What American Electrical Testing Co., Inc. does

American Electrical Testing Co., Inc., operating as Asplundh Electrical Testing, LLC (AET), is a U.S. independent electrical testing firm founded in 1980 and headquartered in Foxboro, Massachusetts. The company has been a wholly-owned subsidiary of Asplundh Tree Expert, LLC since 2009 and operates as part of the broader Asplundh Family of Companies. AET provides four integrated service lines: electrical maintenance testing, acceptance testing, commissioning, and transformer services, supplemented by 24/7 emergency support. All field work is delivered by NETA-certified technicians using NIST-calibrated test equipment, with the company holding InterNational Electrical Testing Association (NETA) accreditation, recognized by ANSI as a standards-making body.

The company sells professional services on a quote-based, project-by-project basis to enterprise and government customers, with multi-year contracts typical. It serves at least eleven vertical segments, including electric utilities, power generation, hospitals, industrial/commercial facilities, municipalities/co-ops, pharmaceutical plants, electrical contractors and engineers, transportation infrastructure, government facilities, and data/telecommunications centers. Field sales representatives manage direct enterprise relationships, and a network of regional offices supports nationwide service delivery across the United States.

AET's go-to-market leverages the One Asplundh integrated approach, which bundles electrical testing with parent-affiliate offerings in vegetation management, storm response, and digital innovation, allowing cross-sell into utility customers. Marketing channels are primarily the corporate website, direct customer relationships, referrals, and limited community sponsorships (e.g., Philadelphia Phillies Community Partner). No public revenue, funding, or AI/ML capability disclosures are present in the input data.
