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 did a great job. Nelson was very knowledgeable and professional.
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! It’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 I’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 I’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 wasn’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, we’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 I’m able to understand the function and area each thermostat controls!
Cheers for you Jorhe!

When Is It Time to Replace Your Air Conditioner?

While some problems can be fixed with repairs, declining reliability and performance often make continued maintenance of an aging system more disruptive than helpful for South Brunswick homeowners.

Frequently Asked Questions

Do I need to replace my furnace at the same time?

Your furnace can often stay if it’s relatively new and works well with the new AC unit. Both the furnace and air conditioner are getting older? Replacing them as a pair usually gives you better overall performance and energy savings. We’ll check your current furnace during the AC replacement evaluation in South Brunswick and explain whether keeping it makes sense for your specific situation.

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

A typical air conditioning replacement in South Brunswick takes one full day from start to finish. Homes that need electrical upgrades, ductwork modifications, or additional system components may require an extra day or two. You’ll know the exact timeline upfront based on what your specific installation requires.u003cbru003e

How is the right system size determined?

Proper system sizing requires detailed load calculations that go well beyond your home’s square footage. We measure insulation levels, window placement, ceiling height, and airflow patterns throughout your South Brunswick home to determine the exact cooling capacity needed. Getting this calculation right means every room stays comfortable without the system working harder than necessary.

What happens to my old air conditioner?

Your old air conditioner gets removed and disposed of following all environmental regulations, with special attention to proper refrigerant recovery and handling. We take care of the entire removal process during your air conditioning replacement in South Brunswick, leaving your property clean and handling every component according to New Jersey’s disposal requirements. The whole process stays compliant with local and federal guidelines without any extra steps needed from you.
