Jonathan was very thorough and professional. Thank you!
Called with heat not working and the problem was fixed on the same day. Great service!
Great work Jermaine Richmond! Professional, experienced, and friendly. Everything is working perfectly. You did a great job and I really appreciate your willingness to go the extra mile to help me fix some of the, ahem, errors I made installing my sink. Itโ€™s working great!
Update: I was contacted by Manager Will, who took the time to follow up on my experiences in detail. I appreciate the professional and thoughtful way they handled the situation and their commitment to addressing the issues I raised. Based on this follow-up and their approach to making things right, Iโ€™ve updated my rating to 5 stars.

Original review: Iโ€™ve used Princeton Air twice and, unfortunately, both experiences involved avoidable mistakes that required follow-up visits.

In June 2025, we paid about $23K for a full HVAC replacement. Immediately after installation, the system produced a high-pitched noise. When a technician came out after a few days, they found that the installation team had left the furnace manual inside the blower. As the blower ran, it was hitting the paperโ€”part of which had already burned due to friction. This is a basic oversight that should never happen, especially on a brand-new system at this price point.

More recently, we paid around $1,400 to fix a leaking shower. The plumber arrived on time and replaced a Moen 1225B cartridge quickly. However, when I used the shower later, the hot and cold water were reversed. I had to call again and wait for a return visit the same day, which required rearranging my schedule.

While both issues were eventually corrected, neither should have occurred in the first place. These are not complex problemsโ€”they are quality control issues. Having to schedule additional visits after already paying significant amounts is frustrating and inconvenient.

Overall, the technicians were professional, but the execution and attention to detail have been disappointing. I would expect a higher level of workmanship and quality assurance.

Outstanding service provided by Princeton air technician Fatmir Berisha
Excellent 5*** service by Thomas Ciaccia!
Sorry. Alberto arrived on time for annual review of my HVAC system for seasonal inspection. He made the adjustments required and as others had told mentioned that my system would work better if I added an additional part.
I was shown how to clean the water reservoir to keep it functioning properly before he left. Thank you Alberto!
Thank you for a job well done. Service people were very professional. Andre the sales representative was very knowledgeable. Kevin the plumber was great
We used Princeton Air for our commercial needs at our local tennis club and I canโ€™t begin to describe how happy we are. With company after company dropping the ball on our heating needs Princeton Air stepped up to the plate and hit it out of the park.
Dominic was extremely pleasant, professional, and thorough,. He was also quite efficient. He quickly diagnosed the situation and was able to correct it. He also took the time to patiently explain my thermostat to me. Then he signed me up as a member. So heโ€™s a pretty good sales guy too!
They are very prompt and kept the home clean. Absolutely love what they did

I would like to personally thank CHRISTIAN, ILMI, HERBERT. They were very knowledgeable and extremely professional. Any concerns I had they addressed the problem. Also thank you Chris and Marco for coming out and diagnosing the problem they guided me to a path where the suggestion was to actually replace the furnace and Ac unit. Also Joe who directly walked in to look at the panel where he exactly knew what needed to be done very knowledgeable. This team that came to my location Paterson st. was top notch service and because of this service I will use you guys to replace my other 2 units. I will also pass on your company services to friends and family for future reference. I know Herb left early while working due to family circumstances but I personally told him family comes first go ahead as a customer I will not think less you all showed great respect in my house hold. Please let Herb know I wish his family and him the best. YOU ALL AS TEAM WERE AMAZING THANK YOU SO MUCH DO NOT LET THESE GUYS GO TRUST ME THEY WORKED WELL TOGETHER.
