Your panel is the part of the house nobody thinks about until it can’t keep up. Add a new AC unit, a Level 2 EV charger, or a standby generator to a panel sized for a 1970s household, and something has to give. We assess what you actually have, what the new load needs, and whether an upgrade is genuinely required — with an upfront price either way.
What We Handle
- Panel replacement & upgrade — older or undersized service panels replaced with modern, correctly sized equipment.
- Fuse-box replacement — if you’re still on fuses, that’s a straightforward conversation about capacity and safety.
- Capacity assessment for added loads — AC, EV charger, generator, workshop, casita, pool equipment.
- Subpanels — adding a subpanel for a garage, addition, or detached structure.
- Code-compliant rewiring where needed — the panel work sometimes exposes upstream problems; we’ll show you rather than just tell you.
- Permitting & inspection — most panel work requires a City of Tucson permit and inspection, which we handle as part of the job.

Signs Your Panel Is the Real Problem
Frequent breaker trips under normal use, an older fuse-based panel, visible rust or scorching inside the enclosure, a panel that’s warm to the touch, or a panel that’s simply full with no space left for another circuit — those are the common signals. So is a plan: if an EV charger, a generator, or a new AC system is on your list, the panel question comes first, not last.
The other thing worth knowing is that not every “you need a new panel” recommendation is real. Sometimes the load calculation works out fine and the answer is a single circuit, not a $3,000 project. We do the calculation and show you the number.
Desert heat matters here too. Attic and garage temperatures in a Tucson summer are hard on connections and breakers, which is part of why a panel that was borderline five years ago may be failing now.

Pricing, Up Front
Tucson-area panel upgrades typically run about $1,190–$4,130 depending on panel size, service capacity, and how much of the surrounding wiring has to change. A straight swap at the same amperage sits low in that band; increasing service capacity, relocating the panel, or coordinating a utility disconnect moves it up.
General Tucson-market range for context, not an Eagle Electric rate card — we’ll confirm your exact price after the on-site assessment and before any work begins.

Panel Upgrade FAQ
How do I know if I need an upgrade?
Frequent breaker trips under normal use, an older fuse-based panel, a full panel with no room for new circuits, or plans to add an EV charger, generator, or new AC system are the common signs. We run the load calculation and show you the number rather than assuming.
Does this require a permit?
Yes — most panel work requires a City of Tucson permit and inspection. We handle that side of it as part of the job.
How long will my power be off?
A typical residential panel replacement means a planned outage for a good part of a day. We’ll give you the expected window before the day starts so you can plan around it.
Can you just add a subpanel instead?
Sometimes, and it’s often cheaper. Whether a subpanel solves it depends on your existing service capacity — that’s exactly what the assessment answers.
