The Problem & Our Solution

Technicians deserve better tools.
We built them.

Cold-chain reliability is non-negotiable. Every minute of reefer downtime puts cargo at risk and costs money.

Today's Reality

Hundreds of alarm codes across two major brands — impossible to memorize

Flipping through paper manuals in the field wastes critical repair time

Downtime costs mount every minute a reefer unit isn't diagnosed correctly

Service reports take hours to write up manually after each job

With Reefer Tech Pro

Instant lookup of any Carrier or Thermo King alarm code in seconds

AI Agent provides step-by-step fix guidance right on your iPhone

Diagnose issues faster and get units back online before cargo is compromised

Generate professional PDF service reports with one tap

Testimonials

Trusted by technicians
across the cold chain.

I used to spend 30 minutes hunting through paper manuals for alarm codes. With Reefer Tech Pro, the AI tells me exactly what to check and in what order. It's like having a senior tech on call 24/7.

Our service team's average repair turnaround dropped by over 40% in the first month. The AI troubleshooting is genuinely impressive — it catches things we'd normally miss on first inspection.

The PDF report feature alone is worth the subscription. We used to spend hours writing up service sheets. Now it's done before the technician leaves the site. Game changer for our admin team.

For Fleets

Licensed to your fleet.
Not to your techs.

ReeferTechPro is sold per fleet, not per technician. Your team gets the full diagnostic suite; access stays under your control.

1

Per-fleet licensing

One contract covers your whole team. Add or remove technicians anytime — access follows the fleet, not the individual.

2

Revoke when techs leave

When a technician moves on, you revoke their account in seconds. No risk of them keeping access on a personal device.

3

Custom-priced per seat

Small workshops to multi-depot operations. We quote based on team size and depot count — no public price list.

4

Fleet-wide history

Every job your team has logged, every refrigerant top-up, every alarm seen — all visible to fleet admins.

5

Manuals tuned to your fleet

We can integrate your unit-specific manuals so the AI Agent answers in your fleet’s context, not generic web data.

6

Hands-on onboarding

We set up your team, train your techs, and stay on call. No DIY signup flow — real humans answering email.
