Bridging Research and Reality

At Wattnest, we bring research-grade HVAC fault detection and predictive maintenance from the lab to commercial HVAC service companies. Our mission is to make every service truck smarter, every technician faster, and every building safer.

The Challenge We're Solving

Commercial HVAC systems are the backbone of building operations, yet the industry still relies on reactive maintenance that costs more, wastes energy, and disrupts tenants.

HVAC systems account for 40% of commercial building energy use, making efficiency critical
85% of HVAC equipment failures are preventable with early detection
Reactive maintenance costs 3 to 9 times more than predictive maintenance
Unplanned HVAC downtime costs $2,000 to $10,000+ per hour for data centers
Current monitoring relies on manual inspections and scheduled maintenance that misses developing faults
