"I had a great experience with Premier HVAC replacing my old and leaking water heater. I was impressed that they were able to respond quickly and start working on the same day as my call, especially given the severely cold weather and other plumbers being busy replacing freezing pipes. The plumber was able to work with my very tight kitchen space and narrow hallways, and without having to remove the countertop in my kitchen. I am satisfied with the installation and would definitely consider Premier HVAC for future plumbing needs."

"Called because heating system would not start up.  The company came a short time later and found out the problem was a simple fix which involved adjusting the angle of a waterline.  I highly recommend because the service was great and I had a very good overall vibe throughout the whole process.

"Jack was a lifesaver! He was the only HVAC professional we could find to repair our central AC same day. He explained everything, checked our entire cooling system, repaired it quickly and gave us tips and suggestions for moving forward and maintaining it. Also just a super nice guy. Thank you again Jack!"

"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."

"I put in the request in the evening and didn’t expect such a quick response. Klaudio was able to come out and inspect the issue and get it completed right away. He was knowledgeable about what needed to be done. Also offered advice about future repairs."
