Electrical Repairs (Commercial)

When the power falters in a Maine business, the clock starts immediately — a tripped circuit in a commercial kitchen, a dark sales floor, or rooftop equipment that won’t start can stop revenue cold and send customers elsewhere. MC Electric Comfort Systems provides commercial electrical service and repair for offices, retail stores, restaurants, and professional and medical spaces across Central Maine, the Kennebec Valley, and the Midcoast. As a veteran-founded, dual-trade contractor licensed in Maine, New Hampshire, and Massachusetts, we troubleshoot fast, fix it to code, and keep your space safe, operational, and inspection-ready — with free estimates and upfront pricing.

Commercial Electrical Is a Different Animal

A commercial building is not just a bigger house. The loads are heavier, the code requirements for an occupied place of business are stricter, and a failure is measured in lost sales, spoiled inventory, and customers who don’t come back. Many commercial buildings run on three-phase power rather than the single-phase service a home uses — the standard for motors, larger HVAC equipment, commercial refrigeration, and machinery — and troubleshooting it takes an electrician who works on it regularly. The distribution is more involved too: a main service feeding subpanels, distribution panels, and dedicated circuits across a floor plan built for staff and the public. We work in that environment every day and approach it the way our veteran roots taught us — plan the work, then work the plan — so the diagnosis is right the first time and the fix holds up under real commercial demand.

Commercial Electrical Repairs We Handle

Most service calls come in because something stopped working, something keeps tripping, or something an inspector or insurer flagged needs to be corrected. These are the commercial problems we’re called out for most:

• Breakers and circuits that keep tripping: In a business, a nuisance trip rarely is one — it usually means an overloaded circuit, a failing breaker, a fault in connected equipment, or a distribution problem. We trace it to the real cause instead of resetting it and waiting for it to happen again mid-shift.
• Three-phase and equipment power issues: Motors that won’t start, equipment running hot, or a lost phase can damage expensive machinery and refrigeration. We diagnose three-phase faults, voltage and connection problems, and the disconnects and circuits that feed your equipment.
• Dedicated circuits for commercial equipment: Kitchen appliances, point-of-sale and IT, medical and dental equipment, and dedicated HVAC loads each need a properly sized, code-compliant circuit. We add, repair, and correct these so sensitive equipment runs reliably.
• Commercial lighting and circuits: Flickering, failing ballasts and drivers, dark sections of a sales floor or parking area, and overloaded lighting circuits. We repair these and tie into broader commercial lighting work when it makes sense.
• Panels and distribution: Overloaded or aging commercial panels, no room for new circuits, warm or buzzing equipment, scorching, or distribution that was never sized for how the space is used today.
• Outlets, wiring, and safety devices: Dead or warm receptacles, failing GFCI protection in kitchens and restrooms, loose connections, and wiring damaged by water, age, or a previous patch job.

Code Compliance, Safety, and Minimal Downtime

When the public and your employees are in the building, the electrical system carries a higher bar — and so does the liability. Commercial occupancy brings requirements a home never faces, and a failed inspection or an insurance flag can hold up a lease, a renovation, a certificate of occupancy, or a renewal. We do every repair to the National Electrical Code as adopted in Maine, correct the deficiencies an inspector or insurer points to, and leave the work properly grounded, bonded, and labeled. When a job requires a permit and inspection, we handle that process so the work is documented and signed off.

We also know the real cost of an electrical problem usually isn’t the repair — it’s the hours you’re closed or the equipment sitting idle while you wait. So we troubleshoot to isolate the fault quickly and keep as much of your operation running as possible, tracing the affected circuits and distribution with proper test equipment instead of guessing. Where it makes sense, we schedule the disruptive part of a repair around your hours — before you open, after you close, or on a slower day — so the lights stay on while customers are in the building.

Emergency and After-Hours Electrical Response

Some commercial electrical problems can’t wait for business hours — a partial power loss in a restaurant, a tripped circuit threatening a walk-in cooler full of product, a burning smell at a panel, or storm damage that leaves part of your space dark or unsafe. When a fault is a genuine safety hazard or it’s stopping you from operating, call us and we’ll respond. We stabilize the immediate hazard first, get you safely back online where possible, and plan any larger corrective work around your schedule. Because we’re one company handling both your electrical and your comfort systems, you have a single number to call when something critical fails.

