For traditional plan-spec projects, an architect will hire an engineer to produce drawings for a project’s mechanical, electrical and plumbing work. Subcontractors in each of those areas will then bid the project, and those that are awarded the work will utilize those drawings.

In design/build projects, the subcontractors themselves either have in-house engineering capabilities, or they often are aligned with an outside strategic engineering partner. Collectively, they work with the architect and owner to develop the design and drawings in accordance with that owner’s vision.

We offer complete design-build capabilities with in-house engineers and project managers.  The single-source capability of a design-build structure lends to reduced job costs and fast-track the development of a project.

Our technicians have over 100 years combined experience in the trenches of commercial and industrial electricity.




Tell me about your electricians.


All of our technicians are undergo an intense union training process. 8,000 hours of coursework and on-the-job experience before achieving journeyman status to construct safe, effective, and powerful electrical systems. Most of our electricians have been journeyman for over 15 years, with significant experience in commercial environments and industrial power needs. All are OSHA 30 - certified.




Does O'Carroll Electric charge for estimates?


No. Estimates are provided at no cost.




What supplies and equipment do you use for a job?


We'll determine what we need based on project scope. We have close partnerships electrical suppliers and construction vendors in area, including Steiner, Amperage, Sunrise Electric, Welch Bros., Connexion, Lift Works. We have in-house scissor lifts, backhoes, skid steers, trailers, and thousands of electrical supplies SKUs.




Are you licensed, bonded, and insured?


Yes. Be sure any contractor you hire is licensed, bonded, and insured.





How do commercial electricians differ from residential?


Commercial-industrial work is more powerful and diverse. A residential system typically includes a 120/208 single-phase service - this includes light transformer, breakerbox, and circuits. Commercial systems invo Controllers, contactors, relays, transformers, raceways, and sensors and many other factors that require a well-trained, experienced electrical technician.




What can you tell me about lighting?


In a commercial environment, it's critical to have LED lighting throughout your facility. Within the past decades, it has become a no-brainer to have LEDs. Over the long run, you'll enjoy significant savings.




How long will it take for the work to be done?


Electrical contractors who are well versed with what they do will tell you the average time period it would take them to complete the task at hand. Some electrical assignments can be hard to estimate how long they will take to complete because of issues that arise along the way. If you will be paying the contractor on an hourly rate, it’s good to know how long it will take.




What are your most common services?


Service upgrades, lighting retrofits, power excavation. Our most common project is a service upgrade - often the replacement of old, potentially unsafe switchgear or perhaps. These require the help of a licensed electrician - anything over 200A can be very dangerous




What's the difference between a union and non-union electrician?


Union electricians must undergo rigorous training and a 4-year apprenticeship program. They are trained in the latest safety and technology practices.




Should I upgrade my business' lighting?


If your business is. Not only will your monthly energy consumption decrease, but you'll have significantly lower long-term maintenance costs - and you'll get a lucrative check from ComEd under their Energy Efficiency program. LEDs are a rock-solid business investment.
