How Long Does a Panel Upgrade Take in Phoenix? Permit to Power-On

How long a panel upgrade takes in Phoenix is one of the first things homeowners ask us, usually right after "what does it cost." The honest answer has two parts. The work itself, when the power is actually off, is part of one day in most cases. The calendar time around it depends on paperwork and scheduling that run through your city and your utility. Knowing which part is which helps you plan, and helps you spot a contractor who is guessing.

Two clocks: work day vs. calendar time

Think of a panel upgrade as two clocks running at different speeds:

• The work day. The utility disconnects, we pull the old equipment, set the new meter and panel, re-land and label every circuit, and handle grounding and the emergency disconnect where required. For a straightforward swap in the same location, the power is off for part of one day in most cases.
• The calendar. Everything before and after the work day: the estimate, the utility application, the city permit, the inspection, and the utility reconnect. Most of the waiting in a panel upgrade happens here, and much of it is outside any contractor's control.

When someone promises an exact date on the first phone call, they're promising something the city and the utility haven't agreed to yet. We give you a firm date once the utility confirms it.

The panel upgrade timeline, step by step

If you want the full picture of who is responsible at each step, our post on who does what in a Phoenix service upgrade breaks down the roles of the homeowner, the contractor, the city and the utility.

What makes a panel upgrade take longer

Most panel upgrades in the Valley follow the timeline above without surprises. These are the things that stretch it:

• Going bigger. Moving from 100 or 125 amps to 200 is the common job. Going to 400 amps usually means more utility review, and SRP requires shop drawings for every service rated 400 amps and above. Our SRP vs APS guide covers what each utility asks for.
• Moving the meter or panel. Replacing equipment in the same spot is simplest. Relocating it means the utility has to approve the new meter location first, and the wiring has to be extended to reach it.
• Overhead to underground (or a damaged mast). Any change to how the service reaches the house brings in the utility's design process and often trenching.
• Hidden problems. Corroded grounding, damaged branch wiring, or an old panel brand with melted connections can turn up once the cover comes off. We tell you before we change the plan.
• Inspection corrections. If the inspector asks for a change, we fix it and reschedule. That adds time, which is why we build to pass the first time.
• Utility schedules. Busy seasons and storm repairs pull utility crews away from routine work. That's the most common reason a simple job slips.

How long will my power be off?

This is the part that matters most to most families. For a same-location swap, plan on the power being off for part of one day. Power comes back when the utility reconnects. On some jobs the reconnect happens the same day as the work, and on others the meter stays out until the inspection clears and the utility returns. That depends on your utility, your city and the scope, so we confirm it with you before the work day, not after.

Plan ahead for the hours the power is off:

• Keep the fridge and freezer closed, and move medications that need refrigeration to a cooler.
• Tell us right away if anyone in the home uses medical equipment that needs power.
• Arrange for pets, especially in warm weather, since the AC will be off.
• Charge phones and laptops the night before if anyone works from home.
• Unlock gates and clear a path to the meter and panel so we can start on time.

Why fall and winter are a good time to schedule

In a Phoenix summer, a house with no AC gets hot fast, and working on a west-facing meter in afternoon sun is hard on people and equipment. Cooler months make the power-off day easier on your family and give everyone more flexibility if a step runs long. If you already know your panel needs replacing, getting it scheduled before next summer is the easiest way to avoid a no-AC day in July. Our panel upgrades page covers the signs it's time.

Panel upgrades in Chandler

Most of Chandler is in SRP territory, though your electric bill is the only reliable way to know your utility. Many Chandler homes were built in the 1980s, 1990s and 2000s, and a lot of them now need more capacity for EV chargers, pool equipment, bigger AC systems and home offices. In HOA neighborhoods, check whether your HOA wants to know about visible changes if the equipment is being relocated or a new disconnect is going on the outside wall.

Chandler's building department lets contractors request inspections online, by text or by phone, and requests made before midnight are scheduled for the next day. That helps keep the inspection step short. You can see how the city handles permits and inspections on Chandler's Building Safety page.

How to keep your panel upgrade on schedule

• Send photos up front. A picture of your electric bill, the meter and the inside of the panel tells us your utility, your current service size and what we're working with.
• Decide on future loads now. If an EV charger, pool, casita or solar is coming, tell us before we size the service. Changing the size after the application is filed starts parts of it over.
• Approve the scope in writing. Paperwork with the utility and the city starts once the scope is set.
• Be reachable on the work day. If we find something behind the cover, a quick answer keeps the day on track.
