Sharon responded shortly after I left a voicemail asking for help with a 5 year-old KitchenAid dishwasher that was not draining. He was available the next day and gave me a 9am-11am hour window of when he would arrive. He let me know there was a charge for the visit to diagnose the issue but that the charge would be applied against the final bill if there were repairs. Sharon called the next day 20 min. before 9am to let me know he was on his way and he arrived promptly. He was courteous and polite and was able to quickly extract the pump and dislodge the blockage. He also explained how I could do the same if the problem occurs again. Overall, the service was on-time, speedy, and with a minimum of hassle. Sharon was knowledgeable and provide great customer service.
