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 McLean, VA?

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

Do you handle aluminum wiring remediation in McLean?

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 McLean and the broader DMV. We rewire to copper, replace outdated panels, and document everything for insurance carriers.
