Subaru Impreza 2004: Air conditioning rumble

THE airconditioning in our two-year-old Subaru Impreza wasn't working on a trip to South Australia. It was making a rumbling noise and we found out later it hadn't been gassed when we bought the car. The unit works well now, but it is still noisy. The Subaru dealership told us this is normal. What do you think?

I'M NOT convinced Subaru would have failed to gas the airconditioning before delivery, but I could believe the system had a leak. The rumbling sounds as if the compressor has been damaged after the gas leaked. The refrigerant keeps the compressor lubricated so when the gas runs out, the compressor bearings can be damaged. I would demand the compressor be replaced if it is still noisy and have the dealer check the system for leaks. As for the noise being normal, your dealer is spinning you a line.
