When something goes wrong with the power in your home or business, you need answers fast. A breaker that keeps tripping, an outlet that stopped working, lights that flicker every time the refrigerator kicks on - these are not problems to sit with. Commack Electrical Company takes calls around the clock, every day of the week, including nights, weekends, and holidays. Straight answers on the phone. Real electrical work. Quick to respond. Call us and the rest is handled.
Good electrical work isn't complicated, it's just done right, and it starts with finding the actual problem before touching anything else. When we arrive, we trace the fault from the symptom back to the source. A dead outlet might be a tripped GFCI device three rooms away. Flickering lights can point to a loose connection at the panel or a failing breaker. A burning smell from a switch or outlet is a sign that something is already overheating and needs attention now.
We handle the full range of residential and commercial electrical calls: outlets that have stopped working, breakers that trip repeatedly, sparking switches, no power in one room or half the house, and anything else that tells you the wiring is not behaving the way it should. Where GFCI and AFCI protection is missing or outdated, we bring it up to where it needs to be. Code-compliant wiring is the baseline on every job, not an upgrade. We'll trace it, fix it, and test it before we leave.
An older panel was sized for the electrical load of a different era. Modern homes run more circuits, more appliances, and more devices than the wiring in many Suffolk County houses was ever designed to support. When a panel is undersized, constantly tripping, or simply too old to carry the load safely, an upgrade is the right answer.
We handle 100-to-200-amp service upgrades, subpanel installation, and service-entrance and meter work. Load calculations are part of the process, so the new panel is sized for what the home or building actually needs, not just what fits the opening. Electrical work done to the standard the next inspection expects is how we approach every panel job. The rate is confirmed on the phone before anything is scheduled, so you know what you are looking at before we arrive. Reach out and we'll start at the panel.
Not every electrician works the same way, and the smaller jobs matter just as much as the big ones. A loose outlet, a switch that does not respond, a ceiling fan that wobbles or will not wire correctly, these are the calls we handle, and each one gets the same attention as a full rewire.
On the outlet and switch side, we install and replace standard outlets, GFCI outlets in kitchens and bathrooms, AFCI outlets where code requires them, USB outlets, dimmer switches, and standard light switch replacements. For lighting, we handle recessed and can lighting, under-cabinet lighting, security and motion sensor lights, flood lights, and outdoor landscape lighting. Ceiling fan installation and wiring is a common request, and we also wire bathroom and kitchen exhaust fans when a new fixture goes in or an old one needs replacing. Call and we'll handle the lights, outlets, and panel.
Whether a home needs a full rewire or a few new circuits added to an existing system, the work follows the same logic: the wiring has to carry the load without overheating, and every connection has to be grounded and bonded correctly.
We run dedicated appliance circuits for dryers, ranges, dishwashers, refrigerators, and any other equipment that needs its own protected path. New circuit installation for additions, finished basements, and sump-pump setups is a regular part of what we do. Whole-home surge protection pairs naturally with panel and rewiring work - it sits at the service entrance and protects everything downstream from voltage spikes that come in off the utility line. Partial rewiring is also an option when only a section of the home needs attention rather than the full house. Reach out and we'll start at the panel.
This area's panels, permits, and utility rules are familiar ground. Long Island's housing stock skews older, and the electrical systems inside those homes reflect it. At the same time, Suffolk County commuter households are adopting EVs at a fast clip, and nor'easters and summer storms make backup power a practical concern rather than a luxury. The three services below come up constantly in this area. Prompt response, even for last-minute electrical calls, is how we keep up with the demand.
Knob-and-tube wiring dates back to the early and mid-twentieth century, and a significant share of Commack's older homes still have it in the walls. It was never designed for grounded circuits, and it was not built to handle the loads a modern household puts on it. Many insurers flag it during a home inspection, and some will not write a policy on a house that still has it active. Aluminum branch wiring from the 1960s and 70s presents a different set of concerns - it expands and contracts with temperature changes, which can loosen connections over time. We replace both, running new copper wiring that meets current code and holds up under real-world use.
A Level 2 home charger runs on a dedicated 240-volt circuit and cuts charging time down to a fraction of what a standard outlet provides. Before any charger goes in, we check the panel for available capacity and run the load calculation to confirm the service can support it. If the panel needs a breaker added or the service needs an upgrade first, we handle that as part of the same job. Tesla home charger installation is one of the more common requests we see, alongside hardware from other manufacturers. The circuit is run to where the car parks, the charger is mounted, and the connection is tested before we leave.
When a nor'easter takes the grid down for two or three days, a generator is not a convenience - it is what keeps the sump pump running and the refrigerator cold. We install transfer switches and interlocks for both portable and standby generators, and we run the wiring for whole-home standby systems that start automatically when power goes out. The transfer switch is the critical piece: it isolates the home from the utility line so the generator feeds only the circuits it is meant to feed. We size the hookup to match the generator and the load it needs to carry.
