Open 24/7, including holidays
A&S Mobile Mechanic Services brings the shop to you. Anthony works out of a service truck that carries most parts, so most repairs happen right where you broke down: the shoulder of the highway, a job site, a fleet yard or your driveway. Semi trucks, trailers, cars, pickups and vans. Day or night, holidays included. You get a rough estimate before work starts, and you only pay for the repairs you need. If a part isn't on the truck, he can usually track it down any hour of the day.
Payment options
Phone is required so we can call you back fast.
Semis, trailers & heavy duty
Certified on Freightliner and Caterpillar, with the tools to find the problem and fix it at the truck.

Computer diagnostics to find the real problem first. Then major engine work, transmission, turbo and DEF system repair, done by a certified diesel mechanic.

Locked your keys in the car? Call and we'll come get it open, day or night.
Fleets & owner-operators
Keep your trucks earning instead of sitting at a shop.
Oil changes and preventive maintenance done at your yard, on your schedule. Brakes, tires and fluids checked while we're there, so drivers aren't pulled off routes.
