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. It’s working great!
Georgene Berg
I reached out for a plumber in the afternoon and was told that they would be there in a few hours and they were. Mike the plumber was very nice and professional and got the job done. He had to find the leak cut into the wall and the ceiling replace a broken pipe . He cleaned up. He did not leave any mess. I would definitely recommend the company. Ask for Mike.Our cats liked him too!

Prompt professional service by Luis and Devon!

I have a Gold maintenance plan with Princeton Air which includes my Spring A/C tune-up and inspection. Daniel was my technician today, and he was excellent!
mindy paquin
Excellent technician who gave me a very thorough explanation of the problem
Tony N
On a holiday weekend, we had an odd metallic smell in our home and couldn't find the source of it but thought it must be electric or HVAC-related. Princeton Air sent Ryan to our house to help us. Despite the smell having dissipated by the time he arrived, Ryan did a thorough inspection of various possibilities and explained to us everything that could cause the smell. By the end, we did discover what the source was, and he also did a thorough inspection of our air conditioning unit and discovered an unrelated issue that he recommended a resolution for, without any pressure to commit to the work. Great service.
Salvatore Malfitano
We had an excellent experience with Princeton Air on our most recent service call. Field mechanic Daniel Sarajew was professional, knowledgeable, and extremely thorough from start to finish. The issue was clearly explained, the work was completed efficiently, and everything was left clean and in great working order. Daniel took the time to answer questions and made sure the system was running perfectly before leaving. We truly appreciate the high level of service and would highly recommend Princeton Air—especially Daniel—for anyone needing reliable and honest HVAC service.
Joseph Young
We had an emergency electrical issue on Memorial Day that was taken care of same day. We made an appointment and within two hours our electrician arrived. He fixed the issue within 10 minutes.
Ron Maruca
Ryan G. was great, really knowledgeable and very helpful in fixing the issue.
Daniel Tello
Excellent people. The tech was very smart and he was able to find the problem and fix it. We are very happy with Princeton Air Conditioning.
Rafal Listopad
Service man was very profesional and know his job very well.
Dalia Gheiler
We had a problem with our sumpump and once the technician came- he knew exactly what to do. The problem was that it was late and he had to come back with the part the next day. Which he did as Que offered. He took less than half hour to install the new part. Our sumpump was under guarantee so we paid nothing
Len B
Replaced 22 y/o heater and AC units: super happy from first contact with Weltman to the end of installation. Chris M, Rafael U, and Cesar were a pleasure to work with. Very professional and courteous. Five stars to the whole operation. This comes from a guy who doesn’t like to write reviews.
Ulises Lopez
Michael DeFeo did a great job, great personality and answer all the questions i had about my system. I 100% recommend this company.
Mau Mau
After I bought my home, I signed up for the membership program as a precautionary measure and it turned out to be a great decision. Ever since I got a complete AC breakdown which was fixed by Princeton Air technicians, a water heater leak and replacement by Princeton Air in 12h. Let's just say I'm satisfied with the services from them.
