A small HVAC system is a type of heating, ventilation, and air conditioning system that is designed to provide comfort in a smaller space. These systems are typically used in residential and commercial buildings that have limited space and require a more efficient and cost-effective way to maintain a comfortable temperature. Small HVAC systems are typically more energy efficient than larger systems, as they require less energy to operate and are able to provide a more even temperature throughout the space. Additionally, these systems are often easier to install and maintain, as they require fewer components and are more compact. The main components of a small HVAC system include an air handler, an evaporator coil, a condenser coil, and a blower. The air handler is responsible for moving air through the system, while the evaporator and condenser coils are responsible for cooling and heating the air, respectively. The blower is responsible for distributing the air throughout the space. Small HVAC systems are ideal for spaces that require a more efficient and cost-effective way to maintain a comfortable temperature.
