The manual on your truck
covers three units.
You service twelve.

Thermo King and Carrier alarm codes, refrigerant charge specs by unit model, and truck engine diagnostics — written by a transport refrigeration technician, not scraped off a forum. Plus the scheduling, quoting and invoicing to run the business around it.

Month to month, no annual agreement. Or call (743) 216-7142 and a technician picks up.

The problem with HD software

Everyone sells you
a filing cabinet.

Work orders, invoicing, inventory. All of it useful, none of it any help when you're standing in front of a unit at 11pm with a load going warm and a code you've never seen.

The alarm code isn't in the book

The manual on the truck covers three units. You've got twelve on your route and half of them are older than the manual.

Ask it in plain language

Thermo King and Carrier alarm codes with the diagnostic path, not just a definition. Type the code and the unit model, get the actual walk-down.

A wrong voltage spec gets somebody hurt

Generic AI tools will confidently tell you a Precedent evaporator motor is 12VDC. It isn't. It's 400–480VAC three phase.

Every electrical result states AC or DC

And separates motor supply from control circuit. That guardrail exists because on a reefer, getting it wrong is the difference in somebody coming home at the end of the day or possibly not.

Charge specs live in five places

One number on a decal, another in a PDF, a third in somebody's memory.

Refrigerant charge specs by unit model

Looked up against the specific unit you're standing in front of, not the family it belongs to.

Parts lookup hands you the whole catalog

Four hundred results, none of them filtered to what you're actually working on.

Filtered to your unit model

With cross-references, so when the first number's on backorder you're not starting over.

The invoice sits unpaid for sixty days

And you've got no mechanism to do anything about it except call and feel awkward.

Automatic late fees

Applied on your terms, without you having to be the bad guy. Fullbay doesn't have this.

Why trust the content

Written by somebody
who'd eat the comeback.

Seventeen years as a transport refrigeration technician before a line of this was written. Every verified entry is in a working tech's own words, not scraped from a forum thread.

How it behaves

Held to a verified standard

  • Every code is checked against a verified entry before it returns
  • Electrical results held to an explicit AC/DC and supply-vs-control standard
  • Procedure-aware safety warnings attach to results that need them
  • Diagnostics cache, so the same code on the same unit answers instantly next time

Just doing reefer work? Reefer Standalone at $79/mo skips the shop management entirely. Managing a fleet rather than fixing one? Fleet Pro is $299/mo, and Fleet Pro Plus white-labels it under your own name. Foreman AI call answering adds to any plan at $59/mo.

Straight answers

Before you sign up.

Which reefer units are covered?
Thermo King and Carrier, including Carrier APX controllers. Alarm codes come with the diagnostic path rather than just a definition. Coverage keeps growing, and HD Elite subscribers get new content first.
How do I know a spec is right?
Verified entries are written by a transport refrigeration technician with seventeen years on these units. Every entry is checked by a working technician before it goes in. On electrical results the system is required to state AC or DC and separate motor supply from control circuit voltage — that rule exists because on a 480V three-phase circuit it's the difference in somebody coming home at the end of the day or possibly not.
Can I run light duty work on the same account?
Yes. The light duty side covers cars, pickups and vans. If you do both, the HD + LD Elite Bundle at $199/mo gets you everything in one subscription.
Does it work on a phone in a lot at night?
That's the design target. One hand, cracked screen, bad light. Results cache, so a repeat code on a repeat unit comes back instantly even on a weak signal.
What about fleets rather than a service truck?
Fleet Pro handles fleet and shop management together, and it's shipping now at $299/mo. A driver scans a QR code entering a truck, pre-trip and post-trip forms attach, and a problem report generates a work order pre-filled with VIN, serial, mileage and unit details. Fleet Pro Plus white-labels the whole thing under your own name so you can offer it to your fleets as your product — that one's set up per partner, so call us.
Other side of the shop

Also turn wrenches on light duty?

Built by a reefer tech. That's the whole pitch.
