Claim This BusinessAbout W J O'Neil Co
W J O'Neil Co has operated from Livonia, MI for over 40 years, earning a 3.20-star average across 45 customer reviews. As a mechanical contractor, the firm handles commercial and institutional projects across southeastern Michigan, including Ann Arbor and Detroit. Their project portfolio spans education, healthcare, and hospitality sectors, with completed work at the University of Michigan and the DMC Cooling Tower in Detroit. Homeowners reviewing this company should note that the 45-review sample provides a modest signal and that individual project experiences will vary.
Recent website updates highlight new fabrication capabilities. A spool welding robot is now operational and the company opened a dedicated Sheet Metal fabrication shop, expanding in-house production capacity. The site lists three featured projects: student housing at U-M South 5th in Ann Arbor, the Rock City Waterfall Lookout Mountain attraction in Georgia, and a DMC Cooling Tower project in Detroit. These examples suggest focus on commercial and institutional scale work rather than routine residential service calls, which homeowners should consider when evaluating fit for their needs.
Every one-star review posted for W J O'Neil Co since October 2024 cites the same issue: a company vehicle behaving dangerously on public roads. Reviewers report tailgating, swerving across lanes without signals, and drivers using cell phones while behind the wheel. Multiple reports originate from different roadways including Telegraph Road, M-53, and West Jefferson Avenue in Trenton. No reviewer mentioned a specific technician by name, and none discussed the quality of actual HVAC or mechanical service received. This suggests the complaints reflect driver conduct rather than service competence, but buyers should raise expectations around professional driving behavior when booking work.
What Customers Say
All six available reviews award one star, and every complaint describes a W J O'Neil vehicle driving aggressively on public roads. No reviewer criticizes actual installation or repair quality. The pattern suggests the rating reflects employee conduct behind the wheel rather than technical performance.
