Commercial Services We Provide

New Construction & Tenant Buildouts

Whether you're opening a new retail location, expanding office space, or converting a shell into a fully functional restaurant, we handle the complete electrical infrastructure. This includes branch circuit installation, lighting design and layout, HVAC controls, data/communication rough-in, fire alarm design, and integration with building management systems.

We work closely with general contractors, architects, and other trades to coordinate timing and sequencing. We understand the critical path on a construction project and can work during off-hours to minimize disruption to existing tenants. Our team prepares and submits all permit applications, coordinates with Eversource for service upgrades, and ensures every inspection passes on the first attempt.

Three-Phase Power Systems

Commercial and industrial operations require three-phase power for heavy loads — whether it's HVAC compressors, production machinery, welding equipment, or large air handlers. We design, install, and troubleshoot complete 3-phase systems from the utility meter all the way through to individual equipment connections.

Our experience includes motor control centers (MCCs), variable frequency drives (VFDs), soft starters, power factor correction, load analysis, and phase balancing. If a piece of equipment won't power up or is running inefficiently, we diagnose the problem and get it back online. We also handle the load calculations and engineering documentation required for larger projects.

Commercial Electrical Panels & Service Upgrades

A commercial panel upgrade is one of the most common projects we do. Whether you're expanding capacity (adding circuits for new equipment), modernizing an outdated panel, or installing a new 200A, 400A, or 600A service, we've done hundreds of these in Connecticut. Many panel upgrades need to happen with minimal downtime — we coordinate carefully to transfer the load, test the new service, and bring systems online without leaving you dark.

We handle residential and commercial multi-family properties too. Common scenarios: adding capacity for EV chargers, upgrading sub-panels, installing new circuits for renovated units, and code compliance work. All work is performed to the latest National Electrical Code (NEC) standards and Connecticut amendments.

LED Lighting Design & Energy Audits

LED retrofits can reduce your lighting energy costs by 50–70%, and we install them in retail stores, warehouses, offices, parking lots, and industrial facilities. Beyond just swapping bulbs, we design efficient layouts, choose appropriate color temperatures for the space (warm for retail/restaurants, cool for offices and manufacturing), and integrate controls like motion sensors, dimmers, and daylight harvesting systems.

We can conduct a free lighting audit to identify savings opportunities and recommend fixtures and layouts that work for your operation. For large retrofits, we coordinate in phases to keep your facility operational. We also handle all emergency lighting and exit lighting required by code.

Fire Alarm Systems & Life Safety

Most commercial buildings require fire alarm systems. We design, install, program, and maintain systems that protect occupants and property. This includes pull stations, smoke and heat detectors, notification appliances (horns, strobes), control panels, monitoring system integration, and backup batteries. We're familiar with systems from major manufacturers and can install new systems or integrate with existing infrastructure.

Fire alarm work requires precise code knowledge and coordination with local fire departments. We handle all permitting, inspection coordination, and documentation. We can also provide ongoing monitoring and maintenance contracts.

Data & Structured Cabling

Modern offices and facilities depend on reliable data infrastructure. We install Cat6 and Cat6A cabling for high-speed networks, design and terminate wall plates and patch panels, run cable runs through walls and above ceilings, and integrate voice, video, and data systems. We can handle both new installations and upgrades to existing networks.

For server rooms, we design power distribution, cooling, and cable management. For offices, we route cabling cleanly through walls so it's invisible to tenants and clients. All work is tested and documented to industry standards.

Emergency Electrical Service (24/7)

When your commercial operation has an electrical failure, you lose revenue every minute you're down. We offer same-day emergency service — call us at 203-389-5112 and we'll get a technician to you quickly. Common emergency calls include breakers that won't reset, equipment that won't power up, complete circuit outages, damage from storms or accidents, and ground faults that trigger safety shutdowns.

Our team is trained to diagnose problems fast and either repair them on site or restore temporary power so you can keep running while we schedule a permanent fix. Emergency calls are handled the same day whenever possible.

Preventive Maintenance & Code Compliance

Regular maintenance keeps problems from becoming emergencies. We offer preventive maintenance contracts that include infrared thermal imaging to detect overheating connections before they fail, circuit testing and load analysis, equipment inspection, and code compliance reviews. For facilities with older electrical systems, we can conduct a full audit and recommend upgrades to meet current code.

Industries We Serve

Our commercial clients include property management companies, retail chains, restaurants and food service, medical and dental offices, manufacturing and warehouse facilities, schools and religious institutions, and multi-family residential complexes.

Retail & Shopping Centers

Retail spaces need reliable power, attractive lighting, and modern data infrastructure. We design buildouts that maximize visual appeal while keeping energy costs down. We handle lighting layouts that highlight products and create the right atmosphere, branch circuits for point-of-sale and office equipment, and security/camera system integration.

