AC compressor replacement cost
for a Nissan Altima

Replacing the AC compressor on a Nissan Altima involves evacuating the refrigerant, removing the serpentine belt, disconnecting electrical and refrigerant lines, swapping the compressor, and then recharging the system. Cost is primarily driven by the price of the new compressor unit and the labour-intensive process of handling refrigerant, which requires certified equipment.

Cost breakdown

Parts: ~$300-$600 / Labour: ~$400-$800

What affects the price

Compressor type (new vs. remanufactured, OEM vs. aftermarket)
Model year and engine bay accessibility (e.g., 4-cylinder vs. V6)
Additional system repairs (e.g., if receiver/drier or expansion valve is replaced concurrently)

Can you do it yourself?

Possible with skill — requires AC manifold gauges, a vacuum pump, and refrigerant recovery equipment to safely handle the system, making it complex for most DIYers.

Tips before you pay

Always replace the receiver/drier/accumulator when the compressor fails to prevent new unit contamination.
Check the serpentine belt tensioner and idler pulleys for wear while the belt is off for access.
Use the correct PAG oil specified for the R-134a system and measure the amount drained from the old compressor.
