We have repaired, upgraded, and replaced panels across the Valley since 2001, and finding the cause before recommending the fix is how we have always worked.

Reno Blomquist has been doing electrical work since 1983, and panels are where that experience shows most. We diagnose the actual cause before recommending any repair, we pull the permits and coordinate with the city and SRP or APS, and we back the work with a one-year warranty on labor and materials.

Call day or night. A real person answers, and if your panel problem is actually an emergency, an electrician is typically on the way within two hours.

The Three Problems We See Most

The Three Panel Problems
We See Most Across the Valley

Most panel calls we run come down to one of three stories. Knowing which one is yours changes everything about the right fix.

01
PROBLEM 01

The panel that cannot keep up anymore

Whole-house flickering and random power outages are the two warning signs we tell every homeowner never to ignore. Older Valley homes were wired for a fraction of what a modern household draws: two refrigerators, a garage freezer, a pool pump, and an air conditioner running ten hours straight in July. The panel is not broken exactly. It is exhausted. Fatigued and worn main bus bars are what we find inside more than anything else, and they are the deciding factor in our repair-versus-replace call.

02
PROBLEM 02

The breaker that will not reset or will not stop tripping

‘I cannot reset my breaker’ tops the call log in any given Mesa week. A breaker that keeps tripping is protecting you from something: an overloaded circuit, a fault, or a failing breaker body itself. The dangerous shortcut is installing a bigger breaker to stop the nuisance, which we find in panels all over the Valley. That does not fix the problem. It removes the protection and lets the wire become the fuse.

03
PROBLEM 03

The brand-name panels that fail when you need them most

Three-panel brands from the 1960s through the 1980s receive an automatic replacement recommendation. Many Federal Pacific breakers have been found to fail to trip when overloaded or during a short circuit. Zinsco breakers can fail to trip when needed, and the breaker can sometimes melt and fuse to the bus bar, making it difficult or impossible to disconnect, with corrosion and overheating as common companions. Challenger breakers have their own history of overheating and failing. If your home has one of these, you may already know: insurers increasingly force the issue at renewal or sale.

Start to Finish

How a Panel Job Works
at RSB, Start to Finish

A clear process. Real communication.
Quality work that stands behind it.

01

Step 1: A real person answers and triages

Sharee, or the on-call electrician, asks what is happening, when it started, and what changed. If it is a simple tripped breaker, we will try to walk you through it over the phone for free. Any heat, buzzing, or burning smell, and we treat it as an emergency and dispatch.

02

Step 2: We schedule and show up when we said

You get a window, we keep it, and you hear from us if anything shifts. "We will keep you updated" is not a slogan here; it is the operating manual.

03

Step 3: On-site diagnosis of the actual cause

We open the panel and look at what the symptoms have been pointing to: bus bar condition, breaker health, lug torque, signs of heat, the brand and era of the equipment, and how much capacity is genuinely left. You get a plain-language explanation of what we found, with photos.

04

Step 4: A written quote the next day, honored for 30 days

Estimates are free. Because copper and equipment prices move constantly, we price your job against real current material costs and get you a written quote, typically the next day. That number holds for 30 days, with no hidden fees.

05

Step 5: Permits and utility coordination, handled

For panel replacements and service upgrades, we pull the permit online, talk directly with the city, and schedule the SRP or APS disconnect and reconnect. You do essentially nothing except be home for work.

06

Step 6: The work, the inspection, and the walkthrough

Most panel replacements are done in a day. We label every circuit accurately, walk the city inspection through to a pass, clean up completely, and show you exactly what changed before we leave.

07

Step 7: One-year warranty, no paperwork games

Labor and materials are warranted for one year from completion. Your invoice is your warranty proof. There is nothing to register and nothing to lose.

Pricing, Honestly

What a panel job
costs, honestly

We do not publish panel prices, and we will not throw a blind number at you over the phone. Copper, breakers, and panel equipment are commodity-priced, and those prices move constantly. A number that was honest in March is a lie by August. What we promise instead is a free estimate, a written quote typically the next day, and a price that holds for 30 days.

For larger projects like full panel replacements and service upgrades, Affirm financing is available, with options ranging from 0% APR to standard installments, subject to credit approval.

Honest Pricing

We give you real numbers, not guesses.

Price Holds 30 Days

Your quote is locked in, not moving targets.

Amperage: repairing within your existing service versus upgrading to 200-amp capacity
Service entrance condition: whether the riser, mast, and meter-main need work along with the panel
Utility coordination: jobs requiring an SRP or APS disconnect are sequenced differently
Permit and inspection scope for your city

Valley Conditions

East Valley Conditions That Are
Hard on Electrical Panels

Panels in metro Phoenix live a harder life than panels almost anywhere else in the country.
Seven local realities shape the work we do.

Summer heat cooks outdoor panels

Valley panels overwhelmingly live outdoors or in garages that hit well over 110 degrees for weeks at a time. Heat accelerates everything that ages a panel: connections loosen as metal expands and contracts, breaker internals wear faster, and a marginal connection that would survive years in a mild climate becomes a hot spot by its second Phoenix summer.

The AC load nobody sized for

An air conditioner pulling hard ten hours a day is the single biggest load a Valley panel carries, and older panels were never sized for modern high-tonnage units plus everything else. Lights that dim when the AC kicks on are your panel telling you the margin is gone.

Monsoon season finds the weak link

Storm surges, brownouts, and the grid switching that follows outages all stress connections and breakers. Our promise every June is the same: get your panels checked before monsoon season.

A housing stock full of 1960s to 1980s panels

Mesa, Tempe, Chandler, and the older neighborhoods of Gilbert and Scottsdale grew rapidly in the very decades when Federal Pacific, Zinsco, and Challenger equipment was installed by the thousands, often paired with aluminum branch wiring.

