Service Area
H&H Diesel Services provides professional heavy-duty diesel repair for commercial truck operators and fleets running routes to and from Corpus Christi, TX. Our full-service shop in Seguin is accessible via US-37 and IH 10.
What We Offer
When a heavy-duty truck or commercial fleet vehicle goes down in the industrial corridors surrounding Corpus Christi, our mobile diesel technicians deliver on-site heavy-line repair wherever your driver is stranded. We stage our units across the Port of Corpus Christi, Refinery Row, and the Navigation Blvd / Leopard Street freight routes to keep semis, hotshot rigs, and port-bound carriers moving. Whether your truck derates near the Citgo and Valero complexes, loses power along I-37, or shuts down in the distribution zones around Hwy 44 and Robstown, our team arrives equipped with OEM-level diagnostics and the tools needed to get your equipment operational again.
Corpus Christi's mix of refinery traffic, port logistics, and coastal construction work also puts heavy strain on vocational trucks operating through Calallen, Annaville, Flour Bluff, and the jobsite networks feeding Nueces and San Patricio counties. Our heavy-line specialists understand the cooling, suspension, brake, and engine issues common to water haulers, dump trucks, cement mixers, and equipment haulers working long hours in high-heat, high-humidity environments. From freight carriers running oversized loads toward Ingleside and Portland to local operators hauling materials along SPID or the Southside commercial corridor, our company stands as Corpus Christi's most dependable partner for minimizing downtime and keeping heavy equipment productive.
Our certified technicians use OEM-level diagnostic software and professional-grade equipment to accurately diagnose and repair heavy-duty diesel trucks and equipment. We work on all major platforms including Cummins, Detroit Diesel, CAT, PACCAR, Volvo, and International.
