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.

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.

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

Modern Power Demands

Why Nassau County Homes Need More Electrical Capacity

Many Long Island homes were built before today’s electrical demands existed. Older panels may have been fine for basic lighting, outlets, and appliances, but modern homes often need more capacity for larger equipment, dedicated circuits, and future upgrades.

If your electrical panel is full, outdated, or struggling to keep up, a panel upgrade can help improve safety, reliability, and available power throughout your home.

  • Level 2 EV charger installation
  • Central air, mini-splits, and heat pumps
  • Kitchen remodels and major appliances
  • Home offices and modern electronics
  • Generators, hot tubs, pools, and outdoor living spaces

Upgrade Goals

More Capacity Support new circuits, appliances, and electrical equipment.
Better Reliability Reduce nuisance trips, dimming lights, and overloaded circuits.
Future-Ready Power Prepare your home for EVs, renovations, and modern upgrades.
Upgrade Warning Signs

Signs Your Home May Need an Electrical Panel Upgrade

Panel upgrades are often recommended when your electrical system can no longer safely or reliably support your home’s power needs.

01

Your Home Has 100 Amp Service

Older 100 amp panels may not provide enough capacity for EV chargers, HVAC upgrades, and modern appliances.

02

No Room for New Breakers

If your panel is full, adding dedicated circuits for appliances, chargers, or renovations may require an upgrade.

03

Breakers Trip Frequently

Repeated trips can indicate overloaded circuits, aging equipment, or a panel that is no longer keeping up.

04

Lights Dim When Appliances Start

Dimming lights can be a sign that large appliances are pulling more power than your system can comfortably handle.

05

You Are Adding Major Equipment

EV chargers, central air, mini-splits, hot tubs, and generators often require additional electrical capacity.

06

Your Panel Is Buzzing or Warm

Buzzing, heat, or burning smells should be inspected immediately and may point to a repair or upgrade need.

100 Amp vs 200 Amp

What Size Electrical Panel Does Your Home Need?

Most Nassau County homeowners asking about panel upgrades are really asking one question: is my current panel large enough for the way my home uses power today?

100 Amp Older Service

A 100 amp panel may work for smaller homes with basic electrical needs, but it can become limiting when adding modern appliances, HVAC equipment, or EV charging.

  • Common in older homes
  • Limited room for new circuits
  • May struggle with modern loads
200 Amp Modern Standard

A 200 amp panel is often the right fit for modern homes that need safer capacity for EV chargers, central air, kitchen remodels, home offices, and future upgrades.

  • Better capacity for today’s homes
  • Supports more dedicated circuits
  • Often recommended for major upgrades
400 Amp Large Homes

Larger homes, major additions, pools, hot tubs, luxury kitchens, and heavy electrical loads may require more capacity than a standard 200 amp service.

  • Large or high-demand properties
  • Major renovations or additions
  • More involved planning required

Not sure if you need 200 amp service?

Haines Electric can review your current electrical panel, planned upgrades, and overall home power demand to recommend the safest option.

Read the 200 Amp Guide
Upgrade Process

What Happens During an Electrical Panel Upgrade?

Many homeowners are surprised to learn that most electrical panel upgrades can be completed in a single day. Our team handles the process from start to finish, including permits, inspections, and coordination when required.

1

Evaluate Your Existing Service

We inspect your current panel, available capacity, electrical loads, and future power needs.

2

Review Upgrade Options

We explain whether a repair, replacement, or service upgrade makes the most sense for your home.

3

Permits & Coordination

We handle permit requirements and coordinate the project as needed.

4

Panel Installation

The old panel is removed and replaced with a modern electrical panel designed for your home's needs.

5

Testing & Inspection

We verify proper operation, label circuits, and ensure everything is functioning safely.

Good to know: Most panel upgrades require only a temporary power shutdown during installation. We work efficiently to minimize disruption to your home.
Cost Factors

What Affects the Cost of an Electrical Panel Upgrade?

Every home is different. The cost of an electrical panel upgrade depends on your current service, the size of the new panel, utility requirements, permit needs, grounding, and any related electrical work.

