The answer to 'how much to replace AC repair' is that the cost can vary widely depending on several factors. Typical ranges for a full AC system replacement can be anywhere from $3,000 to $10,000 or more, but the exact price will depend on the size of your home, the efficiency of the new system, the complexity of the installation, and your local market rates.
Some key factors that influence the cost include the type of AC unit (central air, ductless mini-split, etc.), the SEER rating for energy efficiency, whether ductwork needs to be replaced, and the labor rates in your area. Additionally, the age and condition of your existing system, as well as any necessary electrical or structural upgrades, can also impact the final price.
