Which system is primarily concerned with heating, ventilation, and air conditioning?

The HVAC system, which stands for Heating, Ventilation, and Air Conditioning, is specifically designed to manage the internal environment of a building. Its primary focus is on maintaining comfortable temperature levels, ensuring adequate ventilation for fresh air circulation, and providing effective air conditioning to maintain humidity and air quality.

HVAC encompasses various components such as furnaces, air conditioning units, ductwork, and ventilation systems, all of which work together to provide thermal comfort and improve indoor air quality. It is a critical aspect of interior design as it directly affects the comfort and safety of occupants in a space.

In contrast, the electrical system deals primarily with the distribution of electrical power for lighting, appliances, and other electrical needs within a building. The plumbing system focuses on water distribution, drainage, and waste management. Fire monitoring involves systems designed to detect and alert occupants to fire hazards but is not related to temperature control and air quality management that HVAC addresses.
