    Panel Upgrades & Heavy-Ups in Potomac, MD - Pirro Electric

    Pirro Electric brings 23 years of Maryland electrical experience to every panel upgrades job in Potomac. Potomac is dominated by large single-family estates with high electrical demands: indoor pools, geothermal and dual-zone HVAC, exterior lighting on long driveways, and increasing demand for multi-vehicle EV charging. Many of the 1960s and 1970s houses off Falls Road and River Road in Bradley Farms, Falconhurst and Glen Hills are still on their original 100- or 150-amp services with subpanels added piecemeal over the decades, so a single addition or pool heater can push the whole house past capacity. Lots here are also deep and heavily wooded, which means long underground runs to gates, guest houses, barns and detached garages, plus outages from tree limbs on the overhead laterals near the C&O Canal and Cabin John Regional Park.

    On any given month you'll find our trucks handling 400-amp service upgrades across River Falls, Bradley Farms, Falconhurst, and Glen Hills. We pull permits in Potomac, schedule inspections, and walk you through the work so nothing gets left to guess.
