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.
They are a great company, hvac techs where totally professional,
Ryan G is a knowledgeable, professional and has great customer service.
Martique was 5+! Extremely knowledgeable and thorough. I do have a significant concern about one of the inspection findings related to the evaporator coils. Will address directly with the company.

Great service and follow up. Honest answers
Dominic was very professional and installed my new Nest Thermostat in. He showed me some features and mage sure I had the app set up on my I- Phone. Dominic forgot to put the door back on my furnace but returned and put it securely back on.
I was very happy with the central air conditioning system Princeton Air installed for me. They were very prompt in getting a quote to me, were very competitive and did an excellent job with the installation. I plan on using them for all maintenance on the unit and highly recommend them.
I appreciate how responsive Princeton Air is. Tom did all he could to fix our system.
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! 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 you respond to an AC repair call in Union Township?

We respond quickly to AC repair calls in Union Township, particularly during hot weather and your comfort is at risk. Our local presence throughout Union County means we can reach your home faster than companies traveling from distant areas. For complete system failures, our 24/7 emergency service gets your cooling restored safely and efficiently, no matter the time of day.

How do I know if I need a repair or a full replacement?

Most air conditioning problems in Union Township can be fixed without replacing the entire system. We look at your unit’s age, current condition, and how efficiently it’s running to determine whether AC repair in Union Township makes financial sense or if replacement would serve you better long-term. A quality repair often restores years of reliable performance. But we’ll tell you straight if your system has reached the point where continued repairs aren’t worth the investment. Our recommendations are based on what’s actually best for your situation, not what generates the biggest sale.

Do you repair all brands of air conditioners in Union Township?

Absolutely. Our technicians work on all the major residential air conditioning brands you’ll find in Union Township homes. We approach every repair by looking at how your complete system functions together. This lets us fix the actual problem causing your cooling issues rather than just treating symptoms.

What if my AC keeps breaking down in Union Township?

Repeated breakdowns usually point to a deeper problem with your Union Township system: wrong sizing for your home, blocked airflow, electrical issues, or worn-out parts that keep failing. Instead of patching the same problems over and over, we look at your entire cooling system to find what’s really causing the trouble. We focus on permanent fixes that stop the cycle of callbacks and get your AC running reliably again.

How can I prevent future AC problems in Union Township?

Regular maintenance visits catch small problems before they turn into expensive breakdowns that leave you without cooling during Union Township’s humid summers. During these tune-ups, we clean your system, check refrigerant levels, and spot worn parts that could fail soon. Our Comfort Club program provides Union Township homeowners with scheduled maintenance visits and priority service for repairs.
