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! 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 Does Air Conditioning Replacement Make Sense?

While some cooling problems can be solved with repairs, declining performance or unreliable operation in your Union Township home often signals that continuing to fix an aging system will create more frustration than relief.

Air conditioning systems throughout Union County have a finite lifespan, even with proper maintenance. Components naturally wear down over time. This causes efficiency to decline while breakdowns increase in frequency. Replacing your aging system brings back reliable performance and meets today’s efficiency standards.

Normal wear and tear means occasional air conditioning repairs in Union Township are expected. When you’re dealing with frequent service calls or a significant component breakdown, though, replacement typically offers superior long-term value and dependable performance.

When your air conditioning system in Union Township is aging or improperly sized, it struggles to deliver the same level of cooling performance. Unexplained increases in your utility bills often indicate your AC is losing efficiency. It’s working overtime to maintain comfort.

When your Union Township home develops hot spots, humidity problems, or experiences constant cycling, these issues typically indicate your system is no longer properly matched to your space. Balanced, steady comfort returns with a professionally-installed air conditioning system.



Take the First Step Toward Reliable Cooling in Union Township

The right system will bring back balance and protect your investment. For more than 50 years, Princeton Air has provided air conditioning replacement in Union Township, NJ, with care and integrity.

Frequently Asked Questions

How long does air conditioning replacement take in Union Township?

A typical air conditioning replacement in Union Township, NJ, takes one full day from start to finish. Homes with complex ductwork changes or electrical panel upgrades might need an extra day or two to complete everything properly. We’ll walk through the timeline with you upfront. No surprises about how long your home will be without cooling.

Do I need to replace my furnace when I replace my air conditioner in Union Township?

Your furnace doesn’t automatically need replacement when you get a new air conditioner in Union Township, NJ. A newer furnace in good working order can often pair perfectly with your new cooling system. When both units are getting older though, replacing them as a matched set typically delivers better energy efficiency and performance than mixing old with new.

How do I know what size AC system my Union Township home needs?

Your Union Township home’s cooling needs depend on much more than just square footage. Professional load calculations factor in your insulation levels, window types, ceiling height, and how air moves through your specific floor plan. Getting the sizing right prevents your new system from cycling on and off too frequently. This causes uneven temperatures and shortens equipment life.

What happens to my old equipment after air conditioning replacement in Union Township?

Your old air conditioning equipment gets removed and properly disposed of during our replacement process in Union Township, NJ. We handle refrigerant recovery according to EPA guidelines and recycle metal components through certified facilities. This responsible disposal approach protects the environment while clearing your property completely for the new installation.

Are permits required for air conditioning replacement in Union Township?

Yes, air conditioning replacement in Union Township typically requires permits and inspections to meet local building codes. Union Township follows New Jersey state regulations for HVAC installations, which include electrical and mechanical permits for most replacement projects. Princeton Air handles all permit applications and scheduling with local inspectors. Your new system meets both Union Township and state code requirements without any extra work on your part.
