"Kevin was great! The rest of the company not so much. Kevin diagnosed the problem immediately as the thermostat, had a replacement in the truck, and completed the installation of the new unit quickly. He showed me how to program the updated version, and everything seemed to be fine - until the next morning. Turned out the replacement was defective. When I called, I was told that they might not be able to get back to me that day, but Kevin interrupted his schedule to come back and put in a new (and working) unit at no charge."

"Communication was excellent from start to finish. Everyone was very friendly and helpful from Kevin who came out for my initial consultation to Payal and Liz in the office, Robert who came out and helped us choose where everything would go and of course Derek and his crew who did the installation. They were on time and finished early the work is beautiful and the system is working beautifully so far!"

"My hot water tank was leaking and I was getting worried that it might burst. reached out to Angie's list and lucky for me that out of the many companies who could have called me. It was HSM piping and heating who called within 15 minutes. A gentleman by the name of Ackeno was asking me many questions, but all along he could hear the concern in my voice of how worried I was. At 8:00 PM. He drove the 45 minutes to my house looked at my situation and assured me all would be well until a new water heater tank was installed. Ackeno was very professional, polite, and most of all honest when it came to what the cost would be, and what he needed to do. Within 24 hours my new tank was installed. The old one was very corroded and had served me well for the 12 years that I had it. No one wants to have to replace a hot water tank but if you do Ackeno and his team will make it the most worry, free, and pleasant experience possible. For anyone needing plumbing, piping or heating work in your home or business I strongly recommend calling Ackeno at 631-507-1000. You will be glad you did."
