Report
Wonderful! My heat had been broken for more than a month and I was using a different company to repair it which was a disaster. My house was in the 50's and I have a toddler. I called DDM and someone came to my house that day and fixed the problem. He was personable and knowledgeable. And wish I had called them first. DDM is my new heating repair company and I would recommend them to anyone.
