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

Many Union Township homes rely on heat pumps as versatile comfort systems that provide both heating and cooling throughout the year.

Frequently Asked Questions

What qualifies as an emergency air conditioning repair in Union Township?

You need emergency AC repair in Union Township when your system completely shuts down or your home reaches unsafe temperatures during hot weather. Problems that demand immediate attention include units that blow warm air instead of cool, won’t start up, leak refrigerant, or keep cycling on and off. Union Township’s humid summers can push indoor temperatures to dangerous levels within hours when cooling fails. Quick professional response is critical for both comfort and preventing further damage to your equipment.

What should I do if my air conditioner suddenly stops working in Union Township?

Start by checking your thermostat settings, air filter condition, and electrical panel for tripped breakers. A dirty filter or flipped breaker can shut down your system completely or cause it to blow warm air. Simple fixes first. When these checks don’t solve the problem, call Princeton Air for emergency AC repair in Union Township, NJ, rather than attempting repairs yourself. DIY troubleshooting on cooling equipment often creates bigger problems and potential safety hazards.

Why is my air conditioner running but not cooling my Union Township home?

An air conditioner that runs without cooling typically has one of several underlying problems affecting its ability to remove heat from your home. Low refrigerant from leaks, ice buildup on indoor coils, blocked air filters, faulty thermostats, or failing compressors can all cause this frustrating situation. Union Township’s humid summer conditions make these issues particularly noticeable since your system has to work harder to pull moisture from the air while cooling. Professional diagnosis pinpoints which component is preventing your AC from doing its job so the right repair can restore cool air throughout your home.

Can extreme heat cause my AC system to fail in Union Township?

Yes, extreme heat can definitely cause AC failures, particularly in older systems or units that haven’t received proper upkeep. Your air conditioner runs almost continuously for days during Union Township heat waves. This puts stress on components like compressors, fan motors, and electrical connections that might already be wearing out. Systems with dirty coils, low refrigerant, or restricted airflow struggle even more during heat waves and often break down when you need them most.

Do older air conditioning systems in Union Township experience more emergency breakdowns?

Yes, aging air conditioning systems in Union Township do break down more frequently as key components reach the end of their useful life. After 10-15 years of operation, compressors start working harder to maintain cooling capacity, electrical connections can loosen from repeated heating and cooling cycles, and refrigerant lines develop small leaks that reduce system efficiency. Union Township’s humid summers put additional stress on older equipment since these systems must remove both heat and moisture from your home’s air. Repair costs add up quickly. When this happens on an aging system, replacement often becomes the more practical choice.
