The cost to install central air conditioning in a typical home generally ranges from about $5,000 to $12,000, with most homeowners spending around $7,000 for a complete system including installation

Cost Breakdown

• Central Air Unit Only: $1,900 to $5,500 depending on size and brand

• Installation Labor: $1,500 to $3,500, varying by complexity and region

• Ductwork (if needed): $3,000 to $5,000 or more, especially if new ducts are required or existing ducts need upgrading

• Permits and Materials: $300 to $800

Factors Influencing Cost

• System Type: Split systems (indoor and outdoor units) are common and cost between $1,900 and $4,200 for the unit alone, while packaged systems (all components outdoors) range from $2,300 to $5,500

• Unit Size and Efficiency: A 2.5 to 3.5-ton unit is typical for a 2,000 sq ft home. Higher SEER (Seasonal Energy Efficiency Ratio) ratings increase upfront cost but save on energy bills long-term. For example, SEER ratings above 18 can add $1,000 to $2,000 but improve efficiency

• Ductwork Needs: Homes without existing ductwork or with inadequate ducts face higher costs, sometimes up to $16,000 for extensive duct installation or replacement

• Brand: Premium brands like Trane or Carrier cost more upfront but offer better warranties and features, while more affordable brands like Goodman or Rheem start around $3,000 for the unit
