AC compressor replacement cost varies by system and is confirmed after an on-site diagnosis; a diagnostic fee applies (often $79, with occasional $179 diagnostic specials) before we provide a firm quote. Most of the cost comes from the compressor part and the labor to recover refrigerant, replace the unit, and recharge the system. Our technicians regularly handle compressor replacements throughout the Seattle area. Sometimes a failed start component can look like a bad compressor, so we always test before recommending replacement. 24/7 emergency service is available when you have no cooling.
Your final quote depends on:
- Refrigerant type and required charge amount
- Compressor type (single-, two-, or variable-speed) and brand match
- Existing warranty coverage on parts
- System age and whether related components must be updated together
Schedule a diagnostic so we can verify the fault and give clear repair-or-replace options in writing.
