Ryan G arrived promptly to my home to see why my air conditioning unit wasn't working. He clearly explained upfront the charges for diagnosing the problem. He quickly discovered the source of the issue and showed me pictures of the clogged a/c pipe and explained the work he would be doing. After the work was completed, he showed me how much debris he pumped out of the pipe and explained the charges which were very reasonable. I was thoroughly happy with the service that Ryan G provided. His descriptions and instructions were very clear. I would highly recommend Ryan G. & Princeton Air to all !
Our tech Dominic was Great!!
Princeton Air did a great job installing my new Carrier Furnace and A/C system. Devin and Woody were really polite and professional. Great experience and thorough cleanup. Also, Joe was a really professional electrician, and a really nice guy.
Iโ€™m very happy with my new system.
Thank you Princeton Air.
Latrell and Norman two very hard workers ran into situations replacing a compressor on our air conditioning unit but kept us informed as to their progress. It was frustrating for them on hottest day of year but they kept their professional and customer service attitudes up in a pleasant manner. Two excellent maintenance service repair professionals.
Excelente servicio, el tรฉcnico Dominic muy profesional y muy amable. 100% recomendable
Ali was great! We have a very confusing system here at the office and Ali went over and above and let us know what happened, what he did to fix it, and an action plan going forward. He also provided with solutions and recommendations to corporate in his work order, providing me with peace of mind that our company and the people who need to know what is going on.
Back to normal
They sent someone out when my Central Air died in the middle of a heatwave; it turned out to be frozen so they had to return after it thawed, but everything was timely and I felt well taken care of. Dispatchers, office staff and my tech, Cruise, were all excellent. I was up and running by noon!
Very knowledgeable and professional Navien tech.
Maurice Gaines was friendly, helpful, knowledgeable and efficient! I've used Princeton Air's services a few times now and it's always been a good experience.
Latrelle did an excellent job
I had issues with my A/C unit that would sporadically not turn on and wouldnโ€™t be able to reach the desired set temperature. I had a service contract with the utility company , who I called out 3 times to fix the issue and each time they couldnโ€™t find anything wrong. This time I called Princeton Air, was able to book online and they came out the next day. Ryan came to my house and listened to the entire history of my A/C issues. He was able to troubleshoot and quickly found there was a wiring issue which he was able to correct that day. He educated me on my unit and explained in detail to me everything he did along the way. Thank you Ryan, you are very talented in your skill.
Maurice was terrific and solved the problem very quickly. I highly recommend Princeton Air.
I like to thank Dylan very much. He came to service my AC unit and he found that it was not in service. The refrigerant had leaked out through the coils. Coils were shot. I would have never thought this being a 2-Year-Old AC unit. But fortunately, I did get a service policy and it was under warranty which saved me. Thank you Joe and Tyler also and the girls in the office are just wonderful and will definitely work with you. I've been with this company for over 20 some years and they've always been professional…
Our Tech Dominic was Awesome!! Thank you so much!!
On time. Completed work on all units … Heater, air conditioner, and hot water heater … Within the time frame.
After a few mishaps, Princeton Air came through and got my AC system running when the temperatures are soaring.

Thanks to Will and my technician, Alberto, for getting everything fixed.
Responsive, knowledgeable, dependable, & honest. Thank you for getting out heat up & running!

Update:10/12/18
Chris S got the heat last year and remembered when he arrived today, asked if it had a problem since. He came back to do a PM on the heater and while he was waiting for me to arrive, he opened up the air conditioner to inspect it and saw the coils were filthy. Took out his hose and cleaned them. Then when done, did the heater PM and then โ€œsaid I just want to verify that ringing noise went away. Your house will cool much faster now!โ€ I really like what Princeton air offers, quality and care, diagnose and fix. Not rushing to get to the next job. Theyโ€™re so good I got the year round service plan.

Update may 2025&2026
Maurice is fantastic.
Prompt and knowledgeable. Great technician.
There was an urgent need for a mold problem to be handled in a bathroom. They quickly identified the problem, tested the seriousness, and took care of it – in a very timely fashion. They communicated with me all along the way so I could fully comprehend what was going on. All the people were very knowledgeable, pleasant and accommodating. My experience with them was excellent, and I would highly recommend them.
Eric M. was prompt, professional, courteous and quite helpful. I become a better consumer when I understand the problem & possible solutions. Eric was willing to answer my questions and made me feel secure that he would follow up to help fix our problem.

Notice a problem with the humidity in my home, called and got a service appointment in the same day.

Frequently Asked Questions

How quickly can Princeton Air complete an AC repair in Princeton?

Most AC repairs in Princeton can be finished during one service call since our technicians arrive prepared with common parts and diagnostic tools. Response times are especially fast during Princeton’s hottest summer days. Cooling failures create urgent situations. For complete system breakdowns, we offer around-the-clock emergency service because we know how quickly a home becomes uncomfortable without air conditioning. Our scheduling prioritizes same-day service whenever possible. Comfort can’t wait.

Does Princeton Air service all AC brands in Princeton?

Absolutely. Princeton Air technicians work on all major residential AC brands and system types found throughout Princeton, NJ. We train our team to understand how cooling systems function as a whole rather than focusing on just one manufacturer. This leads to better diagnostics and more reliable air conditioning repair in Princeton no matter what equipment you have.

How do I know whether to repair or replace my air conditioner in Princeton?

The decision comes down to your system’s age, the scope of the problem, and whether the repair cost makes financial sense compared to what your equipment is worth. A newer system with a single component failure is usually worth repairing. An older unit with multiple issues or major component damage often points toward replacement. Our technicians in Princeton assess your AC’s condition, efficiency, and repair history to give you an honest recommendation based on what actually makes sense for your situation and budget.

What’s the most effective way to prevent AC problems in Princeton?

Regular professional maintenance visits make the biggest difference in preventing AC breakdowns. During these annual service calls, technicians clean dirty coils, verify refrigerant levels, and inspect electrical connections. They spot problems while they’re still small and manageable. Princeton homeowners often join maintenance programs for year-round system care that keeps cooling reliable through New Jersey’s humid summers and protects their investment over time.

What should I do if my AC keeps breaking down even after repairs?

The same problems keep coming back? It’s usually a sign that the real issue isn’t being addressed. Maybe your system is the wrong size for your home, airflow is restricted somewhere in the ductwork, or multiple components are wearing out together. Instead of fixing the same thing over and over, we dig deeper to find what’s actually causing the pattern of failures. Princeton’s humid summers are hard on AC systems, so we focus on identifying and solving the root cause rather than just treating symptoms that will return.
