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
  • Scheduled PM service for Central Texas across Austin and surrounding areas
  • Flexible PM days for multi-unit fleets

Central Texas Fleet Maintenance FAQs: What Local Fleets Need to Know

What types of fleet vehicles do you service across Texas?

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 Texas, including the Austin Metro, the Killeen-Temple area, the Waco area, and the Brazos Valley toward Cameron, Giddings, and College Station.

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

Yes. We bring full onsite and mobile repair service just about anywhere in the Austin, TX region — 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 Texas?

We cover Central Texas across four areas: 

  • Austin Metro — Austin, Round Rock, Georgetown, Pflugerville, and Kyle
  • Killeen-Temple area
  • Waco area
  • Brazos Valley / eastern corridor — Burnet, Lometa, McDade, Bastrop, Cameron, Rosebud, Giddings, College Station, and Lexington 
We also support fleets operating along I-35, US-190, US-84, and SH-21, connecting our teams from Waco in the north down through Killeen-Temple and Austin, and out to College Station and the Brazos Valley to the east.

What repairs can you handle onsite in Texas?

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 Texas?

Most Texas 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 Texas 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 Texas 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 Texas?

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 Texas?

Yes. We offer full annual DOT inspections at your yard or facility anywhere across our Central Texas service areas — the Austin Metro, the Killeen-Temple area, the Waco area, and the Brazos Valley toward Cameron, Giddings, and College Station.

What industries do you support around Texas?

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 Texas?

We stock common parts on our service trucks and source others same-day or next-day from local Texas 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 Texas providers?

We show up when we say we will, diagnose issues accurately, and repair trucks right the first time. Texas 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 Texas’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.
