Replacing a home air conditioning (AC) compressor is a complex process that requires specialized knowledge and tools. It involves removing and disposing of any remaining refrigerant, disconnecting and taking out the old compressor, installing the new one with the necessary accessories, and recharging it with refrigerant. All in all, it usually takes between four to six hours to complete this repair. If you include the time spent driving to collect the compressor, it can take up to five hours.
On the other hand, if you need to replace an entire system, the process can take much longer. It can take between three and five days, as the unit itself will be replaced in one day, while replacing the ducts can take up to four days depending on the scope of the project. When it comes to predicting when an AC compressor might fail, the season of the year is a major factor that affects the cost of replacing it. However, no one can accurately predict when an air conditioning compressor will break down.
