The furnace was saying what was wrong. Nobody was listening.
FurnaceWatch started with a furnace that kept failing. A dirty flame sensor one winter, a draft inducer the next. Each time, the technician diagnosed the problem in minutes and said the same thing: it had been acting up for a while.
The information existed — in the sound of the inducer, the rhythm of the cycles, the heat call that went unanswered. It just wasn't reaching anyone. So our founder, an engineer, instrumented his own furnace and started listening.
What became clear along the way is who actually needs that signal. Not the homeowner — they find out when the house gets cold either way. It's the service company that installed the furnace, warranted it, and put its name on the maintenance agreement. They take the 6 AM call, roll the truck without a diagnosis, and eat the callback. They should know first, and they should know what.
That's what FurnaceWatch is: a sensor your technician mounts on the furnace, and a portal that tells your office the failure mode the moment a heating cycle goes wrong. It doesn't predict the future and it doesn't replace your technicians — it hands them the diagnosis before the truck leaves.
FurnaceWatch is founder-led and early. If you book a demo, you'll be talking to the person who designed the hardware, trained the detection, and built the portal — and who wants to hear exactly where it falls short for the way your company runs.
Diagnosis, not prediction
We tell you what failed the moment it fails. We don’t claim to see the future, and we won’t sell you copy that does.
Open evidence
Every alert carries the cycle behind it — what the sensor saw and when. No black boxes.
Built for technicians
The install has to fit inside a normal maintenance visit, or it doesn’t ship.
On the device
Detection runs on the sensor itself, so a Wi-Fi drop never means an unwatched furnace.
