Electrical Panel Upgrade: 7 Signs Your Florida Home Needs One
Your electrical panel sends power to every circuit in the house. When it is too small, too old or damaged, you start to see warning signs. This guide explains when an electrical panel upgrade makes sense and what the job involves in Florida.
We also cover how new equipment, such as a larger AC or an EV charger, changes the load on your panel. That way, you can plan ahead instead of finding out the hard way.
7 signs you need an electrical panel upgrade
- Breakers trip often, especially when the AC, dryer or microwave runs.
- Lights dim or flicker when a large appliance starts.
- The panel feels warm, buzzes or smells like burning plastic.
- You still have fuses instead of breakers.
- There are no open slots for new circuits.
- You are adding big equipment, like a new AC, a pool pump or an EV charger.
- The panel is decades old or shows rust and corrosion.
Warm panel or burning smell?
Treat it as an emergency. Turn off the main breaker only if it is safe to do so, and call a licensed electrician right away. For home safety basics, see the NFPA electrical safety resources.
Why Florida homes often need an electrical panel upgrade
Many South Florida homes were built with 100-amp service. At that time, one AC and a few appliances were the whole load. Today, however, homes run larger cooling systems, more electronics and sometimes an EV charger, so an older panel can run out of room.
Older panel brands
Some home insurers ask about the brand and age of your panel. For example, older Federal Pacific and Zinsco panels often come up in these questions. If you have one, a licensed electrician can inspect it and explain your options.
Salt air and humidity
Near the coast, moisture and salt can corrode panel parts over time. As a result, a panel that looks fine from the front may have problems behind the cover.
What an electrical panel upgrade involves
- An electrician reviews your current panel and the loads you plan to add.
- You receive a written quote that includes the permit.
- The permit is pulled and, if needed, the power company is scheduled.
- The old panel is replaced, circuits are labeled and the work is tested.
- An inspector signs off on the finished job.
Because a panel upgrade is permitted work, always use a licensed contractor. You can confirm any license on the Florida DBPR license lookup.
Planning a new AC? Check the panel first
A new or larger AC may need a dedicated circuit and a new disconnect. Since we handle both AC installation and electrical work, one team can plan the system and the power it needs together.

How long does a panel upgrade take?
The work itself usually takes most of a day. However, scheduling the permit and any power company visit can add time before and after.

Sometimes. A load calculation shows whether your panel has room or needs an upgrade first.
