Panel upgrades
Electrical panel upgrades for heat pump and EV load in Port St. Lucie
A panel upgrade is a capacity decision. Older east-side Port St. Lucie, Fort Pierce, and Lakewood Park homes often outgrow their service once a heat pump, pool equipment, and a modern kitchen share it. Newer Tradition and Verano panels start stronger until an EV charger or remodel asks for more. Because Port St Lucie Air Conditioning & Electric handles both the AC and the electrical, we size the panel around the equipment you actually run.
What we’d tell you first
Plain notes, the way a tech would say them on the phone. Then call or book if you want someone at the house.

Capacity before cosmetics
A new panel cover does not add amps. We measure load and say whether you need a service upgrade, a subpanel, or just a cleaner breaker layout.

Plan the outage
A service change needs a real power-off window. Ask us how long before work day so food and medical devices are covered.

EV and heat pump loads
Those two additions are the usual reason a Port St. Lucie panel feels tight. Bring the charger or equipment specs when you book.
When a panel upgrade is the honest call
We open the cover and look at the load, wire sizes, breaker condition, double taps, and signs of heat. A warm cover, a buzzing bus, scorch marks, or breakers that will not hold after a storm mean it is time to stop guessing and measure.
Sometimes the answer is not a full service change. A new dedicated circuit, a subpanel for a garage, or a load management device may solve the problem for less. You hear about those options when they are safe and real.
- A new heat pump or larger system needs a heavier circuit
- An EV charger is planned and the panel is already crowded
- A remodel adds kitchen, laundry, pool, or workshop loads
- A home inspector or insurer flagged the panel
- Breakers trip repeatedly and it is not one bad appliance
- Lights dim when the AC compressor starts
Heat pumps and the panel
Every heat pump has a nameplate that lists the minimum circuit size and the largest breaker it can use. A replacement system with different specifications may need a new breaker and wire, not just a reconnection to the old circuit. Many air handlers here also have electric heat strips for backup heat, and those can draw more power than the outdoor unit on a cold morning.
When we replace or add equipment, we check the outdoor circuit, the air handler circuit, and the disconnect together. If the panel cannot safely carry the new system, we tell you before the installation is scheduled so the electrical and the AC work land in the right order.
EV chargers and long, steady loads
A Level 2 EV charger is a continuous load, and the electrical code requires the circuit to be sized with extra margin for that. It often runs overnight, at the same time the heat pump is working to keep the house cool. Add a pool pump, a water heater, and a dryer, and a panel that looked fine on paper can be close to its limit.
We do a load calculation based on your actual appliances and the charger you plan to buy. Then we tell you whether a dedicated circuit is enough, whether a load management device can share capacity safely, or whether the service needs an upgrade. See EV charger rough-in for the circuit work itself.
Older panels in Port St. Lucie and Fort Pierce
Many older homes still have their original 100-amp or smaller service. Some have panel brands that home inspectors and insurance companies regularly flag. Others have aluminum branch wiring, crowded breakers, or corrosion in the meter can, especially near the water in Fort Pierce.
We will tell you what we see and why it matters. If the panel can be repaired safely, we say so. If it should be replaced, we explain the scope and the outage window before any work starts.
Storm season and surge protection
Lightning and power surges are common on the Treasure Coast from late spring through fall. A surge can damage the AC contactor, control boards, and electronics throughout the house. A whole-home surge protective device at the panel adds a layer of protection and is worth discussing during an upgrade.
If your panel was damaged in a storm, or water got into it, leave the main breaker off if it is safe to reach and call. Do not reset breakers in a wet panel.
What the upgrade includes
We confirm what the utility service can support, pull the permit the City of Port St. Lucie, City of Fort Pierce, or St. Lucie County requires, and coordinate with the utility for the address, which is FPL for most of Port St. Lucie and often the Fort Pierce Utilities Authority inside Fort Pierce. The changeover is scheduled so the house is without power only as long as the work needs.
Port St Lucie Air Conditioning & Electric is Licensed & Insured for residential work. No license number is printed on this site until it is confirmed. We stay residential and say when a job is outside what we take on.
How to schedule a panel evaluation
Call (772) 539-4865 or book online. Tell us what you want to add, such as a heat pump, EV charger, pool equipment, or a remodel, and the approximate age of the house. A photo of the panel label helps, but it is not required.
Questions we’d answer on the phone
The short version before anyone is standing in the yard.
Do I always need a 200-amp panel?
No. We size from measured load and what you plan to add. Some homes need 200 amps. Others need a cleaner 100-amp panel, a subpanel for a garage, or a load management device.
Will my panel handle a new heat pump and an EV charger?
It depends on the existing load and the equipment specifications. We do a load calculation and tell you before you buy either one.
Will the house lose power all day?
A service change needs a planned outage. We tell you the window before work starts and coordinate with the utility when their disconnect is required.
My insurance company flagged my panel. What should I do?
Book an evaluation. We will look at the panel, tell you whether it can be repaired or should be replaced, and explain the scope in writing.
