A new AC unit in Arizona typically costs about $7,500 to $18,000 installed for a single system, depending on tonnage, whether it is a rooftop package unit or a split system, efficiency level, and brand. This product finder asks for your ZIP code, your property type, what your unit looks like, how the home heats, and the system size, then returns Good, Better, and Best systems with estimated installed pricing. Carrier is our most common install, and Midea, Daikin, and Goodman are also available. Estimates only, since pricing moves with demand, tariffs, and equipment availability.
