Nick is a great asset to KNZ! He is friendly, knowledgeable, prompt and always able to trouble shoot issues with my Navien hot water heaters even though KNZ did not install them. They did install our boiler with the HVAC system and I have never had any issues with that system this far!

Very happy with the service received from Nick with KNZ Heating. Always great service and communication from Nick. He's always done a great job and willing to answer any questions you may have and may have a suggestion or two to keep things going. Highly recommended !

Keith was amazing to work with also had a great team for installation and very informative about the process. During installation my wife was present and they answered all questions and kept her up to date on schedule and progress. Very personable and professional. Highly recommend this company. Thank K n Z for a great experience.

Our 30 year old Weil-Mclain boiler broke down and the problem was something I was unable to fix on my own, so gave KNZ a try. I saw they had mostly positive reviews here and I liked their comments here too, to both positive and negative reviews. They sent their tech Nick out, who was here within a few hours, earlier than I had expected. Nick found the problem within 30 minutes. It was a bad fluid level module. He said it would cost $850 to fix it, which I thought was a bit high, but it had to be fixed asap so gave him the ok. He ordered the part and it came in the next day and he installed it. He was probably here, a total of 3 hours for both days. Now my system is back to running normal, thank goodness. Nick is very sharp and knowledgeable and he did a great job. I didn't get an itemized
