I can attest to the energy efficiency of these. The dual variable speed compressor system is so logical. Kid you not: electricity bill literally dropped 30% when we bought ours.
I looked at one and the store told me that it would be 3 days to a week to get repair parts because Liebherr doesn't have a very good parts network in the USA. I'm not paying $5000 for that. Id rather have a JennAir or KitchenAid that have reliable dealer support.