Insurance companies are forcing the issue

We now regularly see insurers require panel replacement or an electrical inspection before writing or renewing a policy on older Valley homes. When that letter arrives, we inspect, document with photos, replace what is required, and give you the paper trail.

EV chargers are filling panels fast

The East Valley is adopting electric vehicles quickly, and a Level 2 charger is a large permanent load. The panels we open for charger installs are often already full. A proper load calculation, and sometimes a 200-amp upgrade, is what makes the charger safe rather than hopeful.

The Valley’s 55+ communities are running on original equipment

Communities like Sun Lakes, Leisure World, Sunland Village, and Dreamland Villa were built decades ago, and many homes still run their original panels. We work in these communities constantly and respect HOA processes.

Expertise Deep-Dive

Panel Expertise: What Four Decades at the Box Teaches You

The difference between a panel swap and a panel job done right lies in the details most customers never see.

01

Bus bars decide repair versus replace

The bus bars are the copper or aluminum spine that every breaker snaps onto. When we find fatigued, pitted, or heat-discolored main bus bars, repair stops being honest: new breakers on a failing spine just relocate the problem. Clean bars with a failed breaker or lug often mean a modest repair is right. This distinction is the heart of our repair-versus-replace framework.

02

Why Federal Pacific and Zinsco earn automatic replacement

A breaker has one safety job: to trip when the circuit is overloaded or shorted. Many Federal Pacific Stab-Lok breakers have been found to fail that test. Zinsco designs introduce a second failure mode: breakers that overheat, corrode, and sometimes melt onto the bus bar. These are not cosmetic upgrades — they are the removal of a known failure point.

03

Double-tapped and oversized breakers

A double-tap is two conductors landed under one breaker terminal rated for one. An oversized breaker is a 30-amp device protecting a wire rated at 20 amps. Both are shortcuts we constantly find, installed to make a symptom go away. Both defeat the protection the panel exists to provide, and both are on our must-fix list.

04

Load calculation before anything gets added

Before an EV charger, a spa circuit, or a casita subpanel, we run the load numbers: service size, existing demand, and what the addition really draws. Chargers installed without load calculations are among the dangerous conditions we repeatedly correct. The math takes minutes and prevents years of nuisance trips, or worse.

05

What a 200-amp service upgrade actually involves

A true service upgrade is more than a bigger box. The service entrance conductors, the riser or mast, the meter-main, the grounding electrode system, and the utility connection all have to be rated for the new capacity, coordinated with SRP or APS so your power is off for hours, not days.

06

Subpanels: capacity where you actually use it

Garages becoming workshops, casitas becoming rentals, and pool equipment pads all want their own subpanel: local breakers, shorter wire runs, and room to grow. A properly fed and bonded subpanel is often smarter than forcing every new circuit across the property.

07

Reading the warning signs in the right order

Whole-house flickering and random outages point to the service and panel. Single-room problems point to a circuit. Warmth, buzzing, or scorching at the panel face means stop and call now. Knowing which symptom belongs to which layer is why our calls end with a fixed cause instead of a stack of replaced parts.

FAQ

Electrical Panel Questions, Answered Straight

1.How do I know if my panel needs repair or full replacement?

The honest answer lives inside the box: bus bar condition, equipment brand and era, and how much capacity your household actually needs. Fatigued main bus bars or a dangerous brand mean replacement. A failed breaker or lug on healthy bars often means a repair. We tell you which, with photos, and quote it in writing.

2.Do you replace Federal Pacific, Zinsco, and Challenger panels?

Yes, regularly, across the whole Valley. These brands have documented histories of failure, and we replace them with modern equipment from manufacturers such as Square D, Eaton, Siemens, and GE. We also document the replacement for your insurance company.

3.Will my insurance company really make me replace my panel?

We see it regularly: carriers requiring panel replacement, aluminum wiring remediation, or an inspection before they will write or renew a policy on an older Valley home. We provide the inspection, the photos, the fix, and the paper trail.

4.How long does a panel replacement take, and will I lose power?

A residential panel replacement is a one-day job in the standard case. Power is off during the work itself, and when SRP or APS must disconnect service, we schedule utility windows to keep the outage as short as possible.

5.Do I need a permit for a panel upgrade in Mesa or the East Valley?

Yes, panel replacements and service upgrades are permitted and inspected in every Valley city, and that is a good thing. We pull the permit online, coordinate with city staff, and walk the inspection through to a pass. You do nothing.

6.My lights flicker all over the house. Is that the panel?

Whole-house flickering and random outages are the two panel warning signs we tell homeowners never to ignore. It can also be a utility-side or service-entrance problem, which is why we diagnose before we quote. Either way, do not wait on that one.

7.My breaker keeps tripping. Can I just put in a bigger breaker?

Please do not, and do not let anyone else do it either. A breaker that trips is protecting a wire rated for exactly that breaker size. Oversizing it removes the protection and turns the wiring into the weak point. Find the cause; that is what we are for.

8.Can my panel handle an EV charger or a hot tub?

Maybe, and the load calculation answers it in minutes. Many older panels are already full, packed with tandem breakers. Sometimes a subpanel solves it, sometimes a 200-amp upgrade is the honest path. We will tell you which before you buy anything.

9.How much does a panel upgrade cost?

We do not publish prices because equipment and copper costs change constantly, and a stale number would mislead you. Estimates are free, the written quote typically comes the next day, and it is honored for 30 days. Affirm financing is available for larger jobs, subject to credit approval.

10.What is your warranty on panel work?

One year on labor and materials from completion. If you supply your own materials, the warranty covers only our labor. Your invoice is your warranty proof.
