If your compressor is damaged or not functioning properly, the a/c system may no function to it's full potential and leave you sweating on those hot summer days. The compressor is the main part of the A/C system, as it creates the necessary pressure to push the refrigerant through to the other components and create cool air for your interior. Don't let a damaged compressor leave you without A/C and replace your damaged part today. If the A/C system is open or has not been operating for an extended period of time, it is recommended to change out the receiver/drier to keep the system free of moisture.
