A central air conditioner unit installation costs between $3,200 to $7,800 on average for homeowners. The primary elements influencing the cost of an AC unit are the square footage of your home, the preferred brand and the SEER level you select. A 2.5 ton AC unit would be appropriate for a 1,300 to 1,600 square foot home, and the typical installation cost would be approximately $3,570, with the unit alone costing around $1,285.