From older homes to new commercial builds, the electrical system is what everything else depends on. Property managers, retail tenants, and office clients call us for the same reason homeowners do: something needs to work, and it needs to work correctly. A panel that cannot carry the load for a new tenant buildout, lighting that needs to be reconfigured for a new floor plan, outlets and circuits that were never added during the original construction - these are the calls we handle on the commercial side.
We do commercial panel upgrades, commercial wiring and circuit installation, commercial lighting, and commercial electrical repair. Wiring work checked against code before sign-off is the standard on every commercial job. Business continuity matters, and we scope the work on the call so you know what is involved before anyone shows up.
An electrical inspection gives you a clear picture of what the system is doing and where it falls short. We run them before a home sale, after a storm or power event, and for older homes where the wiring has not been looked at in years. Hard-wired smoke detector installation and carbon monoxide detector wiring are part of what we handle during an inspection visit when new devices are needed. If something is out of code or showing wear, it gets noted and explained before any work is scheduled.
Pricing for electrical work depends on what the job involves, and the only honest answer is the one you get after the scope is settled. When you call, you get a straight explanation of the rate and what it covers. Real answers. Real pricing. Real fast response.
No two panel upgrades are identical, and no two troubleshooting calls are the same. What you can count on is that the price is confirmed before anything is scheduled, and the scope is explained on the call so there is nothing to figure out after the fact. Ask what a job covers and you get a direct answer.
We take calls across Commack and the surrounding towns in Suffolk County. The service area includes Hauppauge, Smithtown, Kings Park, Nesconset, Dix Hills, Deer Park, Huntington Station, and Brentwood. Calls are answered any hour, any day, and availability is confirmed when you reach out.
Call (631) 426-2879 and we will walk through what the job involves on the phone.
We confirm the scope and the price before anything is scheduled, so you know what you are looking at before anyone comes out.
Yes. Calls are answered by someone who knows the trade and can talk through the job with you. We are available at any hour, any day of the week, including nights, weekends, and holidays.
The more detail you can share, the more accurate the phone quote will be. Describe the symptom, where it is happening in the home, and whether you know which circuit or panel breaker is involved. From there we can scope the job and confirm a rate before scheduling.
The price is confirmed on the call after the scope is established. If the job turns out to involve more once the work is underway, we explain what changed and why before continuing. You are not handed a number at the end that does not match what was discussed.
The rate covers the work described on the call. Ask what the visit includes and you will get a direct answer on the phone. We explain what is and is not in scope so there is nothing to untangle afterward.
Signs worth paying attention to include flickering lights, outlets that feel warm or discolored, breakers that trip repeatedly, or a panel that buzzes or runs warm to the touch. Homes in Commack and the surrounding area span a wide range of construction decades, and wiring from the mid-twentieth century often warrants a closer look. A call is the right starting point.
A repair addresses a specific fault, such as a dead outlet, a tripped breaker that will not reset, or a failing switch. A panel or service upgrade is a larger job that replaces the panel itself, increases the amperage the service can carry, or both. We scope both types of work on the call and confirm the price before scheduling.
We work with property managers and landlords across Commack and Suffolk County on both scheduled work and urgent repair calls.
Call (631) 426-2879 to talk through what your properties need and how we can handle the work.
If you need to leave access for someone who is not you, let us know on the call and we will work out the details. Clear access to the panel and the areas where the work is happening is the main practical requirement.
Commack Electrical Company is available around the clock - nights, weekends, and holidays included. Whether you are dealing with a fault right now or planning a panel upgrade, the call is where it starts. Code-compliant wiring on every job, from the first circuit to the final inspection. Not the biggest name in town. Just the one that answers. No runaround.

Below is a plain-language look at the electrical work we handle across Commack and the surrounding Suffolk County area. Each row covers what the service involves, who it fits, and one practical thing worth knowing before you call. If you do not see your situation listed, call us and we will tell you where it falls.
