no means the cheapest electrician out there, but their professionalism and attention to detail makes it all worthwhile.
Response from the owner:Hi Douglas , we appreciate you taking the time to give us a review and so happy to hear your feedback of the service visit from start to finish.Thank you !

I called with an electrical issue Saturday night and the electrician showed up as promised Sunday morning. He opened the panel, tested the breakers and determined that there was a break in the wiring. He patiently opened light switches, outlets and ceiling lights until he found the break. He made the repair, tested and then retested after everything was put back in place. They now have a loyal customer in me I would happily recommend them to everyone

Electrical Panel Services

Your Electrical Panel Is the Heart of Your Home’s Power

Your electrical panel controls how power moves through your home. Every light, outlet, appliance, HVAC system, EV charger, generator transfer switch, and dedicated circuit depends on a safe, properly sized panel.

When a panel is outdated, overloaded, damaged, or no longer keeping up with modern electrical demand, it can create frustrating issues throughout the home, from tripping breakers and flickering lights to warm panels, buzzing sounds, and limited room for future upgrades.

Haines Electric provides complete electrical panel services throughout Nassau County, including panel repair, panel upgrades, panel installation, breaker replacement, service upgrades, and troubleshooting.

Panel Services We Provide

Electrical Panel Upgrades Increase capacity for EV chargers, HVAC, appliances, and modern power needs. Electrical Panel Repair Fix buzzing panels, tripping breakers, damaged breakers, and unsafe components.

Warning Signs

Signs Your Electrical Panel Needs Attention

Electrical panel problems often start small. If you notice these issues in your Nassau County home, it may be time for panel repair, breaker replacement, or a full electrical panel upgrade.

⚠️

Breakers Trip Often

Frequent breaker trips can point to overloaded circuits, failing breakers, or not enough panel capacity.

💡

Lights Flicker or Dim

If lights dim when appliances start, your panel may be struggling to distribute power properly.

🔊

Buzzing or Crackling

Unusual panel sounds can indicate loose connections, damaged breakers, or unsafe electrical arcing.

🔥

Burning Smells

A burning smell near the panel should be treated as urgent and inspected by a licensed electrician.

🔌

No Room for Circuits

If your panel has no space left, adding EV chargers, appliances, or dedicated circuits may require an upgrade.

🏠

Older 100 Amp Service

Many older homes need more capacity to safely support modern electrical demands and future upgrades.

Repair or Upgrade?

Does Your Panel Need a Repair, Replacement, or Full Upgrade?

Not every panel issue means you need a full upgrade. Haines Electric helps Nassau County homeowners understand whether the safest solution is a targeted repair, a breaker replacement, or a larger electrical panel upgrade.

Repair

Panel Repair May Be Enough If...

  • One breaker is failing or will not reset
  • A specific circuit is overloaded
  • The panel has a loose connection
  • There is a localized wiring issue

⚡

Professional diagnosis helps avoid guessing.

Upgrade

A Panel Upgrade May Be Better If...

Panel Size & Capacity

100 Amp vs 200 Amp Electrical Panels

One of the most common questions Nassau County homeowners ask is whether their current panel is large enough. The right answer depends on your home size, appliances, HVAC equipment, EV charging plans, renovations, and future electrical needs.

Panel Size Best For Common Limitations
100 Amp Smaller homes with basic electrical needs and fewer high-demand appliances. May struggle with EV chargers, central air, additions, electric ranges, or modern appliance loads.
150 Amp Some mid-size homes that need more capacity but may not require a full 200 amp upgrade. Still may be limited for larger renovations, EV charging, or multiple major electrical upgrades.
200 Amp Many modern homes with HVAC, EV chargers, generators, home offices, and larger appliance demands. Usually a strong fit for most residential upgrades, but a load calculation is still recommended.
400 Amp Larger homes, luxury properties, major additions, pools, large HVAC systems, or extensive electric equipment. More involved installation, utility coordination, and project planning may be required.

Not sure what size panel your home needs?

Haines Electric can evaluate your current panel, review your electrical demand, and recommend the safest option for your home.

Electrical Panel FAQ

Frequently Asked Questions About Electrical Panels

Get answers to common questions about electrical panel repairs, upgrades, breaker boxes, 200 amp service, and when to call a Nassau County electrician.

How do I know if my electrical panel needs to be upgraded?

Common signs include frequent breaker trips, flickering lights, buzzing sounds, burning smells, no room for new circuits, outdated 100 amp service, or plans to add EV chargers, HVAC equipment, generators, or major appliances.

Can an electrical panel be repaired instead of replaced?

Yes, some panel issues can be repaired, such as a failing breaker, loose connection, or localized circuit problem. If the panel is outdated, overloaded, damaged, or undersized, a full upgrade may be the safer long-term solution.

Is 200 amp service enough for most homes?

For many modern homes, 200 amp service is a strong fit, especially if the home has central air, EV charging, electric appliances, home offices, or future renovation plans. Larger homes or heavy electrical loads may require additional capacity.

Why is my electrical panel buzzing?

A buzzing panel may be caused by loose wiring, overloaded circuits, failing breakers, or electrical arcing. Loud or persistent buzzing should be inspected by a licensed electrician right away.

Do I need a panel upgrade for an EV charger?

Not always, but many Level 2 EV chargers require enough available panel capacity and a dedicated circuit. A licensed electrician can review your existing panel and determine whether an upgrade is needed.

How long does an electrical panel upgrade take?

Many residential panel upgrades can be completed in one day, but timing depends on the scope of work, permit requirements, utility coordination, inspection scheduling, and whether additional electrical work is needed.

Should I replace an old fuse box?

In many cases, yes. Fuse boxes are outdated and may not provide the capacity or convenience needed for modern electrical use. A licensed electrician can evaluate your system and recommend the safest option.
