Electrical work in Mercer County's college town

Greenville sits in northern Mercer County where the Shenango River winds through a town built on manufacturing and anchored by Thiel College. Brick storefronts line Main Street, historic homes climb the hillsides, and the surrounding townships mix farms with newer subdivisions. Electrical Service Precision Pros wires all of it — from century-old wiring to modern service upgrades.

Your electricity comes from Penn Power, a FirstEnergy company serving Greenville and Mercer County. Penn Power owns the lines, the poles, the transformers, and your meter. Everything from the meter into your home is yours to maintain — the service entrance, the panel, and every circuit.

Northwest Pennsylvania winters are the real test here. Lake-effect snow, ice, and deep cold snap limbs onto lines and push heating systems to their limits. We install standby generators that keep the furnace running through outages, storm-harden service entrances, and make sure panels can carry the heating load without tripping.

The housing stock is old and proud of it: Victorian-era homes, early-1900s doubles, and mid-century ranches. Knob-and-tube hides in the oldest walls, aluminum branch wiring shows up in the 60s and 70s builds, and fuse boxes still serve some homes. We modernize these systems methodically — safety first, charm intact.

Thiel College brings student rentals to the mix, and rentals have their own electrical demands: hard-used panels, aging wiring, and the need for everything to simply work. We keep rental properties safe and reliable for owners and tenants alike.

When you call Electrical Service Precision Pros, you get electricians who know Greenville — the college hill, the river streets, the township roads. We show up on time, explain the work in plain language, and leave your home cleaner than we found it.

Our electrician team at work on a home service call

Who we are

A Mercer County crew for old homes and hard winters

We started this company because Greenville's old homes needed electricians who respect them. Every crew member here has fished new wire through plaster walls, replaced a fuse box without disturbing the woodwork, and gotten a furnace back online during a January outage. Our work covers the full residential range: rewiring, panel upgrades, generators, EV chargers, lighting, and troubleshooting. Historic-home expertise and winter readiness are our specialties — the two things Greenville demands most. We're based in Mercer County and we drive these roads daily. When lake-effect snow takes down the lines, we're already nearby. After the work is done, we walk you through everything and label the panel so the next winter finds you ready.
  • •Old-home respect: We modernize wiring without destroying what makes the house special.
  • •Winter readiness: Generators, storm-hardened entrances, and panels that carry the heating load.
  • •Written prices: Scope and cost agreed before we start; the invoice matches.
  • •Code-clean work: Everything meets current code and passes inspection.
  • •Tidy job sites: Drop cloths, shoe covers, and a full cleanup every visit.
  • •Plain talk: We explain what's wrong and what it costs in words that make sense.

Why Greenville calls us

What sets our crew apart in town

•Historic-home rewiring: Knob-and-tube, plaster walls, and fuse boxes are our daily work. We bring old homes current with minimal disruption.
•Winter generator expertise: We size standby generators for the furnace, the well pump, and the essentials — the loads that matter when it's ten below.
•Penn Power coordination: We handle the utility side of service upgrades — disconnects, reconnects, and meter work — so you deal with one contractor.
•Doubles and rentals: Shared services, divided panels, and hard-used rental wiring — we sort out multi-unit electrical cleanly.
•Aluminum wiring remediation: The county's 60s and 70s homes are full of it. We fix the connections with approved methods.
•Fast local response: We're in the county, not in Pittsburgh. When the storm hits, we're already close.

Electrical problems we fix in Greenville

Knob-and-tube in the oldest homes

Greenville's earliest homes still carry knob-and-tube: no ground wire, insulation buried over conductors, and connections made a century ago. We replace it systematically, prioritizing the highest-risk runs — kitchens, baths, and anywhere insulation now covers the old wire.

Furnaces tripping breakers in January

When the deep cold hits, furnaces and backup heat run constantly, and marginal panels give up. We verify the furnace circuit is dedicated and correctly sized, check the panel's capacity, and make sure the heating load doesn't take down the house.

Storm-damaged service entrances

Ice and lake-effect snow load up limbs that tear at masts and drops. A leaning mast or frayed drop is a hazard and a common cause of partial power after storms. We repair service entrances and coordinate with Penn Power wherever their lines are involved.

Fuse boxes still in service

Some Greenville homes still run on fuse boxes — and while fuses work, the boxes are undersized for modern loads and often show their age in corroded contacts. We replace them with modern breaker panels, usually in a single day, with proper labeling throughout.

Aluminum branch wiring

Homes from the 60s and 70s often have aluminum branch circuits whose connections loosen as the metal cycles. We remediate with approved methods that make the wiring safe without the cost of a whole-house rewire.

Shared electrical in doubles

Greenville's doubles often share a service, a panel, or a tangle of circuits between units. We separate services cleanly, give each unit its own panel and metering setup, and untangle the shared circuits so each side stands alone.

Client Experience

What to Expect Working With Us

"They rewired our 1910 house room by room without tearing up the plaster. The knob-and-tube is gone, every room has grounded outlets now, and the woodwork is untouched. Craftsmen, not just electricians."

- Historic homeowner

"Our double shared one ancient panel between both units. They separated the services cleanly, gave each side its own panel, and sorted out decades of tangled circuits. Both units finally make sense electrically."

- Double owner

"The standby generator went in before winter and the first big snowstorm proved it — furnace, well pump, everything stayed on while the neighborhood went dark. They sized it right and handled the Penn Power coordination."

