If lights dim when your AC starts, or new appliances trip breakers, it may be time for a breaker box upgrade. A future-ready breaker box upgrade protects your home, powers modern loads, and meets Florida code. In storm-prone West Orlando, that means safer service, room to grow, and better surge protection. Below is a simple, homeowner-first guide to plan your upgrade with confidence and avoid costly rework.
Do You Really Need a Breaker Box Upgrade?
Modern homes pull far more power than they did ten or twenty years ago. EV chargers, heat pumps, pool equipment, home offices, and outdoor kitchens quickly outgrow older 60 or 100 amp services. If you notice any of the following, an upgrade is worth a serious look:
- Frequent nuisance trips when using the oven, dryer, or space heaters.
- Lights dim when large equipment starts, like AC or well pumps.
- Warm breakers, buzzing, or a panel that smells hot.
- Double-tapped breakers or a full panel with no room for new circuits.
- Aluminum branch circuits, old fuse boxes, or obsolete equipment.
- You plan to add an EV charger, hot tub, or whole-home generator.
In West Orlando neighborhoods like Clermont, Winter Garden, and The Villages, many homes built in the 1990s and early 2000s still run 100 amp service. That was fine then, but it can be tight once you add a Level 2 EV charger, induction range, or a heat pump water heater. Right-sizing your service now prevents overloads later and protects your investment in high-efficiency gear.
100A vs 200A vs 300A: Sizing for What Comes Next
Service size should be based on a load calculation, not guesswork. Your electrician will tally fixed appliances, HVAC, small-appliance circuits, and future plans. Here is a simple way to think about it:
- 100 amp service
- Often OK for smaller homes without electric heat or EVs.
- Little headroom for remodels or outdoor upgrades.
- 200 amp service
- Today’s common standard for single-family homes.
- Supports a Level 2 EV charger, electric range, dryer, and a heat pump system with margin.
- 300–400 amp service
- Larger homes or dual EVs, big pools, workshops, or full electrification.
Helpful benchmarks:
- A typical Level 2 EV charger needs a 40–60 amp, 240V circuit.
- Induction ranges often require 40–50 amps.
- Heat pump water heaters draw far less than resistance units, but still add to total load.
- Future solar plus battery storage may change how you distribute loads, even if utility service size stays the same.
Plan at least one step ahead. If you know a second EV, pool heat pump, or workshop is coming, it is cheaper to size the service and panel once than to rework later.
Florida and Code Requirements You Cannot Ignore
Electrical safety is not negotiable. Your upgrade must meet the National Electrical Code and local amendments. Key facts homeowners should know:
- Whole-home surge protective device required: The 2020 NEC requires a Type 1 or Type 2 surge protective device at dwelling-unit services (NEC 230.67). In Central Florida, with some of the highest lightning activity in the country, this is essential.
- Working space around panels: Maintain clear working space of at least 30 inches wide and 36 inches deep in front of the panel (NEC 110.26). No storage in this zone.
- Circuit labeling: All circuits must be legibly and durably labeled to match actual loads (NEC 408.4). Clear labeling speeds troubleshooting and future additions.
- AFCI and GFCI protection: Arc-fault protection is required for many habitable rooms (NEC 210.12). GFCI protection is required in locations like kitchens, garages, outdoors, and bathrooms (NEC 210.8). Many situations call for dual-function breakers.
- Permits and inspections: Service upgrades require permits and final inspection. Your contractor should handle this.
- Utility coordination: Upgrades often require scheduling with your utility to disconnect and reconnect service. In West Orlando this may involve Duke Energy, OUC, or SECO Energy depending on the address.
Del-Air handles all permitting, scheduling, and code compliance so you do not have to navigate the details.
What Happens During a Professional Panel and Service Upgrade
Knowing the process helps you plan the day and reduce downtime. A typical upgrade looks like this:
- Load calculation and scope
- We document your current loads and planned additions, then recommend the right service size and panel configuration.
- Proposal and parts selection
- We specify panel brand, breaker types, whole-home surge protection, grounding, and any subpanels or generator interlocks.
- Permitting and utility scheduling
- We submit permit applications, coordinate with your utility for a safe disconnect, and schedule inspections.
- Site prep and safety
- Power is turned off. We protect floors, verify clearances, and set up work lighting.
- Panel replacement and service upgrade
- We remove obsolete equipment, set the new panel, upgrade the meter base and conductors if needed, and install required bonding and grounding.
- Breaker and circuit migration
- Circuits are moved, neatly dressed, and labeled. We install AFCI or dual-function breakers where code requires.
- Surge and protection devices
- We install the whole-home surge protector at the service and test it.
- Inspection and re-energization
- After inspection, the utility restores power. We verify voltage, breaker torque, and device operation.
- Walkthrough and documentation
- We review labeling, show you the surge indicator lights, and provide permits, inspection sign-offs, and warranty details.
Most straightforward upgrades take one working day once utility scheduling aligns. Complex jobs with meter relocations or trenching may take longer.
