HVAC Systems Market Outlook:
HVAC Systems Market size was over USD 240.91 billion in 2025 and is poised to exceed USD 452.22 billion by 2035, growing at over 6.5% CAGR during the forecast period i.e., between 2026-2035. In the year 2026, the industry size of HVAC systems is estimated at USD 255 billion.
With the rising stringency of carbon restrictions, there will be an increasing demand for energy-efficient buildings. As per the International Energy Agency, in 2022, building energy efficiency investments climbed by almost 14% to exceed USD 250 billion. Energy-efficient HVAC systems are therefore becoming increasingly necessary for both new construction and building retrofits. For instance, buildings that have undergone retrofitting can cut their energy use for heating and cooling by 50-90%. In addition, a well-maintained and energy-efficient HVAC system can significantly cut energy usage, and enable commercial buildings to lower their operating expenses and their carbon impact. Furthermore, it is anticipated that tax breaks and government programs that encourage the installation of energy-saving devices will promote the usage of HVAC systems and will have a favorable effect on HVAC system market expansion.
