I’m back. Hentkowski Inc kept me going with my old system for a year and a half! AC was at least 30 years old. There is no one else I would have turned to for a new furnace/ AC system. They had a big job ahead of them and are delivering as promised! I cannot offer enough praise for the knowledge, recommendations and job professionally carried out! I am a single woman and we all know how that can go when we are trying to get a job done. No worries here – they respectfully answered all my questions and provided a great system. Look no further!

John B. has been servicing our HVAC equipment over the last 1-2 years. He has taken the time to get to know our entire system (which is quite extensive and convoluted,) and has been able to diagnose and fix problems accurately and quickly, which is always a great relief to us. He is simply a pleasure to work with. Approximately two years ago, prior to working with Hentkowski, Inc., one of our two basement furnaces needed replacement, and a new one was purchased and installed by another company. This last winter, the remaining furnace failed, and after John investigated the problem, we were given several options. We chose to proceed with a new furnace, and within two days Stephen H. and Mark L. were at our house with the new Carrier furnace. They were both extremely kind, professional, and thorough during the installation. They also worked well into the night to make sure that our outside A/C unit was properly connected and recognized by the furnace, so that it would be functional when spring/summer arrived. Furthermore, they fixed a venting pipe from the other furnace that was leaking from a faulty connection. They really did an outstanding job. I happily recommend John, Stephen, Mark, and the entire Hentkowski family/team to anyone who wants dedicated, honest and professional HVAC maintenance and repair.

I was very happy with Brian’s explanation of your products. Also, I was extremely happy that he said we could use the same copper tubings extending from the furnace. I thought this exemplified honesty and integrity.

I must commend you and your company for the prompt efficient response to my heater dilemma. Having no knowledge regarding heating systems, I felt comfortable and confident with my decision after your evaluation and proposal.

Turn-around time for installation was phenomenal. The service/install technicians were courteous, efficient and I very much appreciated their tidiness.

Brian, I appreciate your professionalism and assistance.
