"My hot water tank rental was leaking, I called the customer service number and was able to get a service tech onsite the same day. The service technicians name was Jake Montreuil. He called ahead of time to tell me the exact time he would be arriving, and he came at that time. He was very professional, he explained to me what the problem was and was very kind and courteous. He even entertained all of my toddlers questions towards him which was much appreciated. He left his work site clean and tidy, I couldn't have asked for better service. Definitely 5 stars!"
