There are several types of central air conditioning units, each with its own features and benefits. Here are some of the most common types, along with an estimate of their cost:
Split system. Split systems are the most common type of central air conditioner and are relatively affordable, with an average cost of $3,500 to $7,500 installed.
Packaged system. A packaged air conditioner contains all of its components in a single outdoor unit, making it a good choice for homes with limited indoor space. Packaged systems are generally more expensive than split systems, with an average cost of $5,000 to $12,000 installed.
Ductless mini-split. A ductless mini-split air conditioner is a type of split system that doesn't require ductwork. Ductless mini-splits are a good choice for homes without ductwork or for room additions, but they can be more expensive than other types of systems, with an average cost of $2,000 to $14,000 installed.
