Air System FAQ

Can I drive with an air leak?

If the low-air warning comes on, stop in a safe place. Air brakes depend on system pressure. Call us with your location and what you are seeing or hearing.

Can an air compressor be replaced on the roadside?

Often, yes, depending on the truck and parts availability. The dispatcher will tell you before dispatch if a shop is the better option.

How fast can you get to me?

It depends on your location, the time of day and which technicians are available. Before anything is dispatched, we give you a confirmed ETA from the technician who is actually coming.

Do you take fleet cards / company billing?

Yes, fleet cards are accepted. Companies that use us regularly can ask about a fleet account for company billing.
