A&H Electrical Services has been the electrician Essex homeowners and Baltimore County businesses call when the work has to be done right. Founded in 1989, we started as a small family operation and have grown into a full-service electrical contractor serving the whole county, from single-family homes to commercial properties and everything in between. Whether you need a local electrician for a quick repair or an electrical contractor near me search that lands on someone with real roots in the community, you have found the right crew. We show up, and we keep you posted until the job is done. Local crew. Real electrician on the phone. Quick to respond.
Staying ahead of electrical problems keeps your home safe. Flickering lights, dead outlets, tripping breakers, a burning smell near a panel or outlet, a sparking receptacle, or a room that has simply lost power are all calls we take every single day. These problems are not always dramatic, but they are never something to put off. A flickering light can point to a loose connection. A breaker that trips repeatedly can signal a circuit that is overloaded or failing. A burning smell is always worth a same-day call.
When we arrive, we start by listening to what you have noticed, then we trace the problem back to its source. Our electricians check grounding and bonding, test GFCI and AFCI protection, and look at the full circuit before calling anything resolved. We do not patch symptoms and leave. We find the cause and fix it.
Trusted by local homeowners and property managers for their electrical work, we handle repair calls across Essex and the surrounding area, and we are available for urgent situations when waiting is not an option. Call and we'll get you back to full power.
Your home deserves wiring that is safe and up to code, and that starts at the panel. Electrical panels wear out over decades of use, and older panels are often simply too small for the demands of a modern home. If your panel is still using fuses, if breakers are tripping without a clear cause, or if you are adding major appliances, an EV charger, or a home addition, it is time to look at whether your service can carry the load.
We handle 200-amp service upgrades, fuse box replacements, circuit breaker replacements, subpanel installation, and service-entrance and meter upgrades. Before any panel work begins, we run load calculations to make sure the new service fits the actual demand of your home or building. For commercial clients, we work through the same process at a larger scale, coordinating with the utility and pulling the necessary permits.
We give you straight answers about your panel and wiring, no surprises. You will know what the job involves, what it costs, and what to expect before we start. Reach out and we'll start at the panel.
Our electricians know the homes and wiring in this area, and a lot of those homes carry history in their walls. Knob-and-tube wiring from the early 1900s, aluminum wiring from the 1960s and 1970s, and patchwork additions done over the decades are common in older Essex and Baltimore County neighborhoods. Knob-and-tube replacement and aluminum-wiring remediation are not just upgrades. They are safety corrections that bring a home into line with current code and reduce real risk.
Beyond rewiring older homes, we run new wiring for additions and remodels, install dedicated appliance circuits for dryers, ranges, dishwashers, and refrigerators, and wire workshops, garages, and basement spaces including sump-pump circuits. All wiring work is code-compliant, and we install arc-fault and ground-fault breakers where required. Work is performed by licensed electricians who know the local inspection process and pull the right permits from the start. Call and we'll handle the lights, outlets, and panel.
Our customers call us back because we make wiring simple, and nowhere is that more visible than in the everyday upgrades that change how a home feels and functions. Inside, we install recessed and LED lighting, under-cabinet lighting, dimmer switches, and ceiling fans with proper wiring and bracing. Outdoors, we run security lighting, motion-sensor fixtures, and weatherproof exterior outlets that hold up through Maryland winters and humid summers alike.
Outlet and switch work covers everything from a single GFCI outlet in a bathroom or kitchen to a full outlet layout for a finished basement or garage. We also install exterior outlets for decks, patios, and driveways where a weatherproof, code-correct installation matters.
We are locally owned and operated electricians, and we take the same care on a ceiling fan swap as we do on a full panel upgrade. Every job gets done cleanly, and every outlet and fixture gets tested before we leave.
Getting your electrical problem handled starts with a quick call, and the same is true when you are planning ahead rather than reacting to a problem. EV charger installation and backup generator hookups are two of the most common forward-looking electrical projects we handle for Essex and Baltimore County customers.
For EV chargers, we install Level 2 charging circuits including the dedicated circuit, the panel capacity check, and the permit. Whether you drive a Tesla or any other electric vehicle, the process starts at the panel and ends with a properly wired, code-compliant outlet or hardwired unit in your garage or driveway.
For generator work, we install transfer switches and connect standby or portable generators to your home's electrical system so that a power outage does not leave you without heat, refrigeration, or lighting. We also install whole-home surge protection at the panel level, which guards your appliances and electronics from voltage spikes that come in through the utility line. EV charger circuits, surge protection, and generator hookups all live on the electrical side of the house, and that is exactly where we work.
Getting your electrical problem handled starts with knowing what you actually have. An electrical safety inspection gives homeowners, buyers, sellers, landlords, and property managers a clear picture of the condition of a home's wiring, panel, outlets, and grounding. We check the panel for proper breaker sizing and signs of wear, test outlets for grounding and GFCI protection, look for code violations, and flag anything that poses a safety concern.
Pre-purchase electrical inspections are especially useful in older Baltimore County homes where the wiring may not have been touched in decades. Troubleshooting and diagnostics are part of every inspection we run. You get a plain-language summary of what we found and what, if anything, needs attention. Prompt response, even for last-minute electrical calls, means we can often schedule an inspection quickly when a real estate timeline is tight.
Essex is home base, and Baltimore County is where we work every day. We serve homeowners, landlords, property managers, and commercial clients across the county, including Middle River, Rosedale, Dundalk, Parkville, White Marsh, and Edgemere. If you are in the surrounding area and need a residential or commercial electrician near me, we are close by and ready to schedule.
Same-day service is available for urgent situations, and we are reachable around the clock for electrical emergencies. Trusted by local homeowners and property managers for their electrical work across this part of Maryland, we have built our reputation over 37 years by showing up when called and doing the job right the first time.
Every job we take on is done to code. That is not a slogan. It is how we protect you, your property, and the people who live or work in it. Permits get pulled when required. Inspections get scheduled. Work is done by licensed electricians who know the local codes and do not cut corners to move faster.
Code-compliant wiring matters when you sell your home, file an insurance claim, or simply want to know the work was done correctly. We do not leave you guessing. Before we close up a wall or button up a panel, we make sure everything meets current standards and that you understand what was done and why.
We have been doing this since 1989, and our reputation in Essex and Baltimore County is built job by job. If something is not right after we leave, we want to know about it. We are not satisfied until you are, and if a problem traces back to our work, we will come back and make it right. That is not a formal guarantee. It is just how we operate.
We have been doing this work since 1989, which means we have been in Essex and the surrounding communities for 37 years. That history is built job by job, and we are still here because we stand behind the work we do.
We are locally owned and operated electricians, which means the people answering the phone and showing up at your door are part of this community. We are personally accountable for every job we take, and our reputation in Baltimore County depends on getting it right.
Yes, and it shapes how we approach every job. Essex and the surrounding neighborhoods have a significant share of pre-1950s and mid-century homes, and we have worked in enough of them to know what to look for, from knob-and-tube wiring to undersized panels and aluminum branch circuits.
We stand behind what we do. If a problem traces back to our work after we leave, we will come back and make it right. That is not a printed policy, it is just how we have operated since 1989.
We give you a clear estimate before any work starts and walk you through what the job involves, including permit and inspection costs where they apply. You will not see a number on the invoice that we did not discuss with you first.
We work cleanly and take precautions to protect your floors, walls, and finishes while we are on the job. Before we leave, we clean up the work area so the space looks the way we found it, minus the electrical problem.
We diagnose the issue, explain what we found, and tell you what actually needs to happen. If something else comes up during the job that is worth knowing about, we will mention it, but we do not push work that is not necessary.

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.
