A&H Electrical Services has been handling electrical work for Essex homeowners, landlords, and businesses since 1989. When something goes wrong with your wiring, your panel, or your outlets, you want someone who knows the area and can get there fast. Local crew. Real electrician on the phone. Quick to respond.
We serve the full range of residential and commercial electrical needs across Essex and Baltimore County, from quick repairs to full rewiring projects. We show up, and we keep you posted until the job is done. As locally owned and operated electricians, we take every job personally, whether it is a single tripped breaker or a whole-home panel upgrade. Call and we'll get you back to full power.
Our electricians know the homes and wiring in this area, and that experience shapes how we approach every job. Whether you manage a rental property, own a small business, or just bought your first home, the electrical work gets done right the first time. We are trusted by local homeowners and property managers for their electrical work, and we aim to keep it that way on every call we take.
Staying ahead of electrical problems keeps your home safe. Dead outlets, flickering lights, and breakers that trip repeatedly are not just annoyances. They are signs that something needs attention. Our electricians trace the problem to the source, explain what they find, and make code-compliant repairs before they leave. We handle GFCI and AFCI protection upgrades, arc-fault and ground-fault breaker replacements, and circuit diagnostics for homes and commercial spaces alike. Call and we'll handle the lights, outlets, and panel.
We install and replace outlets of all types, including GFCI-protected outlets in kitchens and bathrooms, AFCI outlets for bedrooms, and USB-integrated outlets where you want them. Switch and dimmer replacements are quick jobs we do every week. On the lighting side, we handle recessed lighting, pendant and chandelier installation, under-cabinet lighting, and outdoor security and motion-sensor lights. If you want landscape lighting or a new fixture in any room, we can wire it properly and make sure it is on the right circuit.
New ceiling fan installation often requires running a dedicated switch leg or adding a new junction box rated for fan weight. We handle that correctly so the fan operates safely for years. We also wire bathroom exhaust fans and attic fans, which are important for moisture control and air quality in older Maryland homes. If you need a fan replaced or installed from scratch, it is a straightforward call.
Your home deserves wiring that's safe and up to code, and that starts with a panel that can handle today's electrical loads. Older homes in the Essex area frequently come with 60-amp or 100-amp service that was never designed for modern appliances, home offices, or EV chargers. We give straight answers about your panel and wiring, no surprises, so you know exactly what needs to happen before any work begins.
We upgrade electrical panels to 200-amp service and handle service-entrance and meter upgrades when the utility connection needs to match the new panel capacity. Main panel replacements, subpanel installations, and commercial panel upgrades are all work we do regularly. A load calculation before the upgrade ensures the new panel is sized correctly for your actual usage, not just the minimum code requirement.
Large appliances need their own circuits. Dryers, electric ranges, refrigerators, and similar loads should never share a circuit with other outlets. We run dedicated circuits sized for the specific appliance and install the correct 240V or 220V outlet where needed. We also wire dedicated circuits for sump pumps and basement equipment, which is practical and important in a region that sees significant rainfall and occasional flooding. Reach out and we'll start at the panel.
Essex sits in a part of Maryland where the housing stock runs deep, storm season is real, and EV ownership is growing fast. The electrical work that comes up here reflects all of that. Below are three services we handle regularly for homes and properties across the area.
Many homes in Essex and the surrounding neighborhoods were built before 1960, and a significant number still have knob-and-tube wiring or aluminum branch wiring running through the walls. Knob-and-tube lacks a ground conductor and cannot safely support modern loads. Aluminum branch wiring, installed widely in the 1960s and 1970s, expands and contracts with heat in ways that create loose connections and fire risk over time. We perform whole-home rewiring and targeted aluminum-wiring remediation, and we can conduct an electrical safety inspection first to document exactly what is there. Many insurers in Maryland now require updated wiring before they will issue or renew a policy on an older home, so addressing it is both a safety and a practical financial matter.
Baltimore County has one of the higher rates of EV adoption in the state, and the demand for home Level 2 charger installation has grown steadily. A Level 2 EVSE requires a dedicated 240V circuit sized for the charger's amperage, typically 40 to 50 amps. We assess your current panel capacity, run the circuit to the garage or driveway, and install the outlet or hardwired connection the charger needs. If your panel needs an upgrade to accommodate the new circuit, we handle that as part of the same project.
