What a new HVAC system costs
Most full system replacements land between $8,000 and $15,000. Here's what sits behind that range.
| Job | Range |
|---|---|
| Full system (AC and furnace) | $8,000 to $15,000 |
| AC only | $4,000 to $7,500 |
| Furnace only | $4,000 to $7,500 |
| Air-source heat pump system | $8,000 to $16,000 |
| Dual-fuel (heat pump with gas backup) | $10,000 to $18,000 |
What moves the price
- Size. A bigger home needs more capacity. Oversizing wastes money and makes the house clammy, so ask for a load calculation.
- Efficiency. Higher SEER2 and HSPF2 ratings cost more up front and less every month.
- Ductwork. Repairs add roughly 10%. New ducts can nearly double the job.
- Electrical and access. A panel upgrade, a tight attic or a crawl space adds labor.
- Timing. Emergency installs in peak heat or cold cost more than a planned spring or fall swap.
Rebates and financing can change the math. Ask every company what applies, and get the final price in writing.
