The definition of A/C Direct is a term used to describe a system of air conditioning that does not rely on a traditional central air conditioning unit. Instead, it uses individual air conditioning units in each room or area of the home or building. This type of system is becoming increasingly popular due to its efficiency and cost savings. A/C Direct systems are designed to provide air conditioning in each room or area of the home or building without the need for a central air conditioning unit. This means that each room or area of the home or building can be individually cooled or heated, depending on the season and the needs of the occupants. The individual air conditioning units are usually connected to a single control panel, allowing the user to adjust the temperature in each room or area. This type of system is often more energy efficient than traditional central air conditioning systems, as it does not require a large amount of energy to cool or heat the entire home or building. Additionally, A/C Direct systems are typically less expensive to install and maintain than traditional central air conditioning systems.
