For commercial HVAC service companies

Know before
it breaks.

Clip a battery-powered sensing device onto every unit you service, during a visit you were already making. When one starts to fail, you know days early, so a panic call becomes a planned visit.

The problem

Right now, a unit you service is failing. You'll find out when the phone rings.

A unit failing isn't the problem. Fixing units is what you do. The problem is the surprise. Every breakdown they didn't see coming costs you a little trust, and trust is what keeps the contract, earns the referral, and sells the next system. That's worth far more than any single repair.

Every one of those failures had a signature in the data first. There was just no data. That's the whole problem this fixes.

Hottest day of the year. A unit you service quits, the store starts losing business, and now it's an emergency on the busiest day of your year.

Every fix becomes an emergency: the 2am callout, the truck rolled to a unit that was fine, the one across town you didn't even know was down.

Dozens of units across every site. None of them tell you which one's dying.

If it has a refrigerant line, it can be read. Clip-on probes never open the circuit and never touch the unit's electronics, so brand and age don't matter.

Solution · how it works
It tells you first

Clip it on.
We do the watching.

Nine measurement points across the refrigerant and air cycles, watched around the clock, flagging the fault before it takes the unit down.

01

Clip it on

Clip-on temperature probes and current clamps, fitted during a normal visit. Never opens the refrigerant circuit: no gauges, no lost refrigerant, no mains wiring, no electrician.

02

Set up from a phone

Guided setup over Bluetooth, minutes per unit. Battery powered with cellular built in, so nothing gets wired and nothing touches the site's network.

03

You hear it first

A plain alert with the measurements behind it, straight into dispatch. The tech arrives knowing the likely fault, with the right parts on the truck.

What it catches

Eight faults, caught while they're still cheap.

Superheat is computed on the device from the measured temperatures, and every reading is checked against the fault signatures that take units down. Every alert carries the evidence behind it.

Alerts become scheduled work. They surface in the tools your dispatchers already run, with CMMS, ERP or ServiceTitan integration scoped per deployment. And the platform underneath is Blynk's, already serving HVAC fleets today.

The payoff

The call you get to make.

The one you almost never get to make, before anything's broken:

“Morning. Just so you know, your unit on Building C is heading for a failure. I've got you booked in for Thursday.”

You're still the company they call when something breaks. The difference is now you call them first, before it does. That call is worth more than the repair. It's why they keep you.

And you're not asking them to take your word for it. You show them the same chart you saw the failure coming on, so the bill stops being a surprise and “did you actually fix it” stops being an argument.

The record

When they call it a callback, you've got the proof.

Every unit keeps its own history. So when a manager says you were just there and it's broken again, you can show the unit you serviced has run clean ever since, or that it's a different unit that's now drifting. You stop eating callbacks that were never yours. And when a fix doesn't hold, you see it within hours and go back on your own schedule, before it turns into an angry comeback.

The board

Your whole book, triaged.

Every unit you service, sorted by what needs a look this week. Plain language instead of sensor codes, and a running count of what you caught before it broke.

What changes

Four things stop costing you.

/01

Emergencies become appointments

Same-day scrambles turn into planned visits.

/02

Techs roll knowing

They arrive with the likely fault, not a guess.

/03

Contracts stop bleeding

No more fixed-fee jobs eaten by emergency labour.

/04

You move up-market

Sell predictive as a tier nobody else offers.

Stop competing on who shows up fastest.
Start being the one who saw it coming.

The growth math

More contracts. Same techs.

You can't hire your way to growth right now: your technicians' weeks are effectively sold out, and 20–40% of them go to scheduled visits that happen because the calendar says so. Monitoring flips that. Visits happen when the data says something is drifting, the agreement and the price stay, and the freed hours go into the work you're turning away today.

Recurring revenue

A tier your competitors can't quote.

You already sell maintenance contracts. This adds a rung on top of them: the same agreement, plus eyes on every unit between visits. New recurring revenue on the customers you already have, with no new business model to learn.

Why us

Built for the way you actually work.

Everyone else sells your customers a dashboard to ignore. This one they never see. It's built for the only people who act on it: your crew.

Any unit, any brand

It reads temperatures, so the manufacturer doesn't matter.

Nothing to integrate

No BAS, no controls, no IT project. It clips on.

Old units welcome

The aging equipment you babysit is exactly what it watches.

See the whole roof

Every unit, every site, which one needs you today.

Built on Blynk, the platform behind live HVAC fleets. Reads the sensors you already have, on any brand of unit. Tuned for real faults, not nuisance alarms. Your data stays yours, exportable, no lock-in. Validated on real rooftop-unit fault data.
