A commercial electrical contractor designs, installs, upgrades, and maintains the electrical systems that keep a business running, from the service panel and wiring to lighting, generators, and low voltage cabling. For a Duncansville business, that means one licensed team can wire a new build, retrofit aging lighting, upgrade a strained panel, and keep you code compliant, instead of you juggling three separate trades.
Adams Electric has done this work across Blair County since 1919. We are a family owned company, now in our fourth generation, serving Duncansville, Hollidaysburg, and Altoona with commercial, industrial, and residential electrical service. This guide explains what a commercial contractor actually handles, what current federal data says about the stakes, and how to choose the right one for your building.
Key Takeaways
- A commercial electrical contractor covers installation, upgrades, repairs, and ongoing maintenance for offices, stores, restaurants, warehouses, and industrial sites.
- Commercial buildings are heavy power users. The commercial sector bought 36.8% of all US electricity in 2025, so efficiency and reliability show up directly on your bottom line.
- Lighting retrofits, electrical panel upgrades, and backup generators are the three projects with the fastest payback for most local businesses.
- Electrical malfunctions still cause thousands of nonresidential building fires every year, which is why licensed, code compliant work is not optional.
- Hire a licensed and insured contractor with real commercial experience, local references, and a clear written estimate.
What does a commercial electrical contractor do?
Commercial buildings run on electricity. The commercial sector bought 1.49 trillion kWh in 2025, about 36.8% of all US electricity retail sales, according to the U.S. Energy Information Administration. That scale is why business electrical work is its own discipline, separate from wiring a house.
A commercial electrical contractor handles four broad areas: new installation, repairs, exterior systems, and preventive maintenance. Our commercial and industrial services at Adams Electric cover equipment wiring, power distribution networks, audio and visual installs, cabling for phone, internet, TV, and data, electric heating, and commercial generator installation. On the repair side, we diagnose electrical faults, correct code violations, and maintain machinery, wiring, and equipment so a small problem does not become a shutdown.
Exterior work matters too. We install and repair parking lot lighting, security cameras and lighting, occupancy sensors, and exterior signage lighting. One contractor. Every system. That single point of accountability is the practical reason businesses hire a commercial electrician instead of a general handyman.
Commercial lighting and LED retrofits that lower your bills
Lighting is one of the largest controllable costs in a commercial building. It accounts for about 10% of total energy use in US commercial buildings, and electricity makes up 60% of that energy, based on the latest federal figures from the EIA. Cut your lighting load and you cut a real line item every month.
The clearest win is switching to LED. The U.S. Department of Energy estimated that LED adoption saved 1.3 quadrillion Btu and $14.7 billion for consumers in a single year (DOE). LEDs also last far longer, which cuts the ladder time and maintenance calls that eat into a facility budget.
For a Duncansville storefront, office, or warehouse, a retrofit usually pairs new fixtures with smarter controls. We design office, store, and restaurant lighting, upgrade parking lot lighting, and add occupancy sensors so unused areas are not burning power at 2 a.m. The result is lower bills, better light quality for staff and customers, and fewer service interruptions.
Panel and switchboard upgrades that keep your building safe
Old and overloaded electrical systems are a genuine fire risk. In 2023 there were an estimated 7,400 nonresidential building fires caused by electrical malfunction in the US, with $354.4 million in property loss, according to the U.S. Fire Administration. The one bright spot: those fires fell 7% over the previous decade, largely because of better equipment and stricter code enforcement.
Your electrical panel or switchboard is the heart of that safety story. Signs it is time for an upgrade include breakers that trip often, added equipment the panel was never sized for, flickering lights, warm panel covers, or plans to expand. Older buildings around Blair County sometimes still run on panels that predate the loads they now carry.
A commercial upgrade is more than swapping a box. We size the service to your real and future demand, correct code violations, and re-terminate equipment wiring so everything is safe and inspection ready. You can see the kind of work we do on our projects page. Done right, a panel or switchboard upgrade removes a hazard and gives you room to grow.
Backup generators for Duncansville power outages
Power reliability has gotten worse, not better. US electricity customers averaged 11 hours of interruptions in 2024, nearly double the average of the prior decade, the EIA reported, driven mostly by major storms. Central Pennsylvania sees its share of winter storms and summer wind events, and every hour offline has a cost.
Those costs add up fast across the country. A national lab analysis found that major US power outages cost customers about $67 billion a year on average, and $121 billion in 2024 alone (Oak Ridge National Laboratory). For a business, downtime means spoiled inventory, idle staff, lost sales, and unhappy customers.

A properly sized standby generator and automatic transfer switch keep you running when the grid does not. We handle commercial and industrial generator installation, from sizing the unit to your critical loads to wiring the transfer equipment. Restaurants protecting refrigeration, medical offices, warehouses, and manufacturers with sensitive machinery see the fastest return on backup power.
How to choose a commercial electrical contractor in Duncansville, PA
The stakes are high enough that the contractor you pick matters. With major US outages costing tens of billions a year and electrical faults still starting thousands of fires, the difference between a licensed commercial electrician and a low bid is measured in safety, uptime, and rework. Hiring well protects your building and your budget.
Use this checklist when you compare contractors:
- Licensed and insured. Confirm current licensing and liability insurance before any work starts. Ask for proof, not a promise.
- Real commercial and industrial experience. Wiring a plant, a switchboard, or a build-out is not the same as residential work. Ask about jobs like yours.
- Local presence and references. A contractor rooted in Blair County can respond faster and stands behind its reputation. Adams Electric has treated clients like family since 1919, and you can read our story on our about us page.
- Clear written estimates. You want honest, itemized quotes so there are no surprises. Vague pricing is a warning sign.
- Code and permit handling. Your contractor should pull permits, meet current code, and leave the job inspection ready.
- Responsiveness. Electrical problems do not wait for business hours. Ask how emergencies are handled.
When you are ready, contact Adams Electric for an estimate on your commercial or industrial project.
Frequently Asked Questions
How much does commercial electrical work cost in Duncansville, PA?
It depends on the scope. A lighting retrofit, a panel upgrade, a generator install, and a full build-out are very different jobs. The honest answer is that a good contractor visits your site, reviews your loads and goals, and gives you an itemized written estimate. Beware of a firm quote given sight unseen.
Do I need a licensed electrician for commercial work?
Yes. Commercial and industrial electrical work must meet code, pass inspection, and be covered by proper insurance and permits. A licensed contractor protects you from liability, failed inspections, and unsafe installations that can void coverage or cause fires.
What areas does Adams Electric serve?

How do I know if my building needs a panel or switchboard upgrade?
Common signs include breakers that trip repeatedly, warm or discolored panel covers, flickering lights, added equipment the panel was not sized for, and any plan to expand your operation. If you see these, have a commercial electrician evaluate your service.
Can you install a backup generator for my business?
Yes. We handle commercial and industrial generator installation, including sizing the unit to your critical loads and wiring an automatic transfer switch so power restores itself when the grid goes down. You can find more answers on our FAQ page.