Nor'easters, ice storms, and summer thunderstorms knock out power across the Mid-Atlantic region every year, and Essex is not immune. A backup generator connected through a proper transfer switch keeps your lights, refrigerator, sump pump, and critical circuits running when the grid goes down. We install generator transfer switches and handle all the wiring between the generator and your panel. We work with portable generator hookups as well as permanent standby generator wiring. One number. One call. One electrician at your door.
Getting your electrical problem handled starts with a quick call. But sometimes the right move is a full inspection before a problem develops. We perform electrical safety inspections for home purchases, aging properties, and situations where an insurer or landlord needs documentation of the system's condition. We check panel condition, grounding and bonding, wiring type, outlet protection, and overall code compliance.
Whole-home surge protection is a single device installed at the panel that shields your appliances and electronics from voltage spikes caused by lightning, utility switching, or large motors cycling on and off. We also install hard-wired smoke and carbon monoxide detectors where code requires them or where a homeowner wants reliable, permanent protection. We offer prompt response, even for last-minute electrical calls, so if something comes up before a closing or a tenant move-in, we can usually get there quickly.
Our customers call us back because we make wiring simple, and part of that is being upfront about cost and scheduling. We offer same-day availability for many jobs, and we respond promptly when something urgent comes up. Before any work begins, we explain what we found, what needs to happen, and what it will cost. You get a clear estimate and an honest timeline, not a number that changes after the fact. Call for a quote and we'll give you a straight answer on what the job involves.
Our electricians know the homes and wiring in this area, and that same knowledge carries into commercial work. We handle electrical projects for property managers, office tenants, retail operators, and small businesses across Baltimore County. Commercial panel upgrades, tenant improvement wiring, and office electrical work are all part of what we do. If you manage a property or run a business and need an electrician who can work around your schedule, give us a call.
We work throughout Essex and the communities around it, including Middle River, White Marsh, Rosedale, Dundalk, Parkville, Nottingham, and Bowleys Quarters. Whether you are in a neighborhood close to the water or further inland in Baltimore County, we can get an electrician to you without a long wait. If you are not sure whether we cover your address, call and ask. We will tell you directly.
Call (667) 442-8789 and tell us what you are dealing with. We gather the details on the call, give you a clear estimate, and get you on the schedule, often the same day for repairs and troubleshooting.
Yes, same-day availability is something we offer for many jobs, including repairs, outlet work, and troubleshooting calls. If you call early in the day, there is a good chance we can get an electrician to you before the end of the afternoon.
Stop using the outlet or circuit immediately and do not reset the breaker if the panel feels hot or smells like burning. Call us at (667) 442-8789 so we can assess whether this needs same-day attention, which it usually does.
We confirm the details of your job, give you an estimate, and set a time that works for your schedule. When the electrician arrives, they will walk through what you have noticed, diagnose the problem at the source, and explain what needs to happen before any work begins.
A brief description of the problem helps, including which outlets, switches, or circuits are affected and whether you have noticed any smells, sounds, or visible damage. If you know the age of your home or panel, that is useful too, though we can figure it out once we arrive.
A breaker that trips repeatedly is telling you something is wrong, whether that is an overloaded circuit, a failing breaker, or a wiring fault. Continuing to reset it without finding the cause can damage appliances and create a fire risk, so the right move is to call us and let an electrician trace the problem.
Check your panel first to see if a main breaker has tripped, and check whether your neighbors have power to rule out a utility outage. If the panel looks fine and the outage is isolated to your home, call us and we will walk you through the next steps and get someone out to you.
We arrive, listen to what you have noticed, and inspect the affected outlets, switches, or panel. Once we identify the cause, we explain what we found and what the repair involves before we start any work, and we test everything before we leave.
Yes. Every job we do is code-compliant, and we pull permits and schedule inspections when the work requires them. Work is performed by licensed electricians who know the local codes and do not skip steps to move faster.

How do I know if my panel needs an upgrade?
