Installing or replacing central air conditioning is a major home investment. In 2026, a standard central AC installation typically costs $5,000 – $12,000, with most homeowners paying around $7,200 for equipment and labor. Full high-efficiency systems in larger homes can reach $16,000.
Average HVAC installation cost by system type
| System type | Typical installed range |
|---|---|
| Central air conditioner | $7,000 – $12,000 |
| Heat pump | $7,000 – $14,000 |
| Ductless mini-split | $7,000 – $15,000 |
| Furnace | $4,500 – $10,000 |
What drives the price
- Home size and tonnage: cooling capacity is measured in tons — roughly one ton per 500–600 sq ft of living space. Bigger homes need bigger (pricier) equipment.
- Efficiency rating (SEER2): higher-efficiency units cost more upfront but cut energy bills. A 16–18 SEER2 unit is the value sweet spot for most homes.
- Ductwork: if existing ducts are undersized, leaky, or absent, modifications or new ductwork add thousands.
- Electrical and permits: panel capacity, new circuits, and local permits vary by market.
- Labor: installation labor typically runs $1,200 – $3,500, or 25–35% of the project total.
How to keep costs down
- Don't oversize: a unit that's too large cycles inefficiently and costs more. A proper load calculation (Manual J) beats rules of thumb.
- Look for state and utility rebates — energy-efficient systems and heat pumps still qualify for incentives in many states.
- Replace before an emergency: rush replacements in a heatwave cost more and leave no time to compare bids.
- Consider repair vs. replace with the $5,000 rule: multiply the unit's age by the repair cost — if it exceeds $5,000, replacement usually wins.
