Heating, ventilation, and air-conditioning (HVAC) systems account for nearly 40 percent of total building energy consumption. As energy costs climb and sustainability mandates tighten, effective HVAC maintenance has become vital for both operational performance and environmental stewardship.

Heating, ventilation, and air-conditioning (HVAC) systems account for nearly 40 percent of total building energy consumption. As energy costs climb and sustainability mandates tighten, effective HVAC maintenance has become vital for both operational performance and environmental stewardship.

Market Context The global HVAC systems market was valued at $241.52 billion in 2024 and is expected to reach $258.97 billion in 2025, with a projected CAGR of 7.0 percent through 2033. Growth is fueled by rising construction activity in developing regions and retro-commissioning of aging building stock in mature markets.

Energy Savings Through Best Practices The U.S. Department of Energy estimates that comprehensive operations and maintenance (O&M) programs—covering tasks like filter replacement, coil cleaning, and system calibration—can reduce building energy use by 5–20 percent annually. At a 500,000 sq ft commercial facility, this translates to savings of over $200,000 per year in utility costs.
