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.

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! 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?

Not every cooling issue requires a full air conditioner replacement, but when performance declines or reliability becomes uncertain, continuing to repair an aging system can create more stress than comfort.

Even well-maintained air conditioning systems in Monroe Township have a lifespan. As components wear down, efficiency drops and breakdowns become more frequent. A new system restores dependable performance and modern efficiency standards.

Occasional air conditioning repairs in Monroe Township are normal. But if you’re facing repeated service calls or a major component failure, replacement often provides better long-term value and reliability.

An aging or improperly sized air conditioning system in Monroe Township works harder to produce the same cooling. If your utility costs are climbing without explanation, your AC may be losing efficiency.

Hot spots, humidity issues, or constant cycling in your Monroe Township home are signs your system may no longer be properly matched. A professionally-installed air conditioning system restores balanced, steady comfort.



Take the First Step Toward Reliable Cooling in Monroe Township

If your air conditioner is no longer delivering the steady, reliable comfort your home deserves, it’s time for a thoughtful replacement.

The right system will bring back balance and protect your investment. For more than 50 years, Princeton Air has provided air conditioning replacement in Monroe Township with care and integrity. We’re here to make air conditioning replacement in Monroe Township clear, smooth, and respectful from the first call to final installation.

Frequently Asked Questions

How long does air conditioning replacement take in Monroe Township?

Most air conditioning replacements in Monroe Township can be completed in a single day. Larger homes, ductwork modifications, or electrical upgrades may extend the timeline slightly. Before work begins, we provide a clear schedule so you know exactly what to expect.

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

Not always. If your furnace is newer and in good condition, it may be compatible with your air conditioning replacement in Monroe Township. However, if both systems are aging, replacing them together can improve efficiency. We evaluate your entire setup and provide honest recommendations.

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

Proper sizing for air conditioning replacement in Monroe Township requires more than square footage alone. We perform detailed load calculations that account for insulation, windows, layout, and airflow. An accurately sized system prevents short cycling, uneven cooling, and premature wear.

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

We safely remove and dispose of your existing system as part of every air conditioning replacement in Monroe Township. Refrigerant is handled responsibly and materials are processed properly to reduce environmental impact.

Are permits required for air conditioning replacement in Monroe Township?

Yes. Permits and inspections are required for air conditioning replacement in Monroe Township in most cases. Princeton Air manages the entire permit process and ensures your installation meets local and New Jersey code requirements.
