Customer Reviews
Derrick Sokolowski
They are a great company with a knowledgeable leader. You will not see their advertisements since they do word of mouth which literally speaks for the company and shows how engrained they are within the community. I would recommend them for your Heating and Air conditioning needs.
Diana Vock
We are so grateful that I called Hentkowski, Inc. Two other HVAC companies had performed diagnostics on our non-working Heat Pump. Company "A" said it was the compressor and the electrical panel - $12,000 to repair. Company "B" (who installed the unit) gave the same diagnostics but said $5000 to repair, though they recommended that we replace the inside and outside unit at a cost of over $20,000. Kim at Hentkowski used the serial number on our unit and determined that we were still under warranty for parts. John's diagnostics concluded that it was only the electronics. He did the repair and the unit is running better than it has in years. I highly recommend Hentkowski, Inc. Kim and John are awesome!

Hentkowski did an excellent job of doing the annual maintenance check of our HVAC system. Mr. Salman, the technician, did an outstanding job of tuning the system and making sure it is working properly. His technical expertise and knowledge was impressive, and his work was thorough. He came to our home on time, treated our home with respect, answered my questions to my satisfaction, and finished the work in a timely manner. I have no hesitation in recommending Mr. Salman and Hentkowski to anyone who needs to have their HVAC checked.
Paul Pomeroy
I cannot say enough good things about the quality and professionalism of this company. If you are need of HVAC services you should strongly consider this company. I have needed both routine maintenance and more comprehensive services and both have been consistently delivered with great expertise and for a fair price. Hentkowski Inc has also been, in my experiences, highly ethical and honest in how they conduct their business. Highly recommend.
UPDATE: I went to write a review and forgot I had done one already several years ago. So I'll instead take a moment to reconfirm how excellent and ethical this company is. I'll also put a plug in for Sal who has now been to our house several times and continues to be knowledgeable and respectful each time we see him.
Korinne Ross
This is such an easy review for us. The quality of work is matched by their respect for your home. Very thorough and informative, making sure we understand our heating and cooling systems. We converted to gas from oil. Our house is warmer than it ever was! Just the kindest people to work for us! Thank you!
