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. Will D came out and sure enough, confirmed there was a problem, explained what exactly was happening, why it was happening and how to check that it was working correctly. His demeanor was pleasant, he was professional and seemed to be quite knowledge!
Great service. Domenic was so helpful and explained everything done.
Jermaine Richmond was very knowledgeable and explained my plumbing issue throughly. Thank you.
Pretty micron air was quick to fix my sewer
Friendly and efficient. Quick response service
Eric did a fantastic job
Installation of water heater hvac and furnace – very professional and process oriented –
The technician who came was Jonathan Redondo. He was very knowledgeable and did an excellent job! I would highly recommend him .
Christian and Mike were professional, thorough, patient, and kind throughout my heating boiler installation.
Always excellent service with McAllister.
Robert came to check my 2 carbon monoxide detectors, which were very old. I decided to have him go ahead and replace them with smoke detector/ carbon monoxide combination units. He was very polite and efficient .
Jihmy and Asterson did an outstanding job and were extremely professional during a recent installation of a mini split and air handler. They communicated well, kept the house clean and did the job with a level of professionalism and expertise that was refreshing.
Good job
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. Iโ€™m so happy with their staff and with Maurice- heโ€™s a gem!
Thank you!
The young man who came out to fulfill our annual service contract was extremely professional and was very thorough. Although he told us we needed a new ac unit I felt confident that he knew what he was talking about and took the right amount of time in order to make his recommendation. I want him back every year. Unfortunately I forgot his name because Iโ€™m old.

He then had Ricky call us with replacement ac unit recommendations. He was just as professional. He then took the time to visit our condo, take measurements himself and then made recommendations on what size unit to purchase. I really feel he saved us money. He was amazing.

We then were contacted by a gentleman named Steve who was a manager in the service and installation department. Itโ€™s hard to believe but he was just as good as the first two representatives and was an absolute pleasure to work with. He was a true professional and a real asset to your organization. I will always use your company if I can work with this team. Keep up the great work. Thanks for allowing me to spend $8,000.its hard to believe I didnโ€™t even get other quotes because I was so happy with your team.

Frequently Asked Questions

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

The majority of AC repairs in South Brunswick can be finished during one service call. Our technicians arrive prepared with common parts and diagnostic tools. We prioritize fast response times during New Jersey summers, knowing that a broken cooling system creates real discomfort quickly. For complete system failures, we offer around-the-clock emergency service. Some situations simply can’t wait until regular business hours. Our scheduling reflects the reality that air conditioning problems need prompt attention, especially during peak cooling season.

Does Princeton Air service all AC brands in South Brunswick?

Absolutely. Princeton Air technicians work on all major residential AC brands and system types throughout South Brunswick. From older units in established neighborhoods to newer high-efficiency models in developments. We train our team to understand how cooling systems function as complete units rather than focusing on just one manufacturer. This leads to better problem-solving and more reliable air conditioning repair in South Brunswick regardless of what brand is on your equipment.

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

The decision depends on your system’s age, the scope of the problem, and how much the repair costs compared to what your equipment is worth. For air conditioning repair in South Brunswick, we look at several factors: how old your unit is, its overall condition, current efficiency levels, and whether you’ve needed multiple repairs recently. A repair makes financial sense and will give you reliable cooling? That’s what we’ll recommend. If your system has reached the point where replacement is the smarter investment, we’ll walk you through the reasoning so you can make the best choice for your home.

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

Regular professional maintenance makes the biggest difference in preventing AC breakdowns. During these visits, technicians clean dirty coils, verify refrigerant levels, and inspect electrical connections. They spot problems before they turn into expensive failures that leave you without cooling on hot South Brunswick days. Consistent annual care keeps your system running reliably and protects your investment over time.

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

The same AC problems keep coming back? It’s usually a sign that the real issue runs deeper than individual broken parts. Common underlying causes include an oversized or undersized system, persistent airflow restrictions, or an aging unit that’s simply wearing out faster than repairs can keep up. Instead of continuing to fix symptoms as they pop up, we evaluate the whole picture to find what’s actually causing the repeated breakdowns. This approach leads to air conditioning repair in South Brunswick that actually solves the problem instead of creating an endless loop of service visits.