| Electrical Service | What the Job Involves | When You Need It | What to Keep in Mind |
|---|---|---|---|
| Ceiling Fan Installation | New fan installation where no fixture exists, Fan-rated box replacement, Old fan removal and swap, Switch and remote wiring | Rooms with an existing light fixture or no overhead wiring at all | If the ceiling box is not rated to support a fan's weight and movement, we replace it before the new fan goes up. Skipping that step is a common cause of fan failures. |
| Lighting Installation | Recessed and LED retrofit lighting, Under-cabinet and accent lighting, Exterior and security lighting, Switch and dimmer connections | Homeowners upgrading fixtures, adding lighting to a remodel, or improving outdoor security | Outdoor security lighting runs off dedicated or existing outdoor circuits depending on the load. We confirm which approach fits your setup before running any wire. |
| Dedicated Appliance Circuits | 240-volt circuits for ranges and dryers, Circuits for refrigerators and dishwashers, Workshop and garage circuits, Breaker sizing to match the appliance | Any major appliance that needs its own circuit rather than sharing a general-use branch | Running a high-draw appliance on a shared circuit is one of the more common causes of repeated tripping. A dedicated circuit sized to the load solves it cleanly. |
| Backup Generator Installation | Transfer switch installation, Generator-to-panel wiring, Circuit selection for generator load, Utility-safe hookup and testing | Homes in Suffolk County that lose power during nor'easters and ice storms | A transfer switch is required by code and is not optional. It isolates the home from the utility line so the generator cannot back-feed onto lines being worked by utility crews. |
| Electrical Safety Inspections | Panel and breaker condition review, Grounding and bonding check, Outlet and wiring assessment, Documentation of findings | Home buyers, sellers, and owners of older homes that have not been inspected recently | An inspection is a good starting point before a rewiring project too, since it maps what is in the walls before the scope is confirmed. |
| Wiring & Circuit Installation | New circuit runs from the panel, Partial and whole-home rewiring, Wiring for additions and remodels, Rough-in and finish wiring | Renovations, additions, and homes where the existing wiring cannot support the planned layout | Permit and inspection requirements depend on the scope of the wiring work. We confirm what applies at your address before scheduling. |
| Outlet & Switch Installation | GFCI and AFCI outlet installation, USB and specialty outlet replacement, Dimmer and smart switch wiring, Code-location compliance | Kitchens, bathrooms, garages, and any room with outdated or missing protection | GFCI protection is required by code in specific locations. If your home predates those requirements, we identify which outlets need upgrading during the visit. |
| Electrical Panel Upgrades | Load calculation and service assessment, Fuse box to breaker panel conversion, Subpanel installation, Meter and service entrance upgrade | Older homes adding load, or any property where the panel cannot keep up with demand | Electrical work done to the standard the next inspection expects is how every panel job gets handled. We confirm permit requirements before the work starts. |
| EV Charger Installation | Level 2 charger circuit installation, Panel capacity check and breaker addition, 240-volt dedicated circuit run, Charger mounting and connection | Homeowners adding an electric vehicle and needing a proper home charging setup | If the panel does not have room for the added breaker or the service amperage is already near capacity, we handle the panel work as part of the same job. |
| Breaker & Fuse Repair | Breaker replacement and reset diagnosis, Fuse box troubleshooting, Overloaded circuit identification, Double-tapped breaker correction | Homes where a breaker trips repeatedly or a fuse blows under normal load | A breaker that keeps tripping often points to a wiring fault or an undersized circuit, not just a weak breaker. We check both before swapping parts. |
| Electrical Repairs & Troubleshooting | Dead outlets and tripped breakers, Flickering or dimming lights, GFCI and AFCI fault tracing, Circuit testing and verification | Any home or commercial space with an unexplained electrical fault | We trace the fault to its source before replacing anything, so the fix addresses the actual cause rather than a symptom. |
| Knob-and-Tube & Aluminum Rewiring | Knob-and-tube circuit identification and replacement, Aluminum branch wiring remediation, Whole-home rewiring from the panel out, Code-compliant wiring on every job | Mid-century Long Island homes with original or partially modified wiring | Aluminum wiring risk concentrates at the connections and junctions where aluminum meets copper. Remediation targets those points specifically rather than replacing wire that is still performing correctly. |
| Whole-Home Surge Protection | Panel-level surge device installation, Protection for hardwired appliances, Coordination with existing panel capacity, Post-storm protection review | Homes in areas with frequent outages and power restoration surges | A power strip protects only what is plugged into it. Panel-level protection intercepts voltage spikes at the service entrance before they reach any circuit in the house. |
| Code-Correction Wiring | Pre-sale code violation correction, Unpermitted work brought to code, Aluminum-to-copper connection remediation, Inspection-ready documentation | Homeowners preparing for a sale, inspection, or insurance review | Work in this area gets done to the code inspectors here actually enforce. We scope corrections on the call so you know what is involved before we schedule. |
| Basement & Sump-Pump Circuits | Dedicated sump pump circuit installation, Backup sump circuit wiring, Basement outlet and lighting circuits, GFCI protection in wet locations | Homes with finished or active basements where moisture and load demand require dedicated wiring | A sump pump sharing a general circuit can lose power at the worst moment. A dedicated circuit with GFCI protection in a wet location is both safer and code-correct. |
