If your lights dim when appliances start, or breakers trip often, it is time to consider an upgrade from 100 amp to 200 amp service. This guide explains when a 200 amp service makes sense, how the process works, what it costs, and how Del‑Air keeps everything code‑compliant. Expect a clear plan, free estimates on replacements, and same‑day availability when you need it.
Why Upgrade from 100 Amp to 200 Amp Service
A 100 amp service was common in mid‑century homes. Modern homes use more power. EV chargers, larger HVAC systems, heat pumps, induction ranges, and home offices push demand beyond what a 100 amp panel comfortably supports.
Benefits of a 200 amp upgrade:
- Capacity for today and the future
- Support for EV chargers, hot tubs, solar interconnects, and high‑efficiency HVAC.
- Room to add circuits without daisy‑chaining or overloading.
- Fewer nuisance trips and voltage dips
- Right‑sized breaker configuration and balanced loads reduce dimming when appliances start.
- Improved safety and resale value
- New panels support AFCI/GFCI protection and whole‑home surge protection.
- Easier integration of smart home devices
- Smart panels and energy monitoring reveal real usage and let you manage loads.

Signs Your Home Has Outgrown 100 Amps
You do not need to guess. Look for these real‑world triggers:
- Frequent breaker trips when the AC and oven run together.
- Dimming or flickering when a large appliance starts.
- EV charger plans but no spare capacity in the panel.
- Warm breakers, buzzing, or a panel that is rusted or obsolete.
- Too few spaces, or tandem breakers used only to make room.
Local insight: Central Florida homes often add pool pumps, spas, and whole‑home dehumidifiers. These loads stack up quickly on a 100 amp service.

What a 200 Amp Service Upgrade Includes
A true service upgrade is more than swapping a box. It is a system update designed around how you use power today.
What Del‑Air covers during a typical upgrade:
- Home electrical assessment
- We review your current panel, breaker sizing, and overall load to match your actual usage.
- Clear, upfront plan
- You receive a walk‑through of the recommended panel size, breaker configuration, and any additional components for a clean, safe installation.
- Permitting and inspections
- Service upgrades require permits and utility coordination. We manage the process and schedule inspections.
- Equipment and materials
- New 200 amp rated load center, main breaker, service entrance conductors, meter equipment as needed, grounding and bonding updates, and labeling.
- Optional add‑ons
- Whole‑home surge protector, AFCI/GFCI updates, EV‑ready circuits, subpanel or smart panel upgrades, and generator transfer switch prep.
- Final safety checks
- We verify torque, labeling, grounding/bonding, GEC terminations, and breaker operation before restoring full service.
Hard fact for safety: The National Electrical Code requires working clearance of 30 inches wide, 36 inches deep, and 6 feet 6 inches high in front of panels. We ensure this space is maintained.
Cost, Timeline, and What Drives Price
Every home is unique. Pricing depends on:
- Service entrance path and meter location.
- Need for new grounding electrodes or bonding upgrades.
- Condition of existing wiring and panel brand.
- Utility coordination and mast or meter enclosure changes.
- Add‑ons like surge protection, EV circuits, or subpanels.
Typical timeline:
- Assessment and estimate: same day in most cases.
- Permitting: usually a few business days depending on jurisdiction.
- Installation: often completed in one day, with power off for several hours.
- Inspection and wrap‑up: typically within 24 to 72 hours after install.

Technical Essentials Homeowners Ask About
Understanding a few technical points helps you make confident decisions.
- Service conductors and panel rating
- A 200 amp service uses conductors sized per NEC 310.12, such as 4/0 aluminum or 2/0 copper for typical dwellings. Your exact setup depends on run and conditions.
- Grounding and bonding
- We confirm the grounding electrode system, water and gas bonding where required, and proper connections at the neutral and ground bars.
- Breaker selection and labeling
- AFCI and GFCI protection are applied to required circuits. Clear labels make future work safer and faster.
- Load balancing
- We distribute high‑demand appliances across legs to reduce nuisance trips and dimming.
- Space for the future
- We size panels with extra spaces for remodels, EVs, and outdoor equipment.
Hard fact for value: Florida is among the top states for lightning, and Central Florida experiences frequent severe storms. Whole‑home surge protection paired with your 200 amp panel helps protect HVAC systems, refrigerators, and electronics from transient surges.
EV Chargers, Heat Pumps, and Smart Homes: Why 200 Amps Helps
- EV Chargers: Level 2 chargers often need a dedicated 40 to 60 amp circuit. Many 100 amp homes cannot spare that much capacity without shedding other loads.
- Heat Pumps and High‑Efficiency HVAC: Modern systems may include electric heat strips or variable speed compressors that benefit from stable voltage and available capacity.
- Smart Panels and Load Management: A 200 amp backbone supports smart panels and energy monitors, helping you schedule heavy loads and view consumption in an app.
- Solar and Battery Readiness: A properly sized main service and panel space make future solar or battery backup tie‑ins cleaner and more affordable.

Frequently Asked Questions
How do I know if I need a 200 amp upgrade?
If breakers trip with everyday use, lights dim during appliance start‑up, or you plan to add an EV charger or spa, you likely need more capacity. A load calculation confirms it.
Will my power be off during the upgrade?
Yes, power is shut off during panel changeover. Most projects finish the same day, with several hours of downtime. We coordinate with the utility to minimize disruption.
Do I need a permit for a service upgrade?
Yes. Service upgrades require permits and inspections. We manage permit applications, inspections, and utility coordination on your behalf.
Can I add an EV charger with a 100 amp service?
Sometimes, using load management. In many cases a 200 amp upgrade is the cleanest path. We evaluate options and provide a clear plan and price.
Should I install surge protection with my new panel?
Yes. Central Florida storms create frequent surges. A whole‑home surge protector helps protect HVAC, appliances, and electronics.