- Township homeowner

Frequently Asked Questions

Penn Power, a FirstEnergy company, delivers electricity to Greenville and Mercer County. When the power goes out, Penn Power restores the grid; we handle everything from the meter inward — the service entrance, the panel, and every circuit.
Yes. Service upgrades, meter work, and storm-damage repairs all touch Penn Power's equipment at some point. We handle the scheduling, the disconnect and reconnect, and the inspection coordination. You deal with one contractor — us.
It depends on the service size and the existing loads. We do a load calculation on your actual usage — many Greenville homes still sit on 100-amp services. If there's headroom, we wire the Level 2 charger on a dedicated circuit; if not, we discuss the upgrade first.
For most homeowners here, yes. Lake-effect snow and ice take down lines every winter, and outages can last days. A standby keeps the furnace, the well pump, and the fridge running automatically. After the first winter storm, nobody questions the investment.
Panel upgrades, service changes, generator installs, and rewiring generally need permits and inspections. We handle the application and the inspector walkthrough. Small repairs like replacing a broken switch usually don't — and we'll tell you which is which.
With an inspection that maps what's actually in the walls — knob-and-tube, early NM cable, ungrounded circuits, and the panel's condition. We rank everything by risk and build a phased plan: the dangerous stuff first, the nice-to-haves later. Most old homes don't need everything done at once.
It's manageable, not a crisis. The issue is connections loosening over time as the aluminum expands and contracts. We inspect the connections and remediate with approved methods, prioritizing kitchens and high-load circuits. Most homes need remediation, not a rewire.
It can be. Panels from certain eras have breakers that don't trip reliably, and old panels run out of space long before they run out of years. Signs of trouble include warm breakers, scorch marks, and frequent nuisance trips. We inspect honestly — if the panel is sound, we'll say so.
Usually the furnace circuit is shared with too much else, the breaker is weakening from years of heating cycles, or the blower motor is drawing more current as it ages. We test the circuit's actual load, check the motor, and make sure the furnace has the dedicated circuit it needs.
Yes. Finished basements need receptacles on proper spacing, good lighting, and dedicated circuits for entertainment gear or a home office. In older Greenville homes we also check that the panel has room — basement finishes often push a full panel over the edge.
Whole-home surge protection at the panel is the foundation — it clamps the big spikes before they reach your wiring. Proper grounding matters just as much; we verify the grounding electrode system too. For the full picture, we add point-of-use protectors at sensitive electronics.
In most cases, yes. Fuse boxes served their era, but they're undersized for modern loads, replacement fuses get harder to find, and the old boxes often show corrosion. A breaker panel gives you more capacity, better protection, and room to grow — usually installed in a day.
Usually, yes. We fish new wire through walls and ceilings with strategic access points — small openings we patch afterward — rather than gutting rooms. Plaster walls take more finesse than drywall, and that's exactly the work we do every week.
A hot smell from the panel means something is overheating — a loose connection, an overloaded breaker, or a failing component. Turn off what you can and call promptly; this is one of the few electrical symptoms that shouldn't wait. We find the heat source with thermal inspection and fix it.
Yes. Detached garages need a feeder from the main panel run underground in conduit, usually with a sub-panel in the garage. We size the feeder for the tools, the lighting, and the EV charger you'll eventually want — because everyone eventually wants one.
Yes — and it's the only safe way to connect one. A transfer switch or interlock keeps generator power off the grid, protecting line workers and your equipment. We install the switch, wire the inlet box, and show you the safe connection sequence for storm season.
The compressor draws a big starting surge, and on a marginal service the lights show it. Occasional slight dimming is common, but pronounced dimming points to a loose connection or an undersized service. We test and tell you which it is.
Yes. We install a fan-rated box that carries the weight — the existing light box usually can't — then wire the fan with separate fan and light control. Bedrooms are the best room for a fan; you'll feel the difference on the first warm night.
A three-prong outlet doesn't promise a ground — plenty of Greenville's older homes have three-prong outlets wired without one. A simple tester tells the story in seconds. We test every outlet, add real grounding where the wiring allows, and protect the rest with GFCIs.
Yes. Home offices need dedicated circuits for the computer setup, good lighting for video calls, and surge protection for the equipment. We add what the room needs without overloading the circuits it already has.
Usually weak Wi-Fi at the door, an underpowered transformer, or both. Video doorbells need more power than old chime transformers deliver. We upgrade the transformer, check the wiring, and make sure the camera gets the steady power and signal it needs.
Yes. We install dusk-to-dawn floods, motion-sensor security lights, and low-voltage landscape lighting — all with LED fixtures that sip power. Good outdoor lighting is part security, part curb appeal, and we design for both.
Yes. Screened porches need weather-resistant receptacles, proper lighting, and often a ceiling fan — all wired for the damp environment. We run the circuits from the house panel, use outdoor-rated devices, and make sure everything is GFCI-protected where it should be.
The alarm means water is rising faster than the pump handles, the float is stuck, or the pump has failed. Check that the pump has power and the discharge isn't frozen — a real risk in January. If the alarm keeps sounding, call us; a pump that can't keep up is an emergency.
Yes. Hot tubs need a dedicated GFCI-protected circuit sized for the heater and pumps, with the disconnect in sight of the tub at proper distance. We run the circuit, set the disconnect, and verify the deck can carry the filled tub's weight — the part people forget.
At least once a year, ideally in the fall before winter. We change the oil and filter, check the battery and coolant, test the transfer switch, and run the unit under load. A generator that hasn't been serviced is a decoration, not backup power.
