| EV charger installation | Yes | Adding a dedicated 240V circuit for a Level 2 home electric-vehicle charger. |

About Our Bethesda Services
Bethesda, Maryland represents the pinnacle of suburban sophistication, where tree-lined streets, exceptional schools, and proximity to Washington DC attract families and professionals who appreciate quality in every aspect of their homes. AJ Long Electrical has served Bethesda homeowners for decades, developing specialized expertise in the high-end residential electrical systems these discerning clients require.
Bethesda's residential architecture spans generations of American building, from the Sears kit houses of Edgemoor to the stately colonials of Bradley Hills, from the mid-century moderns of Kenwood to the contemporary showcases rising throughout downtown Bethesda. Each neighborhood presents distinct electrical characteristics and challenges our experienced technicians understand thoroughly.
The significant renovation activity throughout Bethesda has made us a trusted partner for architects, designers, and high-end remodeling contractors. These comprehensive projects often involve complete electrical system replacement, sophisticated lighting design, smart home infrastructure, and integration with luxury amenities including home theaters, wine storage, and spa-quality bathrooms. We collaborate from the design phase to ensure electrical systems support the project's vision completely.
Bethesda's older neighborhoods contain homes from the 1920s through 1960s that often retain original electrical systems inadequate for modern life. Panel upgrades from 100-amp to 200-amp or 400-amp service, replacement of ungrounded circuits, and installation of modern arc-fault and ground-fault protection throughout are common requests. We complete these comprehensive updates with minimal disruption to the home's historic character.
The National Institutes of Health, Walter Reed National Military Medical Center, and numerous research institutions make Bethesda home to many medical and scientific professionals. These homeowners often request dedicated home office circuits with hospital-grade isolated grounding, uninterruptible power supplies for sensitive equipment, and comprehensive surge protection for expensive electronics.
Downtown Bethesda's transformation into a true urban center has created demand for electrical services in luxury high-rise buildings. We partner with building management and condominium associations to address common challenges including aging building infrastructure, unit-level upgrades within high-rise constraints, and EV charging installation in parking structures.
Montgomery County maintains rigorous building codes and an active inspection program. Our extensive experience with county permitting ensures your project receives proper approvals and passes inspection without delays. We understand the specific requirements Montgomery County inspectors apply and prepare every project accordingly.
