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 Columbia, MD?

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

Do you handle aluminum wiring remediation in Columbia?

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 We rewire to copper, replace outdated panels, and document everything for insurance carriers.

Generator Installation in Columbia, MD - Pirro Electric

Pirro Electric brings 23 years of Maryland electrical experience to every generator install job in Columbia. Columbia's village-by-village development from the late 1960s through the 1990s means many original homes have aluminum branch wiring, Federal Pacific or Zinsco panels, and undersized services. The Town Center redevelopment has driven a lot of recent commercial fit-out work.
