Do you sell generators or just install them?

We're an installation contractor, not a dealer. You can buy from any reputable supplier; we recommend Generac and Kohler for standby units.

How long does install take?

Most whole-home standby installs are 1–2 days of electrical work, plus a separate gas hookup and a county inspection.

Will the generator run my whole house?

Depends on the size. A 22 kW unit will run most 2,000–3,000 sq ft homes including A/C. Smaller units use a sub-panel for essentials only.

Are you licensed to do generator install in Great Falls, VA?

Yes. Pirro Electric is fully licensed and insured to perform commercial and residential electrical work in Maryland, Virginia, and Washington, D.C., including Great Falls. We pull all required permits and coordinate inspections with the local jurisdiction on every job.

Do you handle aluminum wiring remediation in Great Falls?

Yes. Aluminum wiring remediation is one of our specialties for multi-unit buildings, condos, and single-family homes built in the late 1960s and 1970s throughout Great Falls and the broader DMV. We rewire to copper, replace outdated panels, and document everything for insurance carriers.

Generator Installation in Great Falls, VA - Pirro Electric

Homeowners and property managers across Great Falls, Virginia rely on Pirro Electric for generator install. Great Falls is a low-density area of large estate homes on multi-acre lots - meaning long underground service runs, deep gravel driveways for EV charger trenching, well/septic pump circuits, and frequent storm-driven outages that justify whole-home generators.

From Riverbend, Brooks Farm, Falcon Ridge, and Riva Ridge, our licensed electricians deliver the same permitted, code-compliant work that has kept us in business across the DMV since 2003. Standby generators, portable inlet boxes, and automatic transfer switches - installed and inspected.
