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.
As a long time customer of Hentkowski, Inc., we have always relied on the excellent service and professionalism your company has provided. The installation of the new boiler was no exception. The team of Steve Hentkowski, Steve Harris and Mark Lang was top notch. Great care was taken to protect our floors, removal of the old system and installation of the new went like clockwork and cleanup was fantastic. Please pass on our thanks to Steve, Steve and Mark for their excellent work.
I was very satisfied with Brian who suggested the units we had installed. Also, the men who installed the air cleaner were efficient and polite. Good Work!!
Your service is exceeded by no other! Thanks for your immediate attention to a bad situation. Anything I need pertaining to home heating is Hentkowski!
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.
Couldn’t ask for a better experience. The job was started and finished in a timely fashion, the workers were professional and neat. The unit works fine and does everything the salesman said it would.
