Electrical Panel Upgrades in Longwood

What panel upgrades involve, what to check before hiring, and how 10 Longwood electricians compare on this work.

Electrical panel upgrades in Longwood

A panel upgrade means swapping out your home's electrical panel (also called a breaker box or load center) for one with more capacity, modern breakers, and proper safety features. In Longwood, this usually comes up for a few reasons: an older home still running a 60 or 100-amp fused panel that can't support central AC, an EV charger, or a kitchen remodel, a panel made by a brand with known recall or fire-risk issues (Federal Pacific and some Zinsco models are the common culprits here), or an insurer requiring an upgrade before renewing a policy on an older house.

We list 10 electricians in Longwood who do this work. Before hiring, ask whether they'll pull a permit (panel work almost always requires one), how they size the new panel for your actual and future load, and whether they carry the license and insurance required for this kind of work in Florida. A good electrician will also check your grounding and bonding, not just swap the box.

Our scoring weighs licensing, verified reviews, response time, and how consistently a company follows through on quoted work, so you're not just picking a name off a list.

Steve's crew shows up when they say they will, diagnoses problems thoroughly, and leaves your home cleaner than they found it. Reviewers consistently mention Carlos, Steve, Joe, and Daniel by name as electricians who take time to explain what they are doing and why, from outlet repairs to EV charger installs. One reviewer noted the bill surprised them, but still rated the work highly enough to consider returning. The business owner Steve is visible in the field and in customer interactions, which reviewers notice and respect. Surge protection, panel diagnostics after storms, and receptacle work all get specific praise. They handle residential work with care for your property and offer clear options when you need choices.

Most customers praise Frank Gay's punctuality, named technicians (Antonio Diaz, Hamzah, Dwayne, Thomas Gold, Claudius Harvey), and upfront explanations. However, recurring complaints target their $90 diagnostic fee model, unresolved issues requiring repeat visits, and a handful of customers reporting major work (AC repairs, duct cleaning) left incomplete or damaged, with poor follow-up when problems resurface.

Strong individual technicians (Sam, Eric, Ray, Max, Andrew named positively) respond fast and fix issues quickly, earning five-star marks. The company's sales practices and follow-up systems falter repeatedly: customers report inflated quotes without clear breakdowns, missed appointments without calls, unresolved warranty disputes, and units still broken after multiple visits. The contrast between field staff competence and organizational reliability shapes a divided experience.

When JD Electrical does the work, reviewers praise the speed and honesty, with Jim and his technicians like Dave, Ray, Steve, and Phillip solving complex problems quickly without padding invoices. However, a volatile pattern of no-shows, missed appointments, and at least one dangerous installation mess that the company refused to address creates serious trust issues for some customers.

Common questions about electrical panel upgrades

How much does a panel upgrade cost in Longwood?
Most residential upgrades to a 200-amp panel run roughly $1,800 to $4,000 depending on panel size, whether a service line upgrade from the utility is also needed, and how much rewiring or code-bringing-up-to-date is involved. Older homes with outdated wiring or a full service mast replacement will run toward the higher end.
How do I know if my panel needs to be upgraded?
Common signs are breakers that trip repeatedly, a panel rated under 100 amps, visible rust or burn marks, a Federal Pacific or Zinsco panel, or an inability to add circuits for new appliances, an EV charger, or a home addition.
How long does a panel upgrade take?
A straightforward swap usually takes one day, sometimes with a brief power shutoff arranged with the utility. Jobs that also need a new service line, meter can, or grounding work can stretch to two or three days.
What should I check to judge the quality of the work?
Confirm the electrician pulled a permit and scheduled the required inspection, ask to see the panel's amperage and brand before work starts, and get the warranty terms in writing. A licensed electrician should also explain how they're sizing the panel for your home's actual load, not just installing the biggest box available.
