Electrical Service Upgrade in Davenport & Central Florida
If your home’s electrical system is struggling to keep up with modern demand, an electrical service upgrade may be the safest and most effective solution. Upgrading your service increases the total power capacity delivered from the utility company to your home — most commonly from 100 amps to 200 amps, and in some cases to 400 amps.
At JCM Home Services, we provide professional service entrance upgrades throughout Davenport and Central Florida, helping homeowners improve electrical capacity, safety, and code compliance for today’s appliances and future upgrades.
What Is an Electrical Service Upgrade?
An electrical service upgrade increases the total amperage your home can safely handle. It goes beyond replacing breakers and focuses on the equipment that brings power from the utility into your home.
Depending on your setup, a service upgrade may include updates to:
- Main breaker panel
- Service entrance conductors
- Meter base
- Service mast/weatherhead (overhead service)
- Main disconnect
- Grounding and bonding systems
- Utility coordination for disconnect/reconnect

Service Upgrade vs. Panel Upgrade
Homeowners often use these terms interchangeably, but they are not always the same.
A panel upgrade replaces the breaker panel inside the home and may not increase overall electrical capacity.
A service upgrade increases the amperage coming from the utility company (such as 100A to 200A) and may include panel replacement along with meter, mast, grounding, and bonding updates.
Signs You May Need a 200 Amp Service Upgrade
If your system is nearing capacity, you may notice:
- Repeated breaker trips
- Flickering or dimming lights
- Buzzing from the panel
- Warm outlets or switch plates
- Limited room for new circuits
- Heavy reliance on power strips or extension cords
You may also need a service upgrade when adding higher-demand equipment such as:
- EV charger installation
- Whole-home generator
- Hot tub or pool equipment
- Electric range or dryer
- Upgraded HVAC or heat pump system
- Workshop equipment
- Major home renovations or additions
When 200 Amps May Not Be Enough
Larger homes, multi-family properties, or homes with multiple high-demand electrical loads may require:
- 400 amp service
- Dual 200 amp panels
- Subpanels for detached garages or buildings
JCM Home Services performs a load evaluation and recommends the right capacity for your current needs and future plans — without overselling.
What to Expect During a Service Entrance Upgrade
Electrical service upgrades typically begin with a load calculation and system evaluation. From there, permitting is handled and coordination with the utility company is arranged for a scheduled disconnect.
After the upgraded equipment is installed and inspected for code compliance, the utility company restores service.
In most cases, power is interrupted for approximately 4–8 hours depending on the scope of work and inspection timing.
Electrical Service Upgrade Cost: What Affects Pricing?
Pricing depends on the scope of the upgrade and site conditions. Common factors include:
- Overhead vs. underground service
- Condition of existing wiring
- Meter base replacement requirements
- Service mast replacement needs
- Grounding and bonding updates
- Panel relocation requirements
- Moving from 100A to 200A or 400A service

Electrical Panel Upgrade FAQs
Do I need to upgrade my panel when upgrading my electrical service?
In many cases, yes. If your existing breaker panel is not rated to handle higher amperage, it must be replaced to support a 200 amp or 400 amp service upgrade safely. JCM Home Services evaluates your current equipment and ensures every component is properly sized and code-conscious before increasing capacity.
How long will my power be turned off during a service upgrade?
Most electrical service upgrades are completed in a single day. Power is typically shut off for several hours while the new service components are installed, inspected, and approved. JCM Home Services coordinates scheduling with the utility company to minimize downtime and restore power as quickly and safely as possible.
Will I need to rewire my entire home?
No. A service upgrade increases the total electrical capacity entering your home — it does not automatically require whole-home rewiring. Unless existing wiring is unsafe or damaged, your interior circuits generally remain in place. JCM Home Services will let you know if any additional improvements are recommended.
Can I install an EV charger without upgrading my electrical service?
Sometimes. It depends on your current load calculation and available panel capacity.
Before recommending any upgrades, JCM Home Services performs a detailed evaluation to determine whether your existing system can safely support an EV charger installation or if a service upgrade would provide better long-term reliability.
Will upgrading my service stop breakers from tripping?
If breaker trips are caused by an overloaded system that lacks sufficient amperage, increasing your service capacity may resolve the issue. However, if trips are due to wiring faults, short circuits, or failing breakers, additional repairs may be necessary.
JCM Home Services can diagnose the root cause and recommend the appropriate solution.
Can I perform a DIY electrical panel or service upgrade?
Attempting a DIY panel or service upgrade is extremely dangerous. Electrical service work involves live utility connections, high-voltage conductors, permitting, inspections, and strict code requirements.
Mistakes can result in severe injury, fire hazards, failed inspections, or costly repairs. JCM Home Services handles service upgrades safely, coordinates with the utility company, and helps ensure everything meets current electrical standards.
What are the risks of not upgrading an outdated electrical service?
An undersized or aging electrical service can lead to overloaded circuits, frequent breaker trips, overheating conductors, and increased fire risk. As homes add EV chargers, electric appliances, and modern HVAC systems, older 100 amp services often operate beyond their intended capacity.
Delaying an upgrade can result in unreliable power, equipment damage, and safety hazards. JCM Home Services evaluates your system and helps you determine whether upgrading now can help prevent bigger problems later.
