About Jay’s Diesel Repair LLC
Jay's Diesel Repair LLC operates in Columbia, South Carolina, specializing exclusively in diesel engine repair services. The business maintains a 3.9-star rating gathered from seven customer reviews, offering round-the-clock availability seven days per week. Technicians respond to service calls across the Columbia metropolitan area, assisting owners of diesel-powered vehicles and equipment requiring mechanical attention.
Without a functional website, specific brand partnerships or specialized certifications remain undocumented, limiting comparison against regional diesel service competitors. The business operates with stated 24-hour availability, though customer reviews present conflicting accounts regarding response consistency.
Customer feedback references Jay by name, with one reviewer detailing anemergency service callduring which the technician arrived despite being over 40 minutes away, carrying a required part and completing repairs on a truck loaded with 21 tons of cargo. Another reviewer describes the team making a house call to diagnose an issue that enabled safe travel to Minnesota. However, separate reviews accuse the business of failing to arrive during scheduled windows and inflating invoices through unnecessary charges.
What Customers Say
Three reviewers specifically praise service speed and honesty, while two others describe no-shows and billing disputes. Positive reviews highlight same-day emergency response and diagnostic accuracy, while negative reviews cite broken promises about arrival times and undisclosed charges adding to final invoices.
