Ruchit and Neha Patel

Had both my original home furnace units replaced after 15 years. Dong Lin was the lead technician and was professional, courteous and knowledgeable. He and his team did an excellent job removing the old units and installing the new units. And followed it up with an explanation on the unit and walking us through filter maintenance of our specific unit. I’ve use Princeton Air for my HVAC maintenance as well as for 15 years and they have always done a good job and even at times where things were not right the first time out they would promptly come back and make the appropriate adjustments.

Lisa Cohan

Pricey, but good. Since my last electrician didn’t show up for the appointment, I decided to go with a company. Anthony is the electrician they sent, and he is whom I will be requesting going forward.

Evan Hock

Booking was easy. My technician was friendly and quickly resolved the issues with my A/C unit.

Ronda Siegel

Ryan pinpointed issues during HVAC repairs. He is also very professional and honest.

Francois Doura

Dong Lin was very knowledgeable, experienced, full of energy, friendly and very neat. It is with great pleasure that I give him a five star rating for a well done job.

Matthew McKeown

I scheduled a maintenance call for my HVAC unit. Alberto was the technician who came. He did a great job explaining the issues with the unit given it is 10 years old and offered recommendations to keep it in good shape.

Mona Kay Rifi

Princeton Air went above and beyond fixing my broken dehumidifier. Their technician spent a lot of time troubleshooting the issue and even got on the phone with the manufacturer’s technical support to get to the bottom of it. Once they determined it was a warranty issue, they took the extra step of hauling away the old unit, picking up a replacement, and installing it themselves — no extra hassle on my end. It’s working perfectly now. Great service and real dedication to getting the job done right. Highly recommend!

Jim Walters

The technician Alberto was amazing and very informative, professional and knowledgeable. Princeton Air never disappoints with the quality of technicians they hire.

Jennifer Eisenberg

Jason was extremely patient answering all my questions regarding the new water heater I had installed. He was amazing and very careful throughout the whole process. He and his team were very efficient and clean. Overall, I was highly satisfied with the work they did. I have been using Princeton Air for years and am pleased with their service.

Deepti Naware

Ed and his team did a great job and went above and beyond what was expected. Very polite and courteous throughout the install which lasted several hours. New AC is working great. A big thanks to the Princeton Air team!

Patty Hu

We truly appreciate the outstanding service provided by Princeton Air. Your team was professional, efficient, and customer-focused throughout the entire installation process. We especially appreciate that you were able to move our installation up by five days, sent a crew of 4–5 technicians, completed the entire furnace and A/C installation in just one day (about 8 hours), and carefully protected our floors and property during the work. On top of that, Princeton Air offered a very competitive price and excellent overall value.

Jorge Lay was great. He found the issue with the HVAC in less than 5 mins and fixed it. Best part was that he spent tthe next 20 mins ensuring the issue doesn't recur.

Sam and the rest of the team from Princeton Air did a great job installing our new furnace and A/C. They arrived promptly and immediately started. They made the whole thing painless. I highly recommend them.

Ryan G was just here today preforming routine maintenance on our unit. He gave us a full rundown on everything he did and what we can expect in the future!

Maurice Gaines who cleaned and serviced my air conditioner was fantastic! He was fast, respectful and very fast with the repairs.

He made me feel like I was getting the full respect and honesty I so needed for something so important and really appreciated the time he took to explain every and answer all my millions of questions. Also Princeton Air communications were fast and accurate , leaving no question unanswered as to timing and confirmation of appointment. I’m so happy with their staff and with Maurice- he’s a gem!
Thank you!
