An AC recharge typically takes several hours to complete, depending on the severity of the charge. If the problem is minor, it could take as little as 15 minutes to recharge the AC. However, if the compressor has failed and needs to be replaced, then it could take several hours to remove the old compressor, install the new one and then recharge the AC system.

The time will also vary depending on the type of AC unit and components involved. If the work is being done by a professional, the overall time should be a few hours.

How do I evacuate my car AC without a pump?

Evacuating a car AC without a pump can be done, although it is not as efficient as having one. The best way to do it is to use a vacuum gauge and low-pressure suction line. You will need to connect the gauge to the access port of the AC system.

Once the line is connected, turn the valve to the vacuum side. This will create a suction line, which will draw out any air or moisture in the system. To make sure the suction takes out all the air and moisture, it is important to keep the unit running for a longer period of time, up to 30 minutes or so.

Once the vacuum is complete, it is time to fill the system with AC refrigerant. Such as a siphon tube, compressed air, or even a bicycle pump. All of these can be used to put the AC refrigerant into your system, but the most effective method is a bicycle pump.

To use a bicycle pump, attach it to the canister of refrigerant, and then start pumping. You may need to do a few more cycles to get the refrigerant up to the correct level, but once it is done, your AC should be ready to go.

Does vacuuming AC remove refrigerant?

No, vacuuming an air conditioner should not remove the refrigerant. It is possible that some of the refrigerant may be lost during the evacuation process, but it should be minimal. If a significant amount of refrigerant is missing after the vacuuming process, it can indicate a leak in the system.

The vacuuming process is designed to remove moisture, debris, and other air contaminants; it is not meant to remove refrigerant. Any refrigerant lost should be replenished through the service technician that performs the evacuation process.
