At Your Service was recommended by the local Thermador distributor as a company that would be able to repair the automated downdraft vent for our cooktop. The technician, Brad Cornwell, arrived on time. The company also sent a reminder phone call, which is pretty standard, but still nice. He diagnosed the problem right away and was able to repair it, all in about 45 minutes. Brad was friendly, professional, and courteous. This company specializes in large, high-end appliances. I would call them again without hesitation.
