Most homeowners report spending between $3,675 and $7,155 to have air conditioning installed. This price is more typical of a central A/C unit installation rather than a window air conditioner addition which typically averages about $300. Your total cost for the job will depend on the type of system you choose.
For central air-conditioning, you'll pay $3,000 to $5,000 and up for a 2,000 square foot home. A new furnace in a central heating system costs $2,500 to $7,500 or more. If you don't need ductwork, the cost of a new heating and cooling system can be significantly decreased. In cases where new HVAC duct is required, however, you might pay $1,000 to $3,000.
