Garry Vought
Thank you for your fast service. The gentleman was great.
Tom Sweeney
On time accurate descriptions of service pleased with tech
Long Yang
This is a new review on our AC replacement. So far, everything looks good as we’ve not had a chance to use it due to the weather.

We did place a call for a comeback visit, because the fan was running constantly after the installation of the new system. The turnaround time was very satisfactory and, above all, the issue was resolved. So, we’re happy with it.
Noel Salcedo
Very professional, knowledgeable and amazing service. Will use them again.
Arlene Johnson
We have been with Princeton Air for over 30 years. During that time they installed two furnaces and central air.

Ryan, the technician, has been out before and provided the expected outstanding service. During the visit he explained the testing steps and results. When the problem was identified he explained the options for moving forward.

We are well satisfied with the quality of service provided.
Kevin ODonnell
Technician Alberto Martino was excellent thorough and explained everything. Send him every time.
Alex Zislin

W Stuart
Installation of our new A/C system went great! The guys did just what they promised and had us back up in less than 1 day. Yet another positive experience with Princeton Air!
Jo Anne Patrick
I would recommend to my family and friends.
Ceil Reilly
I had a great experience with Princeton Air. I had an issue with a part of my healer leaking. Within an hour of calling about this problem, Dylan, the technician, arrived at my house. He soon identified the problem. The next day 3 technicians came back and replaced the faulty part.
William Welling
Jorge was friendly and did a good job. I liked him.
Albert Valentino
The service man was very nice, professional, and helpful. Excellent job.

One caveat, not related to actual service, the company canceled the appointment on me a couple of times before a service man came to my house stating emergencies – in the Spring.
Cornelius Reeves
Dominic McGinley was kind, cordial, knowledgable and professional.He has been very helpful with trouble shooting fan speed issues with my new Carrier furnace.
He’s really great, super nice technician.
Thank you.

I’ve been dealing with Princeton Air for over forty years and have always been extremely satisfied
Richard Weller
Tech from Princeton Air (Brian Hassan) showed up on time and performed yearly maintenance on our Kohler Generator. Very professional and courteous technician. Thanks for taking care of our generator like it was your own.

Just had a tech Cruise Rodriguez trouble shoot a minor wiring issue on our new Carrier furnace which was installed this week. As we were installing a new thermostat WiFi Honeywell there was a mismatch which Cruise located and rewired. System seems to be up and running with new thermostat.
Thank you Cruise for your expert help in resolving this issue.
Qi Li
Dominic is very professional and clearly knows what he is doing .
