How much does it cost to replace a central air conditioning unit?

Homeowners can pay between $500 and $4,000 for central air conditioning.

When added to an existing forced-air heating system, central air for a 2,000-square-foot home costs $3,500 to $4,000 and can be done by two technicians in two to three days, often with little or no change to the ducting. For a house that needs ducts, the costs and work time double.
