Garwin Electric Electrical Services for Olathe Homes and Businesses

How do I know if my home needs a panel upgrade?

A few signs point clearly in that direction: breakers that trip often, a panel rated at 100 amps or less, lights that dim when large appliances kick on, or a home that has added significant load over the years without a panel change. Many homes in and around Olathe were built with panels sized for a different era. If you are adding an EV charger, a home office, or any high-draw equipment, we recommend a load calculation before you proceed. Call us and we will walk you through what the panel can handle and what an upgrade would involve.

What causes a breaker to trip repeatedly?

Repeated tripping usually means one of three things: the circuit is carrying more load than it was designed for, a device or appliance on the circuit is drawing too much current, or the breaker itself is worn and no longer holding reliably. In some cases, a wiring fault is the cause. We diagnose the source rather than just resetting the breaker and leaving. If the panel or a specific circuit is the problem, we will tell you honestly what the fix looks like.

Is the electrical work permitted and inspected?

For jobs that require a permit under local code, we pull the permit and the work is inspected. Permit requirements vary by job type and jurisdiction. When you call for a quote, we will let you know upfront whether the job you are describing requires a permit and what that process looks like. Work performed by licensed electricians follows current code, and we do not cut corners to avoid the inspection step.

Is older wiring in a home actually dangerous?

It can be. Knob-and-tube wiring was not designed for today's electrical loads, and it lacks the grounding that modern code requires. Aluminum branch-circuit wiring from the 1960s and 1970s has a higher risk of loose connections and overheating at outlets and switches. Two-wire systems with no ground create shock and fire risks that ungrounded outlets do not protect against. If your home has any of these systems, an electrical safety inspection is a practical first step so you know exactly what you are dealing with.

What do I need to install a Level 2 EV charger at home?

A Level 2 charger requires a dedicated 240-volt circuit sized for the charger's amperage, typically 40 to 50 amps for most home installations. We evaluate your panel capacity before the job starts to confirm there is room for the new circuit. If the panel is already near capacity, we handle the panel work at the same time. We install Level 2 chargers for all vehicle makes, including Tesla wall connectors, and we can usually schedule the job quickly.

How does backup generator wiring work?

A standby generator connects to your home's electrical system through a transfer switch, which safely isolates your home from the utility grid when the generator is running. We handle the generator hookup, the transfer switch installation, and the wiring from the generator to your panel. We size the transfer switch to the circuits you want protected and test the system before we leave. For homes in Johnson County, where severe storms and tornadoes can knock out power for extended periods, a properly wired standby generator is a practical investment.

Do I need to be home while the work is being done?

For most jobs, yes. We need access to the panel, the work areas, and often the attic or crawl space depending on the scope. For a quick outlet repair or a single fixture swap, the job may not take long, but someone should be available to let us in and confirm the work when we are done. If your schedule is tight, call us and we will work out an arrival window that fits.

How does pricing work? Will I get a quote before work starts?

When you call, describe what you are seeing and we will give you honest information about what the job is likely to involve. Electrical work varies in cost depending on scope, materials, and what the job turns up once we open the wall or panel. We do not give vague ranges and then revise them at the door. Our goal is to give you a clear picture before any work begins so there are no surprises when the job is done.

Why would an outlet or switch stop working?

The most common causes are a tripped GFCI outlet upstream on the same circuit, a loose wire connection at the outlet or switch, a tripped breaker, or a worn device that has simply failed. A sparking switch or one that feels warm to the touch is a more urgent concern and should not wait. We repair and replace outlets and switches, trace the circuit when the cause is not obvious, and leave everything code-compliant.

What does it mean when lights flicker or dim?

Occasional dimming when a large appliance starts up is common and usually points to a circuit or panel capacity issue rather than a wiring fault. Persistent flickering, flickering in multiple rooms, or lights that dim and brighten on their own can indicate a loose connection, a failing breaker, or a larger wiring problem. It is worth having us take a look rather than waiting to see if it gets worse.

Is surge protection worth it for a home in this area?

For homes in Johnson County, we think it is one of the more practical electrical upgrades available. Lightning is a real and frequent threat in this part of Kansas, and a single nearby strike can damage or destroy electronics, appliances, and other equipment throughout a home. A whole-home surge protector installs at the main panel and catches voltage spikes before they reach your devices. It is a job we can typically complete in a single visit.
