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.

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.

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.

From sudden shutdowns to gradual performance decline that’s reached the breaking point, our South Brunswick technicians repair central AC systems, heat pumps, and mini-splits quickly.

Cooling capacity drops right along with refrigerant levels in South Brunswick systems. Our technicians locate and repair leaks, then recharge your system to the correct specification.

Control system breakdowns in South Brunswick homes can shut down cooling completely. Even when the AC equipment itself is working perfectly. Communication failures between your thermostat and the unit create this frustrating problem, and we diagnose and resolve these control issues quickly.

Electrical faults and compressor failures bring cooling systems to an immediate halt in South Brunswick homes. Our technicians safely diagnose these critical issues and complete repairs to restore full operation.

Emergency Service for All Types of Cooling Systems

From Dayton’s established neighborhoods to newer developments in Kendall Park, South Brunswick homes feature a wide range of cooling systems that match this residential diversity.

At Princeton Air, our technicians are trained to diagnose and repair all major cooling system types throughout South Brunswick. When your system stops working, you can trust our team to identify the issue quickly and restore emergency cooling service with the right solution for your equipment.

Most South Brunswick homes rely on central AC as their primary cooling solution. A refrigerant issue, electrical fault, compressor failure, or frozen coil can quickly spread discomfort throughout the entire house when these systems fail. With experience across all major central AC brands and configurations, our technicians work quickly to restore whole-home cooling in South Brunswick.

Both heating and cooling depend on heat pumps. Summer cooling performance ties directly to precise refrigerant cycles and mechanical components working in harmony. Component wear, electrical faults, or refrigerant loss can cause performance to decline rapidly in South Brunswick homes. Our technicians understand heat pump operation and can quickly identify and resolve these issues to restore cooling.

Mini-splits have become increasingly popular cooling solutions in additions, finished basements, and spaces without existing ductwork throughout South Brunswick. Depending on the configuration, a failed indoor air handler or outdoor unit can impact just one room or compromise the entire system. Our team accurately diagnoses ductless system issues in South Brunswick and restores the quiet cooling performance these units are designed to deliver.

Zoned systems deliver precise temperature control to different areas of your South Brunswick home. But malfunctioning dampers, thermostats, or control panels create frustrating hot spots and rooms that refuse to cool properly. Our technicians evaluate the complete system to pinpoint exactly where the breakdown is happening, then restore balanced comfort throughout every room in your home.


Limit Future Issues When You Join the Princeton Air Comfort Club

Most cooling emergencies result from small issues that went undetected until the system finally gave out.

The Princeton Air Comfort Club is our annual maintenance program designed to catch those issues before they become emergencies. Members receive scheduled seasonal inspections and tune-ups that keep cooling systems running well through the hottest months.

Regular professional maintenance improves performance, extends equipment life, and significantly reduces the likelihood of a breakdown on the worst possible day. For homeowners who want fewer emergencies and lower long-term costs, Comfort Club membership is a smart investment.

Frequently Asked Questions

What counts as an AC emergency in South Brunswick, NJ?

A cooling system failure becomes an emergency when your South Brunswick home can’t maintain comfortable temperatures and indoor heat starts building up rapidly. This covers units that refuse to start, systems running without producing cool air, strange noises or odors coming from the equipment, or units that shut down before reaching your thermostat setting. South Brunswick’s muggy summer weather makes these breakdowns particularly problematic. The combination of heat and humidity can make your home uncomfortable within hours, and delaying repairs often leads to more extensive damage.

What steps should I take while waiting for a technician?

Start by confirming your thermostat is set to “cool” with the target temperature below your current room temperature. Then check if a dirty air filter or tripped circuit breaker might be causing the problem. Pull blinds and curtains closed on windows facing the sun to reduce heat buildup in your South Brunswick home. Skip using the oven, dryer, or other heat-producing appliances until your AC is working again. Turn the system off completely if you hear strange sounds or see ice forming anywhere on the unit, and keep it off until our technician can safely diagnose the issue.

Why is my AC running continuously without cooling the house?

Your AC runs constantly but doesn’t cool your South Brunswick home effectively. The problem typically stems from low refrigerant, a dirty or frozen evaporator coil, compressor failure, or an undersized system struggling during peak heat. Leaky ductwork can also cause this issue by allowing cooled air to escape before reaching your living areas. Our technicians will perform a complete system inspection to pinpoint the exact problem and get your cooling back on track.

How does South Brunswick’s humidity affect air conditioning systems?

High humidity levels in South Brunswick force your AC to pull moisture from the air while cooling. This creates a double workload that stresses compressors and refrigerant components. This extra strain accelerates wear on aging parts and makes your home feel warmer than the actual temperature reading. The air feels sticky and uncomfortable. Homeowners naturally push their systems harder, which compounds the stress on equipment that’s already working overtime in New Jersey’s muggy summer conditions.

Is it worth repairing an older air conditioner, or should I replace it?

Several factors determine whether repair or replacement makes more sense: your system’s age, what’s actually broken, and how much the fix costs compared to what the unit is worth. Generally, if you’re looking at a repair bill that’s more than half the price of a new system, or if your unit is over 10-15 years old and keeps breaking down, replacement often becomes the smarter choice. Our South Brunswick technicians will assess your system honestly and explain both repair and replacement options without any pressure. You can choose what works best for your situation.
