Do You Need an Electrical Panel Upgrade? 7 Signs for Katy and Houston Homes

Your electrical panel decides how much power the house can use safely and how well it is protected when something goes wrong. Many homes in Memorial, Spring Branch, Nottingham Forest and the older parts of Katy were built in the 1960s through the 1980s, and plenty of them still have 100- or 125-amp service. That was enough at the time. It is not always enough for central air, an electric heat pump, a pool, a home office, and now an EV charger or a standby generator.

Here are seven signs a panel upgrade is worth considering, followed by what the work actually involves.

7 signs you may need a panel upgrade

1. You have 100-amp service or less

The amperage is printed on the main breaker at the top of the panel. A 100-amp panel can run a modest home, but it leaves little room for the loads people add today. Most homes built in the last couple of decades have 200-amp service.

2. Breakers trip often, or there is no room for new circuits

Frequent trips under normal use, or a panel so full that every new circuit needs a tandem breaker squeezed in, both say the panel has run out of capacity. If trips are limited to one circuit, start with our electrical repair service.

3. You are adding a big new load

An EV charger, a heat pump replacing a gas furnace, a pool or spa, an addition, a shop in the garage or a standby generator can each push an older panel past what it can safely supply. A load calculation tells us whether the existing service can carry it.

4. The panel is warm, buzzing or scorched

A panel should never feel hot, smell like burning plastic or make a crackling sound. Discolored breakers or melted insulation mean a connection is overheating. Treat this as urgent.

5. Rust or corrosion

Gulf Coast humidity is hard on outdoor panels and meter bases. Rust inside a panel, water stains, or corroded breaker connections are a reason to replace it, not just clean it.

6. It is a Federal Pacific, Zinsco or fuse panel

Federal Pacific Stab-Lok and Zinsco panels were common in homes built from the 1950s into the 1980s, and both have a long record of breakers that may not trip when they should. Fuse boxes predate modern protection entirely. Insurers and home inspectors often flag all three.

7. Lights dim when big appliances start

Lights that dip when the AC compressor or dryer starts can point to an undersized service, a loose connection or a utility-side problem. It is worth having an electrician find out which.

Panel replacement vs. service upgrade

A panel replacement swaps an old or unsafe panel for a new one at the same amperage. A service upgrade increases the amperage, for example from 100 to 200 amps, which usually means a new panel, meter base and service conductors, plus coordination with the utility (CenterPoint for most of the Houston area) to disconnect and reconnect power. Which one you need depends on the load calculation, not on the age of the panel alone.

Start with a load calculation

Before recommending an upgrade, we calculate your home's electrical load the way the electrical code does: square footage, appliances, HVAC equipment, and anything you plan to add. Sometimes the existing service has room to spare. Sometimes a load management device, which pauses an EV charger when the house is drawing heavily, avoids an upgrade altogether. Sometimes the upgrade is the right call. You will know which before you spend anything.

What the day looks like

• We pull the permit where your city requires one and schedule the utility disconnect.
• Power to the house is off while the work is done, usually for most of a day.
• We install the new panel and breakers, label every circuit, and correct problems we find along the way, like double-tapped breakers or missing bonding.
• The work is inspected where required, and the utility restores power.

It is also the best time to add a whole-house surge protector, which mounts at the panel and helps protect HVAC control boards and electronics from the surges that come with Houston storms.

Frequently asked questions

How long does a panel upgrade take?

The on-site work is usually done in a day. Scheduling the permit, the utility disconnect and the inspection takes longer than the work itself.

Do I need a permit?

Inside city limits, including Houston, Katy and Sugar Land, a permit and inspection are typically required. In unincorporated areas the work still has to meet code and be done by a licensed electrical contractor. We handle the paperwork either way.

Can I add an EV charger without upgrading my panel?

Often, yes. Many 200-amp homes have room for a charger, and a load management device can make it work on smaller services. A load calculation tells you for certain. See EV charger installation.

Is my old panel a fire risk?

Any panel with overheating connections, corrosion or breakers that do not trip is a risk. Federal Pacific and Zinsco panels deserve an inspection even if they seem to work fine.
