How Much Does an Electrical Panel Upgrade Cost in Arizona?

Typical Phoenix range: $2,600–$5,500 for a 100A to 200A main panel upgrade on a single-family home with an existing overhead service.

Upgrading to a 200 amp electrical panel in the Phoenix area typically costs $2,600 to $5,500. If the utility service drop, meter or grounding also has to be redone, it can reach $8,000. In Arizona the panel upgrade conversation is usually triggered by one of three things: adding solar, replacing an oversubscribed AC system, or a home inspection flagging a panel brand that no longer passes.

Materials

200A panel & breakers — $400–$1,200 per job. The panel itself is not the expensive part. Arc-fault and ground-fault breakers required by current code cost several times what a plain breaker does, and a full set adds up.
Meter socket / combo panel — $150–$600 per job. Often replaced at the same time. Some utilities require it when the service size changes.
Service entrance conductors & mast — $200–$900 per job. The wire from the utility connection into the panel. Larger service means larger conductors.
Grounding & bonding — $100–$400 per job. Older homes frequently have grounding that does not meet current code. This gets corrected as part of the upgrade whether or not it was in the original quote.
Whole-home surge protector — $150–$450 per job. Optional, and genuinely worthwhile in monsoon country where lightning-related surges are routine.

Labor & fees

Panel swap & circuit transfer — $1,200–$2,800 per job. One long day for a licensed electrician, with the power off for most of it. Every existing circuit gets moved and re-landed.
Utility coordination & disconnect — $200–$700 per job. APS, SRP or TEP has to pull and reset the meter. This is scheduling work as much as labor, and it is why the job cannot always happen on your preferred day.
Stucco & drywall repair — $150–$800 per job. The new panel rarely matches the old footprint exactly. Ask whether patching is included.
Permit & inspection — $150–$500 per job. Mandatory, and the utility will not reconnect at the new service size without a passed inspection.

Same job, three scopes

Panel swap, same amperage — $1,800–$3,200. Replacing a failed or obsolete panel without increasing service size. No utility upgrade needed.
100A to 200A upgrade — $2,600–$5,500. The standard job. New panel, new conductors, utility coordination, permit and inspection.
Upgrade with service relocation or underground — $5,500–$12,000. Moving the service point, or converting overhead to underground. Involves trenching and much more utility involvement.

Why Arizona is different

Air conditioning is the reason many Arizona homes run out of panel capacity. A larger or second AC system is a big continuous load, and a 100A panel that was fine in 1985 often is not now.
Rooftop solar almost always triggers this conversation. Interconnection rules limit how much solar you can back-feed through a given panel and bus rating.
Federal Pacific Stab-Lok and Zinsco panels turn up regularly in Arizona homes from the 1960s and 1970s. They are widely considered a fire risk, insurers increasingly refuse them, and they will be flagged in any home inspection.
Monsoon lightning makes whole-home surge protection more valuable here than in calmer climates, and it is cheapest to add while the panel is already open.
EV charging is the newest driver. A Level 2 charger is a substantial continuous load and frequently is the circuit that will not fit.

What it costs in your metro

Phoenix — $2,600–$5,500. The baseline. The deepest pool of licensed contractors in the state, so competitive bidding keeps prices closest to material cost plus a normal margin. Service territory splits between APS and SRP depending on the address, and their coordination processes and timelines differ. Your electrician should know which one you are on before quoting a schedule.
Mesa & the East Valley — $2,550–$5,400. Same supplier network as Phoenix with slightly lower overhead, and enough contractors that most jobs draw competing bids. Expect Phoenix pricing or a little under. Parts of Mesa are served by the city's own utility rather than APS or SRP, which changes the coordination process — confirm who your provider actually is.
Scottsdale — $3,050–$6,500. Higher labor rates, stricter HOA and design-review requirements on anything visible from the street, and a default expectation of upper-tier finishes. The permit and approval time alone adds cost. Panels on street-facing walls can fall under HOA appearance rules; screening or relocation may be required.
Tucson — $2,450–$5,150. Lower labor rates than the Valley and a slightly cheaper cost of doing business, though specialty materials are often trucked down from Phoenix. TEP is the utility here, with its own interconnection and meter-release process.
Flagstaff — $3,150–$6,700. A genuine freeze-thaw and snow-load climate, which changes what the code requires, plus a small contractor pool and haul distance on almost every material. The most expensive metro in the state for most work.
Prescott & the Quad Cities — $2,900–$6,150. Freezing winters, wildfire-related material requirements in many areas, and fewer contractors bidding than the Valley. Haul distance shows up on anything delivered by the truckload.
Yuma — $2,750–$5,850. The most extreme heat in the state drives equipment sizing and shortens summer working hours, and the local trade pool is thin enough that scheduling — not material — is often what costs you.

How to spot a quote that is off

A quote with no permit — the utility will not energize a new service without an inspection, so this is not a corner that can actually be cut.
No mention of who coordinates with the utility or how long that takes.
An unlicensed handyman offering to do it cheaply. This is service-entrance work at full utility voltage.
No line for arc-fault or ground-fault breakers, which current code requires for most circuits.
No stucco or drywall patch line on an exterior panel replacement.

Common questions

Do I need a 200 amp panel?

You need it if you are adding solar, an EV charger, or a second AC system, or if your current panel is full and you need more circuits. If none of those apply and the panel is a sound modern brand, a 100A or 125A service may still be perfectly adequate.

How long does the power stay off?

Typically six to ten hours on a standard upgrade, most of one working day. It depends more on when the utility can pull and reset the meter than on the electrician's speed.

My inspector flagged a Federal Pacific panel. Is that urgent?

Treat it as a priority rather than an emergency. The concern is that these breakers can fail to trip under fault conditions, and many insurers now decline coverage or require replacement. It is also very likely to come up again when you sell.

These are typical Arizona market ranges for the scope described, gathered to help you judge whether a quote is reasonable. They are not a quote, and they are not live pricing. Your own job can fall outside them for perfectly good reasons — get at least three written bids before deciding. Last reviewed August 2026.
