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.

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 Princeton Air complete an AC repair in Morristown?

Most AC repairs in Morristown can be finished during one service call since our technicians carry common parts and diagnostic tools with them. We prioritize fast response times when Morris County temperatures spike and cooling systems fail completely. For total breakdowns that leave families without air conditioning, we offer around-the-clock emergency service. We know how quickly a home becomes uncomfortable during New Jersey’s humid summers.

Does Princeton Air service all AC brands in Morristown?

Absolutely. Princeton Air technicians work on all major residential AC brands and system types throughout Morristown and Morris County. We train our team to understand how cooling systems function as a whole rather than focusing on just one manufacturer. This leads to better diagnostics and more reliable air conditioning repair in Morristown regardless of what brand is installed in your home.

How do I know whether to repair or replace my air conditioner in Morristown?

The decision comes down to your system’s age, the scope of the problem, and whether the repair cost makes financial sense. For AC units in Morristown that are under 10 years old with isolated issues, repair typically offers the best value. We look at your equipment’s condition, efficiency level, and service history to give you an honest assessment. You’ll get a straight answer about which option truly serves your home best. No pressure either way.

What’s the most effective way to prevent AC problems in Morristown?

Regular professional maintenance prevents most AC problems before they start. During annual service visits, technicians clean dirty coils, verify refrigerant levels, inspect electrical connections, and spot worn components that could fail during peak cooling season. Homeowners throughout Morristown find that consistent yearly care through programs like Princeton Air’s Comfort Club keeps their systems running reliably. It protects their investment over time.

What should I do if my AC keeps breaking down even after repairs?

The same problems keep coming back? There’s usually an underlying cause like improper system sizing, persistent airflow restrictions, or equipment that’s simply worn out from years of service. Instead of fixing the same issue repeatedly, we investigate what’s actually causing the pattern of failures. Our approach to air conditioning repair in Morristown focuses on solving the root problem so you get lasting results. Not temporary fixes that leave you calling for service again next month.
