HVAC (Heating, Ventilation, and Air Conditioning) system equipment encompasses various components designed to regulate indoor climate and ensure comfort and air quality in residential, commercial, and industrial settings. Key elements include furnaces or boilers for heating, air conditioners and chillers for cooling, ventilation systems to manage airflow and filter air, and thermostats for precise temperature control. Advanced HVAC systems often incorporate energy-efficient technologies and smart controls to optimize performance and reduce energy consumption. These systems play a crucial role in maintaining a comfortable and healthy indoor environment, regardless of external weather conditions.
