Princeton Air Conditioning replaced my 25 year old central air conditioner. The sales person was very knowledgeable, made sure I was getting the correct size unit, explained the available options and got a quote out very quickly.

MOST RECENT June 2026:
Weltman has been purchased by Princeton Air. They have been really great. A seamless transition on the customer side. Eric was just here to put in a new anti-scaling system and a pressure relief valve for the house. Very happy!

UPDATE:
Now in our home for almost 8 years and Weltman has never disappointed! Chris L came today and was completely professional and quick for our yearly inspection of our furnace before the cold winter! Itโ€™s great to know they keep great notes and, almost, know more about our system than we do!

Weltman will always make it right if something is wrong. They will also get to you ASAP! We have been customers since we bought our home 3 years ago and have been completely satisfied!
Teck was knowledgeable and courteous
The technician Alfredo is great
I was recommended Princeton Air by a friend and Iโ€™m very happy that I was. I had a hvac and furnace system that was 25 years old and in dire need of replacement.
Chris from the company came out very promptly and did a full review, taking the time to take me through the different options. From there we reached an agreement and within one week the team came out and did a full dual zone system replacement.
I was blown away by the professionalism and indeed sheer hard work of the installation team. They arrived at 08.30am and finished at 8.30pm working tirelessly to complete the job in one day. A huge thank you to Princeton air, Chris and the install team -Jorge Vizueta, John Jaramillo, Juan Torres and Jhonny Anacona for a really cool air conditioning experience. Thank you!
The repair man, Dominic came out this morning to inspect our AC system. He was extremely knowledgeable, incredibly kind, and explained things very well. I work in construction and can tell you that Dominic is one of the best Iโ€™ve seen in years. Princeton air is very lucky to have him as an employee as he is SUCH AN ASSET to your company.

I also want to give a special thanks to Leah the customer service representative I spoke to. Also extremely kind and helpful. I have had the worst two weeks of my life and two strangers taking the time to kind made my heart smile. Thanks again Leah and Dominic.
Norman was great!!! He has come before. His advice and work were great!!!! Unfortunately Princeton Air, formerly a family run business, has been bought by a large corporate group, and we have chosen not to use them any longer
The technician was thorough, knowledgeable and professional. He also called for an ETA and was punctual.
I wanted to say a BIG Thank you to Princeton Air and Jesus C for coming to our rescue when AC in our house wasnโ€™t working (despite it working fine 3 weeks ago). My daughter and her friends arrived on Friday afternoon for a girls weekend. Even though the compressor unit outside was running, no air was coming through the vents inside the house. After talking her through a few things over the phone (none of which resolved the issue), I called Princeton Air.
Despite it being already 5pm on Friday, they dispatched a technician who arrived within an hour. Jesus C called me several times to keep me updated about the repair. Within 45 min, the air was blowing COLD!!
I highly recommend this company. I am beyond grateful for the prompt and professional service we received.
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.
Just to let you know everything here is fine. Norman was wonderful!! Helpful and very friendly. Thank you Norman and thank you Princeton Air.
Great service , Ryan was fantastic
We recently had a new AC unit installed by Princeton Air and had a great experience from start to finish. The installation went smoothly, the team was professional, knowledgeable, and respectful of our home, and we are very satisfied with the quality of the work.
We did have one minor issue after the installation, but Dominic McGinley responded quickly and took care of it right away. His prompt service and commitment to making sure everything was working properly really stood out.
Overall, weโ€™re very happy with Princeton Air and would highly recommend them to anyone looking for HVAC services.
Excellent technician with thorough explanation of the problem
Dillion was very pleasant ,He informed me what he was going to do what Needed to be done and afterwards Everything that was completed
Jorhe arrived and listened to what I needed in this routine service call and when he finished all my questions were answered & for the 1st time Iโ€™m able to understand the function and area each thermostat controls!
Cheers for you Jorhe!

happy mother with two happy children

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.