Restaurants & Food Service

Commercial kitchens have demanding electrical needs — heavy loads for cooking equipment, exhaust fans, refrigeration, and ice makers. We design three-phase circuits to handle it all, install dedicated circuits for each appliance, and ensure proper grounding for safety. We're also experienced with hood suppression system integration and emergency power for critical refrigeration.

Office Buildings & Corporate Spaces

Offices need clean, organized electrical distribution. We handle conference room AV integration, data and telephone cabling, lighting that reduces glare and eye strain, emergency lighting and egress paths, and HVAC control systems. For multi-floor buildings, we coordinate across stories and work with building management systems.

Warehouses & Distribution Centers

Warehouses need bright, reliable lighting across large floor areas, 3-phase power for material handling equipment (forklifts, conveyors), dock equipment power, and robust panel capacity for future expansion. We design overhead lighting systems that minimize shadows, install charging stations for electric forklifts, and build in flexibility for reconfiguration as operations evolve.

Manufacturing Facilities

Manufacturing operations depend on constant power and sophisticated electrical controls. We install main distribution panels, branch circuits for production machinery, motor control centers, emergency stops, safety interlocks, backup power systems, and predictive maintenance monitoring. We coordinate with plant engineers and equipment vendors to ensure everything integrates properly.

Medical Offices & Healthcare

Medical facilities have strict electrical code requirements — equipment must have dedicated circuits, emergency backup power is essential, and grounding and surge protection are critical. We understand NFPA 99 standards and healthcare-specific code amendments. We handle regular office circuits plus specialized circuits for imaging equipment, operating lights, monitor and charger circuits, and patient-grade power systems.

Schools & Educational Facilities

Schools and universities have diverse electrical needs — classrooms, labs, gymnasiums, auditoriums, cafeterias, and dormitories. We handle renovations, expansions, code compliance work, and emergency repairs. We understand the critical importance of completing work during summer or holiday breaks to avoid disruption to students and staff.

Hospitality & Events

Hotels, resorts, banquet facilities, and event venues need reliable power for guest rooms, kitchens, meeting spaces, and entertainment systems. We handle guest room electrical systems, ballroom lighting and AV integration, kitchen equipment, emergency egress lighting, and temporary power systems for events and exhibitions.

Why Commercial Clients Choose AAA

Licensed, Insured, BBB A+ Rated

We've been operating as a commercial electrical contractor in Connecticut since 2009. Our license (CT License #E1-0191759) is in good standing, we carry full liability and workers compensation insurance, and we're proud to hold a BBB A+ rating. When you hire AAA, you're working with a established, responsible contractor — not a startup or fly-by-night operation. We have deep relationships with building inspectors across New Haven and Fairfield counties, which helps us navigate permitting and inspections smoothly.

500+ Completed Projects

Seventeen years and 500+ completed projects means we've seen it all. We've wired restaurants, retail stores, offices, warehouses, manufacturing facilities, schools, medical offices, and multi-family residential properties. We understand the unique challenges of each industry and we know what can go wrong — and how to prevent it. That experience translates to faster timelines, fewer surprises, and higher quality work.

We Handle All Permits & Inspections

Most commercial contractors expect you to handle permit paperwork yourself. Not us. We prepare all permit applications, submit them to the building department, coordinate with Eversource for service changes, schedule inspections, and ensure everything passes on the first attempt. This is one of the biggest pain points for building owners and GCs — having a contractor that handles it all saves you time and headaches.

Owner-Operated — Not a Franchise

AAA is owner-operated by Jeff, a working electrician who's been in the business since day one. You're not dealing with a call center or franchise where decisions move slowly. When you need something, you can reach the owner. When there's a question or a change, you get a fast answer. That kind of accountability matters when your project is on the line.

Minimize Disruption to Your Operation

We understand that commercial clients can't afford downtime. For panel upgrades, we coordinate the timing carefully and can do load transfers in a single night to keep you operational. For buildouts, we work in phases and coordinate with other trades. For retrofits, we schedule work during off-hours or weekends. We make a plan with you upfront so you know exactly when work will happen and how it will impact your business.

Infrared Thermal Imaging & Predictive Testing

We have the equipment and training to perform infrared thermal imaging on electrical systems. This technology lets us spot overheating connections, loose terminals, and overloaded circuits before they become fires or failures. During major projects, we can use thermal imaging to do a baseline scan of your existing system and flag any issues that need attention.

Free Estimates & Competitive Pricing

We'll come to your facility, understand your project, ask questions about your goals and budget, and provide a clear, detailed estimate at no charge. We're competitive on pricing without cutting corners on quality. We can discuss payment options and phasing strategies to fit different budget scenarios.

One Contractor from Start to Finish

From the initial site visit and estimate through design, permitting, installation, testing, and final inspection, you deal with AAA. We coordinate with your GC, architect, electricians from other trades, and the building inspector — so you don't have to manage a hundred different relationships. That accountability and continuity makes projects run smoother.
