Electrical Panel Upgrades in Longwood

What panel upgrades involve, what to check before hiring, and how to compare the 7 Longwood electricians who do this work.

A panel upgrade means swapping out your home's main electrical panel, and often the breakers and sometimes the meter base, for one with more capacity or better safety features. In Longwood, this usually comes up for a few reasons: an older home still running a 60 or 100-amp panel that can't handle modern appliance loads, a panel with a brand known for failing breakers (Federal Pacific and some Zinsco models are common culprits), plans to add a pool, EV charger, or central AC, or an insurance company asking for it before renewing a policy on an older house.

The work itself involves the electrician cutting power to the house, disconnecting the old panel, mounting the new one, re-terminating every circuit, and coordinating an inspection with Seminole County or the local building department. A straightforward upgrade often takes a full day, sometimes two if the service line or grounding needs work too.

When comparing the 7 electricians listed here, look for a permit pull on every panel job (not optional, this is inspected work), a clear written quote that names the panel brand and amperage, and a licensed electrician on site rather than an unlicensed helper doing the termination work. Our ranking at the best electricians in Longwood weighs licensing, review consistency, and response time, and the scoring approach is laid out in full on our methodology page.

Frank Gay's best work comes from individual technicians who diagnose quickly, explain steps clearly, and finish jobs the same day. Yet the company struggles with follow-through: customers report warranty denials after promises were made, subscription charges buried in quotes, and delayed responses when something goes wrong. Electricians and plumbers like Jose, Alex, and Sergio earn consistent praise for skill and politeness. The real friction emerges after the sale-when warranty claims stall, billing departments prove unreachable, and management does not return calls about problems they caused.

Techs like Sam, Eric, Ray, and Max earn consistent praise for speed and expertise-appointments same-day, jobs finished in hours, customers sign up for memberships. The catch: quotes jump thousands of dollars above market rate with bundled add-ons reviewers never asked for, calls go unreturned, and no-shows happen even under their 24/7 guarantee. One customer waited a week for a follow-up that never came; another had three visits in six days that failed to fix the unit, then a promised fourth visit simply didn't happen.

Most jobs come back on time and diagnosed quickly, with technicians like Kevin and Michael earning specific praise for patience and thoroughness.

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 100 to 200-amp upgrades on a standard single-family home run somewhere between $1,800 and $4,500, depending on panel size, whether the meter base and service line also need replacing, and how much rewiring the inspector requires. Older homes with aluminum wiring or knob-and-tube runs tend toward the higher end because more has to be brought up to code at the same time.
How often does a panel need to be replaced?
A well-maintained panel from a reputable manufacturer can last 25 to 40 years. You don't replace on a schedule so much as by symptoms: breakers that won't reset, warm spots on the panel cover, flickering lights under load, or a known problem brand like Federal Pacific or older Zinsco, which many Longwood electricians recommend swapping regardless of age.
What should I expect on the day of the upgrade?
Power to the house goes off for most of the workday, so plan around that if you work from home or rely on medical equipment. The electrician disconnects the meter (sometimes with the utility present), installs the new panel and breakers, and the job isn't finished until it passes a county inspection, which may happen the same day or a few days later.
How can I judge whether a quote is fair?
Ask what amperage and brand of panel is being installed, whether the price includes the permit and inspection, and whether grounding and bonding will be brought up to current code. A quote that skips the permit or is vague about panel specs is the biggest red flag, more than price alone.
