A HVAC Equipment Database is a collection of information related to the heating, ventilation, and air conditioning (HVAC) systems used in buildings. This database typically includes information such as the type of equipment, its size, capacity, installation date, and any maintenance records. This information is used to ensure that the HVAC system is operating properly and efficiently. The database also provides a way to track the energy usage of the system, allowing for more efficient operation and cost savings. Additionally, the database can be used to identify potential problems with the system, such as poor air quality or inadequate heating or cooling. By having this information readily available, it can help to prevent costly repairs and ensure that the system is running at its optimal level.