Cost Ranges and What Drives Them in West Orlando
Every home is different, but these typical ranges can help with budgeting:
- 200 amp panel and service upgrade: About $2,500 to $5,500 depending on panel brand, conductor lengths, meter base, and grounding corrections.
- 300–400 amp upgrades or split-bus configurations: Often $5,000 to $9,000 due to larger service equipment and potential utility work.
- Whole-home surge protective device: Commonly $300 to $700 installed, brand dependent.
- AFCI or dual-function breakers: Typically $40 to $90 per breaker, quantity varies by home and code triggers.
- Meter base relocation or service mast work: Costs vary by structure and utility requirements.
Price is not only about the panel. Permitting, utility coordination, grounding upgrades, and inspection support all contribute to a safe, compliant job. Cheaper bids that skip these steps can lead to failed inspections, rework, or safety hazards.
Breaker Choices, Smart Panels, and Future-Proof Options
Your panel is the backbone of the system, but breaker choice matters too:
- Standard thermal-magnetic breakers: Handle overcurrent and short circuits.
- AFCI breakers: Sense arcing faults common with damaged cords or staples through wiring. Required in many habitable rooms.
- GFCI breakers: Protect against shock in wet or damp areas like baths, garages, and outdoors.
- Dual-function breakers: Combine AFCI and GFCI in one unit where both are required.
- Whole-home surge protection: Intercepts high-energy transients from the grid and lightning.
Smart options to consider:
- Load-monitoring modules or smart panels that show real-time circuit usage in an app.
- Solar- and battery-ready panels with space for backup subpanels or generator interlocks.
- EV-ready conduit paths from panel to garage, even if you are not installing the charger today.
These features simplify troubleshooting, reduce nuisance trips, and make future projects easier.
DIY vs Licensed Electrician: Why Permits Matter
Service equipment is not a DIY arena. Mistakes can arc, shock, or fail inspections. Reasons to use a licensed electrician:
- Proper load calculations prevent undersizing.
- Correct grounding and bonding protect people and electronics.
- Permits and inspections document safety and code compliance for insurance and resale.
- Utility-approved meter bases and service conductors avoid delays and callbacks.
In Florida, upgrading service without permits can cause insurance issues or trouble at closing. A documented, inspected upgrade protects your investment.
How to Prepare Your Home for Upgrade Day
Simple prep helps the job run fast and clean:
- Clear a 3 ft by 3 ft area in front of the panel and ensure a 30 inch wide zone is free of storage.
- Move vehicles so our crew can access the meter, panel, and garage.
- Plan for a full-day outage. Charge devices and keep refrigerators closed.
- Inform alarm and internet providers of the planned outage if needed.
- Walk through future plans with your electrician so we route conduit and leave panel space accordingly.
If your panel is outdoors, trim shrubs and remove wall decor on the inside opposite the panel to avoid accidental damage.
Lightning, Surges, and Central Florida Reality
Central Florida sees frequent lightning and utility switching events. Sensitive electronics in HVAC systems, refrigerators, and smart home devices can be damaged by even small surges. A few points to consider:
- A code-required service-level surge protector is a strong first line of defense.
- Point-of-use surge strips add another layer for computers and entertainment.
- Proper grounding and bonding make surge devices far more effective.
Together, these measures help protect appliances and electronics during our intense summer storms.

Safety Red Flags That Cannot Wait
Call a licensed electrician promptly if you notice any of these:
- Burnt or melted bus bars, scorch marks, or a smoky odor at the panel.
- Breakers that will not reset, or that trip immediately.
- Corrosion in outdoor panels, especially near the coast or pool equipment.
- Warm breakers to the touch or a humming panel under light load.
These conditions indicate hazards that need immediate attention.
Planning Add-Ons During the Upgrade Saves Money
Bundling upgrades during a service change often saves time and return trips:
- Add a garage subpanel and conduit for one or two future EV chargers.
- Install a generator interlock or set up a backup subpanel for critical loads.
- Run a 240V circuit to a future workshop, spa, or outdoor kitchen.
- Upgrade smoke and carbon monoxide detectors on dedicated circuits.
Doing this work while the panel is open can lower total cost and minimize disruption.
Frequently Asked Questions
How long does a typical breaker box and service upgrade take?
Most straightforward upgrades take one working day once permits and utility scheduling are in place. Complex projects with relocations or trenching can take longer.
Do I need 200 amps if I am adding one EV charger?
Often yes. A 40–60 amp Level 2 charger plus existing loads can strain 100 amp service. A load calculation will confirm the right size for your home.
Is whole-home surge protection really required in Florida?
Yes. The 2020 NEC requires surge protection at dwelling-unit services. It is especially valuable in Central Florida due to frequent lightning and utility switching.
Will I be without power during the upgrade?
Yes. Expect a full-day outage. We coordinate with your utility to minimize downtime and restore service immediately after inspection and approval.
Can I keep my existing circuits and just replace the panel?
Often yes. We migrate compliant circuits, replace any damaged conductors, add AFCI or GFCI protection where required, and label all circuits accurately.
