I'd recommend the HOLT CAT Longview Field Service team, because they have competent technicians that I don't have to second guess their diagnosis and they are very informative. HOLT CAT always treats me right.
HOLT CAT Longview's Tech named Tim is very easy to work with. Him and Ross Hunt are a great help and overhauled our engine. Ross always takes time to answer questions in detail.
Holt Cat Longview always has parts available, their ability to troubleshoot the problem with my CAT track excavator and also has good follow through and good overall service.