We also won’t patch the same problem twice to avoid an honest conversation. Repeated trips across multiple circuits, a distribution panel that’s full, service that was never sized for the equipment you run now, or a buildout that’s outgrown its original electrical all point past a single repair — and the right answer is often added capacity or an electrical panel and distribution upgrade. We’ll show you what we found, lay out the options in plain language, and let you decide on the timing and budget that work for your business.

The Dual-Trade Advantage: One Contractor for Power and Comfort

This is where MC Electric Comfort Systems is genuinely different for a business. A large share of commercial electrical calls live right at the line between electrical and HVAC — a rooftop unit that trips its breaker, a circuit that can’t carry a new piece of equipment, a corroded disconnect, or refrigeration and comfort systems that won’t start on a power fault. To an electrician who doesn’t know HVAC that’s a guessing game; to a mechanical contractor who doesn’t do electrical the wiring is off-limits. We do both, in-house. And it goes beyond emergencies: a business can use one licensed contractor for both its electrical service and its commercial HVAC and cooling — instead of two companies, two schedules, two invoices, and finger-pointing when nobody owns the gray area. One team, one call, one point of accountability matters a great deal when you’re trying to keep a business open.

Keeping Your Maine Business Operational

Commercial electrical work is no place to cut corners — the difference between a repair that looks finished and one that’s actually safe and code-compliant is often invisible until it fails, and in a business that failure has an audience. Every repair we make is performed by licensed electricians and brought up to current code, backed by free estimates and upfront pricing. We serve businesses throughout Central Maine and the Midcoast, including Augusta, from our home base in West Gardiner. Contact us today to schedule commercial electrical service, and we’ll tell you straight what’s going on and how we’ll keep you running.

Commercial Electrical Questions Maine Business Owners Ask Us

Do you work on three-phase power and commercial panels?

Yes. We regularly troubleshoot and repair three-phase power, commercial panels, subpanels, and distribution systems, along with the dedicated equipment circuits that feed motors, refrigeration, HVAC, and machinery. We diagnose them with proper test equipment and bring every repair up to current code.

Can you do the repair after hours so we don’t lose business?

Wherever it’s practical, yes. We schedule the disruptive part of a repair around your hours — before you open, after you close, or on a slower day — so you stay open while customers are in the building. We’ll talk through the timing with you up front and plan the work to minimize your downtime.

Do you respond to commercial electrical emergencies?

Yes. When a fault is a genuine safety hazard or it’s stopping you from operating — a partial power loss, a threatened walk-in cooler, a burning smell at a panel, or storm damage — call us and we’ll respond. We stabilize the immediate hazard first, get you safely back online where possible, and plan any larger corrective work around your schedule.

Will the work pass inspection and keep us code-compliant?

That’s the point of doing it right. We perform every repair to the National Electrical Code as adopted in Maine, correct the deficiencies an inspector or insurer flags, and leave the system properly grounded, bonded, and labeled. When a job requires a permit and inspection, we handle that process so the work is documented and signed off.

Can one company handle both our electrical and our HVAC?

Yes — that’s our core advantage. We’re a dual-trade contractor that handles both licensed electrical work and HVAC in-house, so a business can use one team for its power and its comfort systems. That means a single point of accountability, especially for the many problems that sit right where the electrical and the commercial HVAC meet, instead of two companies pointing at each other.

Do you offer free estimates on commercial electrical work?

Yes. We provide free estimates and upfront pricing on commercial electrical service and repairs, so you’ll know the scope and cost before any work begins. We’re licensed in Maine, New Hampshire, and Massachusetts and serve businesses across Central Maine, the Kennebec Valley, and the Midcoast.

Diagnosis, code requirements, and recommendations depend on your building’s specific conditions and occupancy and are confirmed during an on-site evaluation. We provide a firm price before any repair begins.
