Overview
What We Do
H&H Diesel Services is a full-service heavy-duty diesel repair shop located at 7310 IH 10 West in Seguin, TX. All fleet services — including engine repair, transmission service, electrical diagnostics, preventive maintenance, and DOT inspections — are performed in-house at our facility by our certified technicians. Fleet accounts receive priority scheduling, volume-based pricing, and a dedicated service manager who knows your equipment and keeps your trucks moving with minimal turnaround time.
Priority Scheduling
Fleet accounts get priority access to our bays. When your truck goes down, we get it in fast — because every day it sits is money out of your pocket.
Volume Pricing
Fleet accounts receive volume-based pricing on parts and labor. The more trucks you run with us, the better the rate. We're transparent about pricing — no surprises on the invoice.
Dedicated Service Manager
You get one point of contact who knows your fleet, your equipment specs, and your preferences. No explaining your situation to a different person every time you call.
Consolidated Invoicing
All work across your fleet is tracked and invoiced on a schedule that works for your accounting department. Net-30 terms available for qualified fleet accounts.
Maintenance Records
We maintain complete service records for every unit in your fleet. When it's time to sell a truck or prove compliance, your records are organized and ready.
Mixed Fleet Capability
We service all major diesel platforms — Cummins, Detroit, CAT, Paccar, MaxxForce, Hino, Isuzu, and more. One shop for your entire fleet, regardless of make or model.
