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. They were very competitive on price and did an excellent job installing the unit. I am planning on having them provide all maintenance on the unit. I highly recommend Princeton Air Conditioning.

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!

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.
