The primary goal of a heating, ventilation, and air conditioning (HVAC) system is to guarantee good indoor air quality (IAQ) through proper ventilation and filtration, as well as to provide thermal comfort. The most common and classic type of HVAC system is the split system, which offers energy efficiency at a lower cost. A ductless or minisplit HVAC system is a unique, ultra-efficient HVAC system with higher initial costs. The main objectives of an HVAC system are to maintain good IAQ, provide thermal comfort, and reduce energy costs. Proper ventilation is essential for maintaining good IAQ, as it helps to remove pollutants from the air.
Additionally, an HVAC system can help to regulate the temperature in a space, providing thermal comfort for occupants. By using energy-efficient systems, such as split or minisplit systems, energy costs can be reduced.
