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!

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.

Recently Princeton Air did a routine maintenance check on our HVAC UNIT. The technician was Dominic McGinley. I must say Mr. McGinley was outstanding. After performing the maintenance and evaluation, he sat down with us and explained his findings in precise detail. He has also taken pictures of everything he found. Dominic was a pleasure with whom to interact. He was professional, friendly, and extremely knowledgeable. He explained everything in terms that we could definitely understand. He is one of the finest technicians that has ever performed preventative maintenance on our equipment. In my estimation he has all of attributes of a first rate Service Technician. Hopefully Princeton Air just what a valuable asset he is for the company. I certainly hope to interact with him many times in the future.
We recently used Princeton Air to install a new heater. They gave us lots of options, explained each one thoroughly, they arrived promptly on installation day and did a great job. The price was the lowest of three companies I contacted for estimates. Five stars!
Always professional and informative.
We just had our A/C serviced by tech Dominic McGinley who performed a thorough spring maintenance. Dominic was very friendly and courteous. He responded in detail to all my questions spending sufficient time with me.
We had valve and service line repairs from Germaine and Bradley, as well as a toilet replacement. They were great!
Julian found an issue with the ac and resolved it. Explained what the component does that needed replacement.

Emergency Service for All Types of Cooling Systems

From Belle Mead to Neshanic Station, Hillsborough Township’s diverse residential landscape features cooling systems that are just as varied throughout area homes.

At Princeton Air, our technicians are trained to diagnose and repair all major cooling system types throughout Hillsborough Township. 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 Hillsborough Township homes rely on central air conditioning for their primary cooling needs. Refrigerant issues, electrical faults, compressor failures, or frozen coils can cause system breakdowns that quickly spread discomfort throughout every room. Our technicians bring experience with all major central AC brands and configurations to restore whole-home cooling fast in Hillsborough Township, NJ.

Both heating and cooling depend on heat pumps, with summer cooling requiring precise refrigerant cycles and mechanical coordination. Component wear, electrical problems, or refrigerant loss can cause performance to decline rapidly in Hillsborough Township homes. Our Princeton Air technicians understand the complexities of heat pump systems and quickly pinpoint issues to restore efficient operation.

Additions, finished basements, and spaces without existing ductwork in Hillsborough Township homes increasingly rely on mini-split systems. 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 issues and restores the quiet, efficient cooling that makes these systems so popular throughout Somerset County.

Delivering the right temperature to each area of your Hillsborough v home is what zoned systems do best, but malfunctioning dampers, thermostats, or control panels can create hot spots or leave certain rooms without any cooling at all. Our technicians evaluate the complete system to pinpoint exactly where the breakdown is happening, then restore balanced comfort throughout your home.


Limit Future Issues When You Join the Princeton Air Comfort Club

Most cooling emergencies are the result of 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 efficiently and reliably 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 Hillsborough Township, NJ?

A cooling system breakdown during warm weather creates an emergency situation when your home can’t maintain comfortable temperatures. This covers units that refuse to start, systems running without producing cool air, strange noises or odors coming from the equipment, or AC that shuts off repeatedly before cooling your space properly. Somerset County’s muggy summer conditions make these failures particularly problematic since indoor temperatures climb rapidly. Delaying emergency AC repair in Hillsborough Township can lead to more extensive damage to your system.

How long does air conditioning replacement take in Edison, NJ?

Start by confirming your thermostat is set to “cool” with the temperature below your current room temperature, then check if your air filter is dirty or if a circuit breaker has tripped. These simple issues cause many AC problems in Hillsborough Township homes. Keep blinds closed on sunny windows and avoid running the oven, dryer, or other heat-producing appliances to help your home stay cooler. Turn the system off completely if you hear strange sounds or see ice on the unit, and leave it off until our technician can safely diagnose the problem.

Why is my AC running continuously without cooling the house?

When your AC runs constantly but doesn’t cool your Hillsborough Township home, the problem typically stems from low refrigerant, a dirty or frozen evaporator coil, compressor failure, or an undersized system struggling with New Jersey’s summer heat. Leaky ductwork can also cause this issue by allowing cooled air to escape before reaching your living areas. Our technicians will examine all these potential causes to pinpoint exactly what’s preventing your system from cooling effectively.

How does Hillsborough Township’s humidity affect air conditioning systems?

Somerset County’s humid summers create extra demands on AC systems because they must pull moisture out of the air while cooling your home. This dual workload stresses compressors and refrigerant components more than dry heat would, particularly in older equipment that’s already showing wear. The muggy conditions also make your home feel warmer than the actual temperature, leading many Hillsborough Township homeowners to lower their thermostats further and push their systems even harder.

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. If you’re looking at a repair bill that’s more than half the price of a new system, or if your AC is over 10-15 years old and keeps breaking down, replacement usually becomes the smarter choice. Our technicians in Hillsborough Township will assess your system honestly and explain both repair and replacement options so you can decide what works best for your situation and budget.
