The Problem

The old way is costing you

Every one of these problems is bleeding your margin — and you might not even see it happening.

Wasted callouts

Techs head out with no idea what's wrong. 40% of first visits are just diagnosis — the actual fix needs a second callout with parts.

Reactive, not proactive

You only find out a unit is failing when the tenant calls to complain. By then it's an emergency — and your reputation takes the hit.

No visibility across your fleet

Dispatchers juggle spreadsheets, phone calls, and guesswork to figure out which units need attention first.

Wasted energy, angry clients

Underperforming units run up power bills for months before anyone notices. By the time you hear about it, the client is already shopping around.

The Solution

There's a better way

Cold Pulse gives you eyes on every unit, AI that diagnoses faults before they become emergencies, and the tools to fix problems remotely.

Fleet Overview

Real-time IoT monitoring across every unit

Every unit reports suction and discharge pressure, superheat, subcooling, delta-T, compressor amps, fan amps, and filter dP every 30 seconds. You see it all on one dashboard — no more guesswork.

Fault Detection

AI catches faults before the client calls

12 built-in fault rules detect low charge, dirty filters, compressor overcurrent, fan failure, high head pressure, freeze-up, short cycling, and more. Alerts fire instantly with severity levels so you can prioritize.

AI Diagnostics

Full diagnostic reports, written by AI

When a fault is detected, AI generates a complete diagnostic report: root cause analysis with confidence scores, alternative diagnoses, step-by-step technician instructions, parts needed, and energy cost impact. Your techs arrive prepared.

Remote Control

Fix issues without sending a tech

Some problems don't need a visit. Restart systems, reset timers, or reboot devices remotely. View live telemetry charts with pressure, temperature, and electrical data to verify the fix worked.

Features

Everything you need to run smarter

One platform for monitoring, diagnostics, and dispatch — built for commercial aircon.

Real-Time Sensor Data

Pressure, temperature, amps, and filter dP — every 30 seconds from every unit.

AI Fault Detection

12 fault rules catch low charge, overcurrent, freeze-up, short cycling, and more.

Diagnostic Reports

AI-generated root cause analysis, confidence scores, parts lists, and repair steps.

Remote Commands

Restart, reset, or reboot units remotely. Verify the fix without sending a tech.

Multi-Site Dashboard

Monitor every unit across every site from one place. Filter by location, status, or severity.

Automated Alerts

Instant notifications when faults are detected. Prioritised by severity so you act on what matters.

Technician Instructions

Step-by-step repair instructions generated by AI, included in every diagnostic report.

Energy Monitoring

Track energy consumption per unit. Spot underperformers before clients see the bill.

simPRO & ServiceM8 Integration

Faults automatically create jobs in your existing system. No double-entry.

Integrations

Plugs straight into your job management

Cold Pulse integrates with simPRO and ServiceM8 so faults go directly into your workflow — no copy-pasting, no phone calls.

simPRO

Job management integration

When a fault is detected, Cold Pulse automatically creates a job in simPRO and assigns it to the closest available technician. The job includes the expected issue, AI diagnostic notes, parts likely needed, and step-by-step repair instructions — so your tech arrives ready to fix, not diagnose.

ServiceM8

Field service integration

Faults flow directly into ServiceM8 as new jobs, routed to the nearest tech based on location. Each job is pre-loaded with the AI-generated diagnosis, confidence scores, and recommended actions — turning a reactive callout into a planned, first-time fix.

How It Works

Up and running in minutes

Three simple steps from install to intelligent monitoring.

Install

We ship a ready-to-install sensor kit with pressure transducers, temperature probes, and CT clamps. Most units take 10–15 minutes. No special tools, no electrician required.

Monitor

Every 30 seconds, your units report suction pressure, discharge pressure, superheat, subcooling, delta-T, compressor amps, fan amps, and filter differential pressure. All visible in your dashboard.

Diagnose & Fix

When something goes wrong, AI generates a full diagnostic report with root cause, confidence scores, parts needed, and step-by-step instructions. Jobs are created in simPRO or ServiceM8 automatically.

Our Story

Built for aircon businesses, by someone who gets operations

Cold Pulse was built on the Gold Coast by Daine Reid — an operations leader who spent years watching service teams waste time on blind callouts. This is the tool he wished existed.

FAQ

Common questions

What hardware do I need?

We ship a ready-to-install hardware kit with each subscription. It includes an ESP32-based sensor board with pressure transducers, temperature probes, and CT clamps. Works with R410A, R407C, and R22 systems. No special tools or electrician required.

How long does installation take?

Most units take 10–15 minutes. Mount the sensor board, connect the probes, and power it on. The unit appears in your dashboard within seconds. We include a step-by-step install guide and video walkthrough.

What faults can it detect?

Cold Pulse detects low refrigerant charge, dirty or blocked filters, compressor overcurrent, fan motor failure, high head pressure, evaporator freeze-up, short cycling, and abnormal delta-T. That covers the vast majority of common faults in commercial split systems.

Is there a free trial?

Yes — 14-day free trial on your first unit, no credit card required. After that, plans are billed monthly on a 12-month agreement. Cancel any time after the minimum term.

How does AI diagnosis work?

When a fault is detected, our AI analyses the sensor data pattern — comparing current readings against known fault signatures and historical baselines. It generates a diagnostic report with root cause analysis, confidence scores (e.g. 87% likely low charge), alternative diagnoses, recommended parts, and step-by-step repair instructions for your technician.

What if I have older AC units?

Cold Pulse works with most commercial air conditioning systems — split systems, packaged units, VRF systems, and chillers. The sensor kit is designed to retrofit onto existing equipment regardless of age or brand. If you're unsure about compatibility, book a call and we'll check your specific setup.
