The global smart thermostat market is entering a high-growth phase driven by rising energy-efficiency awareness, accelerating smart-home adoption, tighter building-energy regulations, and rapid advances in connected-device intelligence. New research from Kings Research indicates the market has already moved from a solid base toward a significantly larger market by the end of the decade — creating major opportunities for OEMs, HVAC integrators, utilities, and energy-services firms.

The global smart thermostat market size was valued at USD 4.67 billion in 2023 and is projected to grow from USD 5.48 billion in 2024 to USD 17.22 billion by 2031, exhibiting a CAGR of 17.76% during the forecast period.

Executive summary

According to Kings Research, the smart thermostat market is projected to record steady expansion during the forecast period. Wireless and connected segments are already commanding a large share of revenue, while both new installations and retrofit demand contribute to near-term expansion. North America remains the largest regional market.

Market growth drivers

Smart thermostats are benefiting from multiple, overlapping demand drivers:

• Energy and cost savings: Consumers and businesses are increasingly sensitive to energy bills and seek automatic, data-driven temperature control to reduce HVAC energy use.
• Smart-home mainstreaming: Improved interoperability with voice assistants, home hubs, and smart meters makes smart thermostats a low-friction entry point for whole-home automation.
• Policy & incentives: Utility rebate programs, building-efficiency mandates, and incentive schemes for demand response encourage installations in both residential and commercial segments.
• Technology advances: Machine learning optimization, occupancy sensing, humidity control, zonal integration, and remote diagnostics raise the value proposition.
• Installer & OEM channel expansion: HVAC manufacturers and resellers are broadening assortments and offering bundled HVAC+smart control packages.
