How much does AC compressor replacement cost?
Replacing a central AC compressor typically costs $1,300–$2,800 — roughly $800–$1,800 for the part and $500–$1,200 in labor and refrigerant. If the compressor is under warranty, you pay labor only, usually $600–$1,200.
Ranges are typical planning guides — actual price varies by region, access, materials and your local pro. Always get a written quote.
| Scenario | Typical cost | Notes |
|---|---|---|
| Compressor under warranty | $600–$1,200 | Labor + refrigerant only |
| Out of warranty, 2–3 ton | $1,300–$2,200 | Part + labor |
| Large unit / hard access | $2,200–$2,800+ | 4–5 ton, rooftop, tight spots |
| Refrigerant recharge | $200–$500 | Often needed with the job |
What affects the price
Warranty status
Compressors often carry a 10-year parts warranty. If yours is covered, the part is free and you pay only labor — always check the serial number before approving a full-price quote.
Age of the system
On a unit over 10–12 years old, a $2,500 compressor is rarely worth it — a full condenser replacement at $3,900–$6,500 resets the clock on everything.
Refrigerant type
Older R-410A systems are being phased down; recharging costs more each year, and R-22 units generally aren't worth repairing at all.

How much does AC compressor replacement cost?
Typically $1,300–$2,800 installed out of warranty, or $600–$1,200 in labor if the compressor is still covered by the manufacturer's parts warranty.
Is it worth replacing an AC compressor?
Usually only if the unit is under 10 years old or the part is under warranty. On older systems, put the money toward a new condenser instead.
What are the signs of a failing compressor?
Warm air, loud clanking or ticking from the outdoor unit, breaker trips, and hard starting. A tech confirms it with electrical and pressure tests.
