What drives the cost
Installing central AC into a home often includes more than just the unit. Here's the breakdown:
| Cost area | Typical range |
|---|---|
| AC unit + install | $4,200 – $8,000 |
| New ductwork (if none) | $3,000 – $8,000 |
| Electrical / panel work | $500 – $2,000 |
| Thermostat and controls | $100 – $400 |
Ductwork is the big variable
Adding central AC to a home without ducts is the most expensive scenario. If you have existing ducts, the cost drops significantly.
Example
Central AC in a home with existing ducts
Installing central AC into a 1,800 sq ft home that already has ductwork typically runs around $7,000–$8,500 including the unit, labor and a permit.
