Your electrical wiring works behind the walls, ceilings, outlets, switches, panels, and connected equipment throughout your property. Although it is rarely visible, wiring plays an essential role in delivering dependable power to lighting, appliances, machinery, technology, and other electrical systems.
Outdated, damaged, improperly installed, or insufficient wiring can lead to flickering lights, repeated breaker trips, unreliable outlets, overheating components, and other electrical concerns. As properties age and electrical demand increases, the original wiring may no longer provide the capacity or performance needed for modern use.
Hertzler Electrical Services provides professional electrical wiring upgrades for homes, businesses, industrial facilities, agricultural properties, and active job sites throughout Duncan, Marlow, and nearby Southwest Oklahoma communities. Our electricians evaluate existing wiring, identify areas that may need improvement, and recommend practical solutions based on the property’s condition and electrical requirements.
Whether you are renovating, adding equipment, replacing aging materials, or addressing recurring power problems, our team can help improve the safety, capacity, and reliability of your electrical system.

What it involves
Electrical wiring upgrades involve replacing, repairing, expanding, or modifying wiring to better support a property’s electrical needs. The work may include updating old conductors, adding circuits, replacing damaged connections, improving grounding, or installing wiring for new fixtures and equipment.
Every wiring project is different. Some properties may need a limited repair in one area, while others may benefit from broader improvements throughout the building. The appropriate solution depends on the age of the wiring, its current condition, the type of electrical equipment being used, and any future improvements planned for the property.
Our electricians begin by evaluating the existing system and identifying visible signs of deterioration, damage, improper modifications, or insufficient capacity. We then explain the available options and develop a plan designed around the property’s needs.
Scope of work
Hertzler Electrical Services can complete wiring improvements for residential, commercial, industrial, agricultural, and construction environments. The exact scope of work depends on the condition of the system and the project goals.
01
Older properties may contain wiring materials or installation methods that no longer support modern electrical use. Aging insulation, deteriorated connections, and limited circuit capacity can affect system performance.
02
Wiring may become damaged due to heat, moisture, pests, construction activity, overloaded circuits, loose connections, or physical impact. Damaged insulation and exposed conductors can create serious electrical concerns.
03
Additional circuits may be needed when a property adds appliances, equipment, lighting, outlets, machinery, or other high demand electrical components. Relying on existing circuits that are already heavily loaded can contribute to repeated breaker trips and inconsistent performance.
04
Large appliances, generators, heating and cooling equipment, machinery, commercial devices, and specialized systems may require dedicated circuits. A dedicated circuit helps provide consistent power without sharing the electrical load with unrelated devices.
05
New layouts, renovations, workstations, equipment areas, and room improvements may require additional outlets or switches. We install wiring for new components and can replace connections that are loose, damaged, outdated, or improperly installed.
06
Adding recessed lighting, security fixtures, outdoor lighting, commercial fixtures, or updated controls may require new or modified wiring. We provide the electrical support needed for dependable lighting operation.
07
Grounding and bonding help support electrical safety by providing appropriate paths for electrical current under certain fault conditions. Older or modified electrical systems may need improvements to these protective components.
08
Renovations often change how electricity is used throughout a property. Kitchens, bathrooms, offices, additions, workshops, and expanded commercial areas may require new circuits, outlets, switches, lighting, and equipment connections.
09
Commercial and industrial properties may need wiring for machinery, production equipment, tools, controls, lighting systems, and other specialized electrical components.
Warning signs
Electrical wiring problems are not always easy to see, but they may create noticeable warning signs throughout the property. These issues should not be ignored, especially when they happen repeatedly. Property owners can review the Electrical Safety Foundation International’s home wiring safety tips to learn about common warning signs that may indicate aging, damaged, or overloaded wiring. Recurring electrical problems should be evaluated by a qualified electrician before they cause more serious disruptions.
You may need electrical wiring upgrades when:
These symptoms can have several possible causes. A professional evaluation can help determine whether the wiring, panel, circuit, fixture, equipment, or connection is responsible.
Benefits
Damaged wiring, loose connections, and deteriorated insulation may increase the possibility of overheating, arcing, and electrical failure. Updating affected wiring helps remove known concerns and improves the overall condition of the system.
Older properties were often built before modern appliances, electronics, chargers, lighting systems, and equipment became common. Electrical wiring upgrades can help the system support current electrical use more effectively.
Flickering lights, unreliable outlets, and repeated circuit interruptions may be connected to wiring or load problems. Correcting these issues can provide more stable and dependable electrical performance.
Generators, machinery, appliances, lighting, heating and cooling equipment, and other electrical additions may require new wiring or dedicated circuits. Planning the wiring before installation helps ensure the equipment receives appropriate electrical support.
Updated wiring allows property owners to place outlets, switches, lighting, and equipment connections where they are actually needed. This can make remodeled spaces more practical and convenient.
Electrical problems can affect appliances, electronics, tools, machinery, and other valuable equipment. Reliable wiring and properly installed circuits help provide consistent power to connected devices.
Related services
Wiring improvements are often completed alongside other electrical installations and upgrades. Hertzler Electrical Services provides related services that help create a more capable and reliable electrical system.
A generator installation requires appropriate wiring, transfer equipment, panel connections, and electrical capacity. We install generator systems designed around the property’s backup power needs and existing electrical setup.
New wiring and circuits must connect to a panel capable of distributing the additional electrical load. If an existing panel is outdated, damaged, or lacking capacity, an electrical panel upgrade may be recommended.
New wiring may support outlets, switches, breakers, controls, timers, sensors, junction boxes, disconnects, and other electrical components. We install compatible components based on the property and equipment requirements.
Lighting projects may require new wiring, switches, controls, or dedicated circuits. We provide lighting installation services for residential, commercial, industrial, outdoor, security, and specialty lighting systems.
Electrical surges can damage appliances, electronics, controls, lighting, and connected equipment. Surge protection installation can provide an additional layer of protection for the property’s electrical system.
Electrical wiring should not be repaired or modified without proper knowledge of circuits, loads, connections, grounding, and electrical system requirements. Incorrect wiring work can create hidden problems that may not become noticeable until the system is under increased demand.
