Thalo Labs announced an investment from Suffolk Technologies, the venture capital affiliate of Suffolk Construction, along with a strategic partnership to accelerate the adoption of AI-powered HVAC diagnostics and service intelligence. The investment reflects growing demand for more proactive and intelligent service models across the HVAC industry as contractors face labor shortages, aging infrastructure, and increasing system complexity.
The company’s platform combines hardware, advanced sensing, physics-based AI models, and generative AI tools to provide real-time diagnostics for HVAC systems. The technology is designed to help contractors identify issues such as refrigerant leaks, compressor overheating, voltage anomalies, short cycling, and improper operating modes before failures occur. By delivering real-time alerts, root-cause diagnostics, and guided remediation, the platform aims to reduce unnecessary truck rolls, improve service efficiency, and help contractors increase profitability.
According to the company, the HVAC industry is facing a shortage of more than 110,000 technicians across the United States, while many existing systems still lack modern real-time diagnostics. Traditional building management systems have primarily focused on building owners and operators rather than field technicians. Thalo Labs said its platform addresses this gap by delivering technician-level intelligence directly at the equipment layer.
Founded by Dr. Brendan Hermalyn, who previously led the camera program at Waymo and autonomous hardware initiatives at GM Cruise after a science career at NASA, Thalo Labs applies expertise from aerospace, robotics, and autonomous systems to building infrastructure. The company said its Sidekick sensor platform is non-invasive and can be installed during routine maintenance visits in just minutes.
Suffolk Construction is piloting the technology at its headquarters through deployment of Sidekick sensors. The pilot is intended to support the transition from reactive maintenance toward AI-enabled, data-driven building operations.
Suffolk Technologies said the investment aligns with its broader strategy of backing technologies that improve productivity, sustainability, and asset performance across the built environment.
KEY QUOTES:
“HVAC service is one of the most operationally complex businesses in the built environment. Contractors have been running it with tools that haven’t really changed in decades. Thalo takes advantage of the amazing recent advances in hardware, connectivity, and algorithms to bring the magic of real-time equipment management to every system for the first time. This gives service leaders a single source of truth for the health of their entire fleet, and can change the economics of their business. Suffolk Technologies understands what it takes to operate at scale in the built environment, and that makes them the perfect partner to help us build this category.”
Dr. Brendan Hermalyn, Founder, Thalo Labs
“What if every HVAC technician had instant access to every service manual, every warranty agreement, every troubleshooting guide, and the detailed failure patterns of thousands of real-world HVAC systems? Thalo Labs is making that possible by pairing generative AI with proprietary, easily deployed hardware that creates a new layer of equipment-level data. That data unlocks cost-efficient predictive maintenance and turns complex system behavior into actionable intelligence for technicians in the field. We believe Thalo can become the intelligence layer for HVAC service across the built environment, and we are thrilled to partner with Brendan and the team.”
