"We are so grateful for the quick and skilled response from Hillside. The leaking oil tank was catastrophic to us. We didn't know where to start. We had a rep from a well-known heating company out to the house and the response was, “You have to find someone to handle this.”. I saw the positive comments from customers on the Internet and decided to call. My call was answered by a human and our problem was taken care of with skill and professionalism within less than 24 hours. The cost was appropriate as well. Thank you. "
