EGegeg Installation was done on time. The mechanical work was really well done and they cleaned up after themselves. They could have used more training on the new electronics, specifically the iComfort S30 and the iHarmony zoning. A defect in the compressor took a long time to diagnose but was replaced no questions asked. They could have also been more responsive...I had to prompt them more often than should have been the case. Overall this dealer is just a whisker shy of excellent in most areas and I would recommend it highly.
