Condenser part
Compressor
What it does
The compressor is the heart of your air conditioner or heat pump. It circulates refrigerant through the system to move heat between your home and the outdoors.
Why it fails here
Overheating, electrical issues, low refrigerant, or normal wear over time.
- Average lifespan
- 10–15 years
- Typical replacement cost
- $2,000–$5,500
Worth an upgrade look: On an older system, a failed compressor is the classic repair-vs-replace crossroads — we quote both, side by side.
