Pirro Electric brings 23 years of Virginia electrical experience to every generator install job in Fairfax. Fairfax County's huge stock of 1970s–80s single-family homes and townhomes carries a lot of aluminum branch wiring, original Federal Pacific panels, and 100-amp services that are now overloaded by EVs and HVAC upgrades. Commercial corridors along Route 50 and Route 29 need steady tenant fit-out work.
On any given month you'll find our trucks handling generator installs across Centreville (adjacent), Oakton, Vienna (adjacent), and Annandale (adjacent). We pull permits in Fairfax, schedule inspections, and walk you through the work so nothing gets left to guess.
