The answer to 'how much to replace central air' is that the cost can vary significantly depending on several factors. Typically, the total cost to replace a central air conditioning system can range from $4,000 to $12,000 or more, including both the equipment and installation.
The main factors that influence the cost include the size of your home, the efficiency rating of the new system, the complexity of the installation, and your local labor rates. Larger homes require more powerful and more expensive systems, while higher SEER (Seasonal Energy Efficiency Ratio) ratings correlate with higher upfront costs. The complexity of the installation, such as whether ductwork needs to be replaced, can also impact the final price.
