The cost of a new central AC unit will vary depending on the size and type of unit you need. A basic system will typically start at around $1,500, but more elaborate systems with features like zone control can cost upwards of $10,000. Installation costs will also vary, but expect to pay at least $1,000 for a professional installation. If you're doing it yourself, be sure to factor in the cost of materials like ductwork and insulation.

Central AC usually costs anywhere from $2,000 to $10,000. The cost varies depending on the size of your home, the brand of AC unit, and the features you choose. Some people try to save money by installing a window unit instead of a central AC system. But in most cases, it's actually cheaper to install a central AC unit than to buy and install multiple window units. Plus, central AC is more efficient and will keep your entire home cool instead of just one room. So if you're thinking about getting a new air conditioning system, it's definitely worth considering a central AC unit.
