The Cost of Replacing an AC Unit: What to Expect

The cost of replacing an air conditioning (AC) unit varies depending on several factors such as the type of system, its size, energy efficiency, and installation complexity. On average, replacing a central air conditioning system ranges from $3,500 to $7,500, including installation. Smaller units, like ductless mini-split systems, typically cost between $2,000 and $5,000, while portable and window units are more affordable, ranging from $150 to $800. Additional costs may include labor fees, ductwork repairs, permits, and thermostat upgrades, which can further impact the overall price. High-efficiency units may have a higher upfront cost but provide long-term energy savings.
