Alfred Sagarese
Very through
Anand Agarwal
Very professional and timely service
Virginia Tylus
The technician Alfredo is great
Sherrill Cohen
Thomas Ciaccia was the representative from Princeton Air who came to my house to diagnose the cause of non-functioning air conditioning. He provided excellent service that included testing two AC units, explaining how to use relatively new thermostats to best coordinate with the AC, presenting alternative ways of addressing the AC problems, and answering my many questions. I learned a great deal from his visit. It was well worth the reasonable cost.
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.
Jerry Muntz
Wilver was great. Knowledgeable, polite and efficient.

We could not be more impressed …
MariaTeresa Maisano
Stevin was very helpful and clearly explained the procedures he did for the AC unit. Also he pointed out what needed to be taken care of in the near future.
Barbara Delorey
Diagnosis of a leak, good service, honest and thorough! Excellent service person, Jonathan and Jesus.
Vaughan Farrie
Service personnel arrived as scheduled and preformed the maintenance as included in our contract without and question, problem or difficulties.
Thomas Measey
Jonathan did a great job servicing our AC, heater and water heater all during the same visit. Very knowledgeable and professional. Would highly recommend.
Benjamin dela Pena
Dominic was prompt, efficient, and most importantly, very friendly. He showed me exactly what was wrong and explained why. The fix was just as quick. Thanks Dominic and Princeton Air!
Andrea Purcell
The Tech arrived on time, quickly figured out the problem with my AC and fixed within an hour. Pricing reasonable and professional service. Highly recommend!
Gary Lynn
Cruise was great! He addressed our AC issue quickly and professionally.
Paul Foster
We’ve always been satisfied with McAllister and our recent experience since the merger has not changed that. We needed a new condenser for the A/C and they had a cost effective solution and were able to install it quickly.
Arie Blum
Very efficient and on time
Mary Lou Ferry Wimmer
Princeton Air condition was extraordinary!! I received a very fair quote immediately after Inspection of my HVAC systemby their talented technician. Their technicians were prompts, professional, and polite. They installed a new system with precision and followed up Professionally. Totally proud to work with Princeton.!!
joey floresca
Ryan G came by and provide tips and recommendations so thorough and with full clarity that I believe will benefit in the long haul. Because of this, I was confident to re-sign up for their maintenance program. He was a true professional who is highly knowledgeable and enthusiastic with the work that he is called to do.
Christine Brown
Jose and Corey were a great team and genuinely seemed to care about solving our issues.
Jennifer Popper
I had A/C installed in May, but waited to write a review to see how effective the units can be once it's hot out. Now that I've gone through a couple high temperature days where I turned the mini splits on, I can post a review that I am completely satisfied with the installation by Princeton Air Conditioning and the ease of usage of units. I also will add that it was a pleasure to have Mike C. and Christian J. on the job; they, along with the crews that were on site over the course of the two days, were professional, communicative and upfront. I'd recommend this company to anyone looking for services.
Deb Cambria
Professional and friendly staff
Gregory Zotian
Air conditioning wasn't working and they came out and got it fixed within a day. Ryan did a great job making sure everything was up and running quickly.
Gerald Novak
The job was done smoothly and efficiently and right on time
Nancy Greening
Ryan G got our old air conditioner working again quickly during a bad heat wave and, when we were ready, he explained all our options very well and laid the groundwork to make it easy for us to have installed a new air conditioner. Plus he rescued our cat three times when our cat tried to get out through the garage. He was very kind to all our pets and to us. Thank you, Ryan G!
