The HVAC full form stands for Heating, Ventilation, and Air Conditioning. It is a system that is used to provide a comfortable environment in buildings and homes. It is responsible for controlling the temperature, humidity, and air quality of a space. The system works by circulating air throughout the building or home, heating or cooling it as needed. It also helps to reduce energy costs by controlling the amount of energy used to heat or cool the space. HVAC systems are essential for maintaining a comfortable environment, and they are found in almost all modern buildings and homes. HVAC systems are also used in industrial and commercial settings, where they are used to control the temperature and humidity of the workspace. HVAC systems are complex and require regular maintenance to ensure they are functioning properly. Without regular maintenance, the system can become inefficient and may cause discomfort for those in the space.
