Kathy Sell
Thanks so much for the EXCELLENT service from Norman. He was very knowledgeable and so friendly. Really nice guy. Thank you Norman and thank you Princeton Air.
Nancy Carey
The technician was absolutely positively wonderful. Was very kind, thoughtful and most of all patient. Found the problem quickly and I was back in business. It is because of him I will be using Princeton Air for all of my plumbing issues and will be scheduling a maintenance appointment requesting this same technician. Thank you again for such wonderful service. I happily recommend this company.
Mindy May
We moved into a new home and had no idea about the heating system. The technician. Dominic, took time to show us the system and made good recommendations.
Now 6 months later we had Maurice Gaines technician, come do a maintenance check on our air conditioner. He found a problem and fixed it immediately. Now the unit will run smoother and is in good working order
We now feel we have good knowledge of the workings and look forward to working with Princeton Air for our future needs.
Sandra Finalet

Donna Limeri
Dominick from Princeton Air arrived on time and immediately identified himself. He was polite and courteous from the get go. He had to troubleshoot my ac unit which stopped working in the middle of a heat wave ( Murphy’s Law). He gave me the bad news that it would be very costly to repair unit as unit is 22 years old and there are numerous problems. I decided to go with a replacement unit, stay tuned…
Kirk Windish

Tanzil Ali was very professional and helpful, answered all of my questions. I would recommend him to everyone I know. I would like to see him again next time I need service.
Debbie Bickham
Dominic was fantastic. My air conditioning stopped working I called the Company at 9:30 and Dominic was here at 3:00 he quickly diagnosed the problem, had everything working again in no time, and checked the entire system to make sure everything was running properly.
Professional, knowledgeable, and a pleasure to deal with. I truly appreciated his prompt response and excellent service. Highly recommend!
