Average AC Installation Cost in Wilmington, NC
The cost to install a new central air conditioning system typically ranges from $4,500 to $12,000. This range varies based on several factors, including the size of your home, the efficiency of the system, and the complexity of the installation. Smaller homes may only need a basic unit, while larger or multi-story properties often require higher-capacity or zoned systems for optimal cooling.
What Affects AC Installation Cost?
Several variables influence the total cost of AC installation. First, the size of your home determines the required system capacity. Larger spaces need more powerful equipment and potentially more extensive ductwork. The type of system central air, ductless mini-split, or heat pump also impacts pricing. High-SEER (Seasonal Energy Efficiency Ratio) systems offer greater long-term savings but typically have a higher initial cost.
If your existing ductwork is outdated or missing, installing or upgrading it will add to the project cost. Other features, such as smart thermostats, add an upfront investment but enhance control, comfort, and energy efficiency.
