The idea for FurnaceWatch started with a frustration that millions of homeowners know all too well: the furnace stops working in the middle of winter, and the repair is never a surprise to anyone except the people living in the house.
Our founder experienced this firsthand -- repeatedly. A clogged filter here, a failed flame sensor rod there, a draft inducer motor that was showing signs for months before it finally quit. Each time, a service technician would come out, diagnose the problem in minutes, and explain that the warning signs had been building for weeks. The fix was often simple. The cost -- the service call fee, the missed workday, the scramble to be home during a four-hour window -- was anything but.
What made it worse was that the same failures kept happening. Not just in one house -- in homes across every neighborhood. Dirty flame sensors. Worn inducer bearings. Failing limit switches. The HVAC industry has known about these failure patterns for decades. Yet homeowners were still paying emergency rates for problems that were entirely predictable.
Even with a manufacturer warranty, the hassle did not go away. Scheduling a technician, arranging to be home, waiting for parts -- the administrative burden was often as costly as the repair itself. And when the same component failed again two seasons later, there was no history, no trend, no warning. Just another call, another bill, another disruption.
FurnaceWatch was built to change that. By monitoring the mechanical health of a furnace continuously, the platform catches the early signs of failure before they become emergencies. Technicians know what is wrong before they walk in the door. Homeowners get a heads-up, not a breakdown. Service companies can schedule preventive visits instead of chasing emergency calls at midnight.
This is not about replacing HVAC professionals -- it is about giving them the information they need to do their best work. And giving homeowners the peace of mind that comes from knowing their furnace is watched, not just hoped for.
How we build.
Edge-First
Intelligence runs on the device, not in the cloud. Our model infers locally so alerts are fast, reliable, and private.
Honest Uncertainty
We report probability scores, not binary verdicts. A 94% confidence level is useful. False certainty is dangerous.
Built for Technicians
We interview HVAC techs constantly. Features exist because real people needed them — not because a PM wrote a spec.
Open Diagnostics
Every alert includes the vibration data and model evidence behind it. No black boxes.
Minimal Footprint
One sensor. One outlet. 15-minute install. We respect the technician's time.
Long-Term Reliability
Designed for 5+ year deployment in harsh environments. Industrial-grade components throughout.
The people behind it.
