A few synonyms for central air conditioning include whole-house air conditioning, ducted air conditioning, and central HVAC. Some other terms used for cooling systems that cool specific areas directly include window air conditioning, portable air conditioning, and split-system air conditioning.

Regardless of the terminology, these systems all serve the same purpose of providing a comfortable indoor environment.
