Our PM programs include:

  • Multi-point inspections
  • Engine oil, filters & fluid service
  • Brake, suspension & steering checks
  • DOT compliance checks
  • DPF/after treatment health checks
  • Battery & electrical system testing
  • Tire & tread inspections

Indiana Fleet Maintenance FAQs: What Local Fleets Need to Know

What types of fleet vehicles do you service across Indiana?

We work on Class 3–8 commercial vehicles including delivery vans, service trucks, box trucks, medium-duty units, and semis. We also service dry van, refrigerated (reefer) trailers, flatbeds, and utility trailers throughout Central Indiana, including the Indianapolis Metro area.

Do you provide mobile repairs at our yard, job site, or roadside in Indiana?

Yes. We bring full onsite and mobile repair service just about anywhere in the great Indianapolis area — whether your truck is in a distribution yard, on a job site, or down on the shoulder. Most issues can be diagnosed and repaired without towing.

What areas do you service in across Indiana?

We cover Central Indiana, including Indianapolis and Alexandria, IN, and the surrounding metro. We also support fleets operating along I-65, I-69, I-70, I-74, and I-465, connecting our teams across the greater Indianapolis area.

What repairs can you handle onsite in Indiana?

Most day-to-day fleet repairs can be handled onsite, including:

  • Diagnostics & check-engine troubleshooting
  • DPF/DEF/emissions system work and forced regens
  • Electrical, batteries, starters, alternators
  • Brake, wheel-end, and air system repairs
  • PM services & fluid/filter changes
  • Trailer brakes, lighting, wiring, suspensions

If it’s safe to repair onsite, we’ll handle it right where the truck sits.

How fast can you respond to breakdowns in Indiana?

Most Indiana fleets are seen same day, and emergency calls are prioritized based on technician availability. We communicate clearly with accurate ETA updates so you know when help is on the way.

Do you offer scheduled PMs for Indiana fleets?

Yes. We build preventive maintenance programs around your routes, mileage, and OEM intervals. We can service multiple units in one visit and help you stay ahead of breakdowns.

Can you service several trucks during one visit?

Definitely. Many Indiana fleets schedule batch PMs or hand us a repair list when we’re onsite. This keeps downtime low and prevents trucks from coming off the route during business hours.

Do you offer after-hours or weekend service in Indiana?

Yes — after-hours and weekend appointments are available for fleets that prefer off-shift maintenance to keep trucks rolling during the day.

What diagnostic tools do you use?

We run modern diagnostic platforms like AUTEL, JPRO and OEM-level software so we can accurately troubleshoot check-engine lights, emissions issues, electrical faults, and regen problems onsite.

Can you perform DOT inspections onsite in Indiana?

Yes. We offer full annual DOT inspections at your yard or facility anywhere across our Central Indiana service areas.

What industries do you support around Indiana?

Construction, roofing, last-mile delivery, HVAC/plumbing, landscaping, manufacturing logistics, municipal fleets, and service contractors. If your business depends on reliable trucks, we support it.

What payment options do you offer? Can we set up fleet billing?

We offer standard payment options plus fleet billing for qualified accounts. Weekly or per-visit invoicing is available depending on what fits your operation.

How fast can you get parts in Indiana?

We stock common parts on our service trucks and source others same-day or next-day from local Indiana suppliers across our service regions. Our goal is to avoid long waits and get trucks back in service fast.

What makes your mobile service different from other Indiana providers?

We show up when we say we will, diagnose issues accurately, and repair trucks right the first time. Indiana fleets use us because we operate like a partner — focused on uptime, communication, and preventing repeat problems.

Ready to Take the Shop Out of the Shop Visit?

We’re more than a mobile mechanic — we’re Indiana’s fleet partner focused on uptime, compliance, and cost control. Our mobile service eliminates unnecessary downtime. Our onsite programs keep operations efficient and on schedule.
