ⓘ Compressor replacement requires matching refrigerant type, displacement, voltage, phase, and circuit configuration. Submit your equipment model number, serial number, and existing compressor part number for compatibility verification.

ⓘ Brand availability may vary by supplier, stock status, manufacturer policy, and refrigerant type. Compressor replacement requires matching refrigerant type, displacement, voltage, phase, and oil specification. We do not claim official authorization for every brand listed.

How do I determine if a compressor has failed?

Common indicators of compressor failure: the compressor does not start (hums or trips breaker), the compressor starts but does not build suction/discharge pressure differential, the compressor is drawing locked rotor amperage (LRA) rather than running load amperage (RLA), or the compressor is making grinding, rattling, or liquid slugging sounds. Verify with electrical measurements (resistance to ground, winding resistance) and refrigerant circuit pressure readings before condemning a compressor.

What is the difference between a scroll and reciprocating compressor replacement?

Scroll compressors are directionally sensitive — they must rotate in the correct direction or they will not pump refrigerant and may be damaged. Verify rotation direction before startup. Reciprocating compressors are not directionally sensitive. Both types require matching refrigerant type, displacement (CFM or CC), voltage, phase, and oil type. Scroll compressors are the dominant technology in modern residential and light commercial equipment.

Do I need to flush the system before replacing a compressor?

System flushing is required when a compressor has burned out (acid contamination) or when switching refrigerant types. For a mechanically failed compressor without electrical burnout, flushing may not be required, but the filter drier must be replaced and the system must be evacuated to 500 microns or lower before recharge. For burnout replacements, acid test the oil and flush if acid is detected.

What causes a compressor to fail prematurely?

Common causes of premature compressor failure: liquid slugging (refrigerant or oil returning to the compressor in liquid form), loss of lubrication (low oil charge, oil contamination, or oil migration), overheating (high discharge temperature from low refrigerant charge, high condensing temperature, or restricted airflow), electrical issues (voltage imbalance, single phasing, or low voltage), and refrigerant contamination (moisture, non-condensables, or incompatible refrigerant).
