Central Air Installation Cost
Installing central air conditioning is a major home investment. Most homeowners pay $3,500 to $7,500, though complex installations can reach $10,000+.
Key Cost Factors
Home square footage is the primary cost driver. A 1,500 sq ft home needs a 2.5-ton unit, while 2,500 sq ft requires 4+ tons. Higher SEER ratings cost more upfront but reduce monthly bills.
Ductwork
Homes lacking ductwork add $2,000 to $5,000. Existing ducts in good condition save substantially. Ductless mini-splits are an alternative where ductwork isn't practical.
Timeline
Most installations take 1-3 days. Complex projects with new ductwork may take a week. Schedule in spring or fall for better pricing.
Saving Tips
Get at least three quotes. Ask about manufacturer rebates and utility incentives for high-efficiency units.
