What are the signs a breaker needs replacing instead of resetting?

Watch for: A breaker that won't reset Breaker feels warm to the touch Breaker trips the instant you plug something Scorch marks around the breaker Burning smell near the panel Breaker hums In Johnston, we see this most in homes with the original panels, where breakers have handled 20-plus years of Iowa summers and winters. If it stops working within a day or two after resetting, call us before it fails for good.

Why does my breaker keep tripping when I run the air conditioner?

In most cases, the air conditioner itself isn't the problem—the real culprit is a breaker that can't handle the higher electrical demand, which frequently happens after installing a newer, more powerful AC unit. Central air systems draw continuous heavy power while running, causing older or undersized breakers to shut down automatically as a built-in safety measure. Instead of blindly replacing parts and hoping for the best, we measure your actual amperage draw against the breaker's rated capacity. As long as your existing wiring is in good shape, putting in a correctly matched replacement typically resolves the tripping issue in a single service call.

What if my panel has Zinsco or Federal Pacific breakers?

Zinsco and Federal Pacific panels have a documented history of breakers that fail to trip during an overload, the exact opposite of what a breaker should do. If your Johnston home still has one of these panels, we'll walk you through your options instead of a like-for-like swap that would just repeat the problem. Sometimes a compatible replacement breaker still makes sense. Other times, the safer move is a full panel upgrade.

What other services does Mr. Electric offer in Johnston?

Beyond breaker replacement, we handle the full range of panel work Johnston homeowners need. That includes electrical panel upgrades for houses that have outgrown their original service size and electrical panel repairs for damage that does not warrant a full panel swap. We also install EV charger circuits for homeowners adding a Level 2 charger in the garage, as well as surge protection to guard the rest of your electronics against Iowa's storm-season power surges. If it runs through your panel, we can likely help.

Is a circuit breaker replacement enough to bring an older Johnston home up to code?

Not always, and we'll say so upfront. A breaker replacement brings that circuit into compliance with National Electrical Code requirements for its rating and for GFCI or AFCI protection, where required. It doesn't rewire your whole house or update a panel that's undersized for your current load. We check the full panel during the visit and flag anything else that's out of code so you can decide whether to handle it now or later, no pressure either way.

How We Replace a Faulty Breaker

Every circuit breaker replacement starts with a load analysis, not a guess. We check breaker sizing against your panel's rated capacity, look for thermal stress on the bus bars, and test for ground faults that a simple reset won't fix. Homes in Johnston built in the 1990s and early 2000s often have breakers rated for a smaller electrical load than a modern kitchen or home office demands. If your panel itself is aging out, our Des Moines electrician team can also handle a full panel upgrade rather than a one-off swap.

Once we've confirmed the fix, the replacement itself moves fast. We match the new breaker to your panel's brand and amperage, torque every panel connection to spec, and confirm GFCI protection where the National Electrical Code requires it, like kitchens, bathrooms, and outdoor circuits. No shortcuts. For panels with a history of failure, Zinsco and Federal Pacific models among them, we'll walk you through whether a targeted breaker swap makes sense or if it's time to talk panel replacement. Thermal imaging lets us spot a breaker running hot before it becomes a bigger problem.

Iowa's summers push central air hard, and Johnston's electrical infrastructure feels it every July when window units and central systems run at once. We size every new breaker for that real-world load, not just the label stamped on the old one. Get it wrong, and you're back to square one with the same nuisance trip.

What Homeowners Get With Every Circuit Breaker Installation Our Johnston Electricians Perform

Six licensed electricians serve the Des Moines metro from Mr. Electric of Central Iowa, most of them with 15 years of hands-on experience in Iowa homes. That's not a marketing line; it's who shows up at your door in Johnston, Urbandale, or Grimes when a breaker won't reset. Voted Des Moines' best electrician in 2024 and 2025, we bring that same standard to every panel we touch, whether it's a starter home or a two-story built in the last few years.

A breaker that won't reset after two tries is a safety issue, not a nuisance you live with. We've been doing this since 2001, long enough to have replaced breakers in nearly every panel brand installed across Ankeny, Polk City, and the rest of central Iowa. A failing breaker rarely travels alone. We'll check your surge protection and run a quick safety inspection while we're already inside the panel, since catching a second issue now beats a second service call later. Ready to fix the breaker that keeps tripping? Schedule an appointment, and we'll get a licensed electrician out to your Johnston home.
