Most small fleets in this city are maintained by whoever is closest to the yard on the day something goes wrong. That works until two trucks are down in the same week and nobody can say when either of them last had brakes measured.

Floorjack Auto Repair is at 21242 N. Black Canyon Hwy, Suite D, on the frontage road along I-17 at Happy Valley Road. Work trucks and vans are ordinary traffic here, gas and diesel both, and the shop is set up so a fleet vehicle can be handed over outside the hours a crew is actually working.

What a Phoenix work week does to a fleet

A work vehicle in this city does the worst version of almost every duty cycle. Mornings are cold starts and short hops between job sites. Middays are long idles with the AC at full and the engine making no airflow of its own. Afternoons are stop-and-go on Bell, Thunderbird or Camelback, then a freeway run that ends before anything has settled.

That pattern is hard on specific parts, and it is the same parts every time. Brakes go early because the miles are urban and loaded. Batteries die in their third summer instead of their fifth, because heat kills a battery faster than cold does and this city delivers five months of it. Cooling systems and AC compressors run at their limit on a truck that is idling rather than moving. Tires wear unevenly on vehicles that carry weight in the back and nothing in the front.

Dust does the rest. Fine desert grit loads an air filter, packs the face of a radiator and gets into brake hardware in a way it does not in a milder climate. None of it announces itself. It shows up as a truck that will not start on a Tuesday morning with a full day booked.

Fleet work we handle in Phoenix

  • Scheduled maintenance on a per-vehicle interval, set from what the truck actually does rather than from a sticker
  • Brakes, steering, suspension and wheel bearings on loaded vehicles, which wear faster than the manual assumes
  • Cooling systems and AC, tested ahead of the summer instead of during it
  • Batteries, alternators and charging faults, which is where most no-start calls end
  • Tires, rotation and alignment on vehicles that carry weight unevenly
  • Engine diagnostics and check engine light work on gas and diesel
  • Diesel service on the one-tons, including injectors, turbos and emissions hardware

The ceiling is a 3500 chassis, and we do not take semis, trailers or boats. What the program covers across the metro, and how an interval gets set, is on our fleet maintenance page.

Getting a truck in without losing the day

The shop is on the frontage road, not behind three signals off it. Northbound or southbound on I-17, a truck exits at Happy Valley and is here. For a fleet running the north side of the city, that is the difference between a drop-off that costs twenty minutes and one that costs a morning.

Hours are Monday to Friday, 8am to 5pm, which is the same workday your crews have, so most fleet vehicles arrive outside them. Text or call the shop first, wait until you have heard back, then leave the truck and post the key through the slot at the back of the building. The vehicle is already here when the shop opens, and Javen calls before anything is touched.

Fleet accounts also get priority booking, which is the part that matters once you are running more than a couple of vehicles. An account truck gets scheduled ahead of the general queue, so the interval you set is one you can actually hold to.

Approval before the wrench

Every vehicle gets diagnosed, then you get a price, then you decide. Nothing goes on an invoice that was not approved first, and the number does not move after you have approved it. On a fleet that matters more than it does on a single car, because a surprise across six trucks is not a surprise, it is a budget problem.

Fleet accounts are invoiced to the business on net 30 and paid by check, so a repair does not stall waiting on somebody with the company card, and account pricing on parts and labor is below the counter rate.

If the timing is bad, American First Finance splits the bill into payments and does not require perfect credit.

Common questions

Answers before you bring it in

We don’t keep the phone around for fun. Call us; we’re glad to help.

Call Us
Do I have to bring every truck in on the same day?

No, and it is usually a bad idea. Putting a whole fleet in the shop in one week means the whole fleet is down in one week. We stagger the intervals so vehicles come through a few at a time, which spreads the cost and keeps the crews working. If your season has a slow stretch, tell us when it is and we will weight the schedule toward it.

My drivers work the same hours you are open. How does a truck get here?

Most of them arrive after five. Text or ring the shop before the driver heads over, give us the vehicle and what it is doing, and wait to hear back. Then the truck gets left and the key goes through the slot at the back of the building, the door marked Sweet D. It is already here when we open, so the morning does not wait on somebody driving up the 17 at eight.

Do you keep a record of what each vehicle has had done?

Yes. Repairs are filed against the VIN, so any one vehicle can be pulled out of the system on its own and printed as a full history of what it has had done here. It is the thing fleets usually cannot produce. When a van gets sold, or a driver is sure the brakes were done in the spring, there is a record to look at.

Are my vehicles going to pass emissions?

We do not run the test. Maricopa County testing happens at a state station, so no certificate comes from us. What we handle is the diagnosis and the repair, which is where the actual work is: an EGR valve, an oxygen or NOx sensor, an evap fault, or the DPF and DEF hardware on a diesel. If a truck is due for registration and the check engine light is on, bring it in before the test. A lit light fails automatically, and the retest costs you a second trip.

Is it worth driving trucks up here if my yard is on the other side of town?

That depends on where the trucks already go. If your routes touch the 17, the 101 or the north side of the city at any point in a day, a drop here costs a detour rather than a trip. If your yard is in the southeast Valley and nothing you run comes north, it probably is not worth it, and we will tell you that on the phone rather than after you have driven up. What you get for the drive is one shop holding the history on every vehicle, diesel work done in house instead of sent to a dealer, and a key drop that covers the hours your crews are actually working.