Common signs include breakers that trip frequently without an obvious cause, lights that dim when large appliances run, a panel that feels warm to the touch, or a home still running on 60-amp or 100-amp service. If you are planning to add an EV charger, a home office, or major appliances, a load calculation will tell you whether your current panel can handle the added demand. Call us and we will walk you through what we find.
What causes a breaker to trip repeatedly?
Repeated tripping usually points to one of three things: a circuit that is carrying more load than it was designed for, a failing breaker that no longer holds its rating, or a wiring fault somewhere on the circuit. Resetting the breaker without finding the cause can damage appliances and create a fire risk. We trace the problem to the source before making any repair.
Is the electrical work permitted and inspected?
Yes. We pull permits and schedule inspections for any work that requires them under local and state code. That documentation protects you when you sell the home or file an insurance claim. Work is performed by licensed electricians who follow the current National Electrical Code and any local amendments that apply in Baltimore County.
Work Performed by Licensed Electricians
Every job we take is handled by licensed electricians who know the local codes and do not skip steps to move faster. We pull permits and schedule inspections when the work requires them.
How do I know if my older home needs a rewire?
If your home was built before 1960, there is a reasonable chance it still has knob-and-tube wiring. Homes built in the 1960s and 1970s may have aluminum branch wiring. Both present risks that modern wiring does not. Signs include outlets that are warm to the touch, a burning smell with no visible source, breakers that trip in areas of the home that do not seem overloaded, or an insurer who has flagged the wiring on a policy review. An electrical safety inspection gives you a clear answer.
What does EV charger installation involve?
A Level 2 home charger requires a dedicated 240V circuit, typically rated at 40 to 50 amps depending on the charger. We start by assessing your current panel to confirm it has the capacity for the new circuit. If the panel needs an upgrade first, we handle that as part of the same project. We run the circuit to your garage or driveway, install the outlet or hardwired connection, and test the setup before we leave.
What size generator do I need, and how does the hookup work?
Generator sizing depends on which circuits you want to keep running during an outage, such as your refrigerator, sump pump, lights, and a few outlets. We can help you think through the load before you purchase a generator. On the installation side, we wire the transfer switch and connect it to your panel so the generator feeds only your circuits and cannot backfeed onto utility lines. We work with both portable generator hookups and permanent standby wiring.
Experienced With Older and Newer Homes
We work on homes built in every decade, from pre-war construction with knob-and-tube wiring to new builds adding EV chargers and smart lighting. That range of experience means fewer surprises once we open the walls.
Do I need to be home during the electrical work?
For most jobs, yes. We need access to the panel, the affected outlets or circuits, and often the attic or crawl space. If you manage a rental property and cannot be on-site, a tenant or property representative who can provide access and answer questions about the space works fine. We confirm all of that when we schedule.
How does pricing work, and will I get an estimate before work starts?
Yes. Before any work begins, we explain what we found, what the repair or installation involves, and what it will cost. You get a clear number upfront. We do not give you one figure and then adjust it after the fact. Call us for a quote and we will give you a straight answer on what the job involves.
Upfront Quotes With No Surprise Fees
We explain what we found and what the work will cost before anything begins. The number we give you at the start is the number you pay at the end.
Can you get to me the same day for an urgent electrical problem?
We offer same-day availability for many jobs, including repairs, troubleshooting, and outlet work. If you call early in the day, there is a good chance we can get an electrician to you before the end of the afternoon. For situations involving a sparking outlet, a panel that smells like burning, or a circuit that is hot to the touch, call us right away and we will assess whether same-day service is needed, which it usually is.
What does whole-home surge protection actually do?
A whole-home surge protector is a single device installed at your electrical panel. It absorbs voltage spikes caused by lightning strikes, utility switching events, and large motors cycling on and off, before that excess voltage reaches your appliances and electronics. It does not replace outlet-level surge strips for sensitive equipment, but it provides a first line of defense for every circuit in the home.
What are the risks of aluminum branch wiring in an older home?
Aluminum expands and contracts more than copper as it heats and cools. Over time, that movement loosens connections at outlets, switches, and breakers. Loose aluminum connections can arc and generate heat in ways that are not always obvious from the outside. Remediation options include installing approved connectors at every device location or, in some cases, rewiring the affected circuits with copper. An inspection tells you what is present and what the best path forward looks like.
