Compressors

What’s a car air conditioning compressor?

The compressor is a belt driven engine-mounted pump that serves as the heart of your car’s air conditioning system. It draws refrigerant gas from the Evaporator, compresses it into a hot gas and pumps it to the Condenser.

We offer parts and restoration services for a wide variety of GM A5 and A6 compressors, clutches, clutch brushes, clutch bearings, idlers, manifolds and shaft seals. Have a question? All you have to do is call or email.
