“Jay and Mike were wonderful. They came to my house in a snowstorm. They worked in the basement that had flooded and the workers from the sewer cleaning company were here at the same time. They said that it was no problem. They were very hard working. Watching them go up and down the stairs was exhausting. They were both amenable and respectful. I would recommend your company and these workers to anyone.”

“I want to say that the experience with Harriman Heating has been nothing less than outstanding. Rob and Mike were over on Monday and first let me know the procedures that were to be done. Before they started they laid tarp on the steps and through the basement. Once they got started, they went about their business. They took their time and finished about 5:00. Rob explained to me that they would be back on Wednesday to complete the job. I received a call from Emily on Tuesday asking if I could move the appointment up by one day. I advised here it would be no problem. Rob showed up and went about the business of finishing the job in a very professional manner. He had to make a few adjustments on some material that was not right. While he was doing that he took the time to answer some questions from a neighbor inquiring about possibly doing a job for her. After Rob finished he made sure everything was working and walked me through what was done and explained the filter systems and when they should be changed. He also explained that since the temperature was below 60 that it made need refrigerant later in the summer and if so, to just call the office. All in all Harriman Heating has an outstanding employee in Rob Troy. I will be calling Harriman Heating for any other mechanical or plumbing work that needs to be done.”