01

Current Panel Condition

Older, damaged, overloaded, or unsafe panels may require additional work during replacement.

02

Service Size

Upgrading from 100 amp to 200 amp service is different from replacing a panel with the same capacity.

03

New Circuits

EV chargers, appliances, HVAC equipment, and remodels may require dedicated circuits or additional wiring.

04

Grounding & Code Updates

Grounding, bonding, surge protection, and code-related updates may be needed for a safe installation.

05

Permits & Inspections

Some panel upgrades require local permits, inspections, and coordination with utility requirements.

06

Home Layout

Panel location, accessibility, meter location, and existing wiring can all affect the scope of work.

Repair vs Upgrade

Should You Repair Your Panel or Upgrade It?

Some electrical panel problems can be repaired. Others are signs that the panel is outdated, overloaded, or no longer the safest option for your home.

Repair May Work

Panel Repair

A repair may be enough when the issue is isolated to one breaker, one circuit, or a specific connection.

  • One breaker is failing
  • A breaker will not reset
  • A specific circuit has an issue
  • The panel is still in good condition
Explore Panel Repair
Upgrade May Be Better

Panel Upgrade

An upgrade may be the safer long-term solution when your panel is old, full, overloaded, or not built for modern power demands.

  • Your home has 100 amp service
  • You are adding major equipment
  • The panel is full or outdated
  • Breakers trip in multiple areas

Panel Upgrade FAQ

Electrical Panel Upgrade Questions

Get answers to common questions about electrical panel upgrades, 200 amp service, upgrade costs, EV chargers, permits, and modern home power needs.

How do I know if I need an electrical panel upgrade?

Common signs include frequent breaker trips, flickering lights, no room for new circuits, older 100 amp service, a buzzing or warm panel, or plans to add major electrical equipment such as an EV charger, central air, or generator.

Is 200 amp service enough for most Nassau County homes?

For many modern homes, 200 amp service is a strong fit. It can provide better capacity for HVAC systems, EV chargers, kitchen appliances, home offices, and future renovations.

Do I need a panel upgrade for a Level 2 EV charger?

Not always, but many Level 2 EV chargers require a dedicated circuit and enough available panel capacity. Haines Electric can evaluate your current 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 the timeline depends on the scope of work, service size, permit requirements, inspection scheduling, and utility coordination.

Can I upgrade from 100 amp to 200 amp service?

Yes, many older homes upgrade from 100 amp to 200 amp service to support modern electrical demand. A licensed electrician should perform a load review and inspect your current equipment first.

Should I repair my panel or upgrade it?

A repair may be enough for a single bad breaker or localized issue. An upgrade may be recommended if the panel is outdated, overloaded, full, damaged, or unable to support your home’s electrical needs.

Will my power be off during the panel upgrade?

Yes, power is typically shut off temporarily while the work is performed. Haines Electric works efficiently to minimize disruption and restore safe power as quickly as possible.

200-Amp Electrical Panel Upgrades in Nassau County

If your home still operates on 100-amp service, upgrading to a 200-amp electrical panel can dramatically improve safety, performance, and future flexibility.

Today’s homes use more electricity than ever. Between central air conditioning, EV chargers, modern kitchen appliances, home offices, and smart home systems, older panels often struggle to keep up.

A 200-amp upgrade provides:

  • Increased electrical capacity for modern appliances

  • Reduced breaker trips and overload risk

  • Safer power distribution

  • Support for home additions or renovations

  • Higher resale value

Many Nassau County homeowners upgrade proactively before installing EV chargers, heat pumps, or completing kitchen remodels.

Our licensed master electricians handle the entire process, including:

  • Utility company coordination

  • Permit filing and inspections

  • Meter upgrades

  • Load calculations

  • Clean, code-compliant installation

If you’re planning upgrades or noticing warning signs, we can evaluate your current service and recommend the safest solution.

Experiencing partial power loss in your home? This is often a sign of an overloaded or failing electrical panel. Read our guide on what it means when half your house loses power and when a panel upgrade may be necessary.
