Helped with an electrical issue. Fair and affordable.
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!
We have used Princeton Air twice for our HVAC and once for plumbing. Each time, the technician was courteous and professional, and the issues were resolved. We recommend Princeton Air!
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.
Wilver did a great job replacing my toilet. He was respectful and quickly diagnosed the problem. He came back with a beautiful Glacier toilet which he quickly installed. I highly recommend him for any toilet job!

I just had Alberto fix my furnace as my house was 60 degrees this morning…he diagnosed the issue quickly, got the part and installed it in record time! He was my angel of the hour and I will never forget all he did for me today. I highly recommend him if you have a heating issue.

I had Brian replace my electrical box and he did a fabulous job. I highly recommend him if u need it done.

Jose just fixed my AC problem as it was not coming on and a heat wave is coming this week! He was extremely knowledgeable, went outside to check everything (thorough) and got my cool air on expeditiously! He has a wonderful demeanor and a pleasure to work with. I highly recommend him for any of your AC needs this summer. Ask for him…you'll be happy you did!
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!
Replaced central a/c system. Team arrived early morning and explained the process thoroughly, asked if we had any questions, then proceeded with the work. The job was completed quickly, a couple of little glitches were resolved with no impact. Only concern I had, we did not receive a call the day before confirming installation and time. All in all I would still recommend Princeton Air.
Great job. Worked efficiently. Work area clean

happy mother with two happy children

AC systems involve a lot of moving parts. A fast fix requires a team that can handle the full range of problems a system can develop, not just the most common ones.

Our technicians handle the full spectrum of AC system components, from mechanical failures to electrical faults and refrigerant issues. This broad training means we can track down problems that hide in complex interactions between systems. We deliver lasting emergency AC repair in Morristown that addresses the root cause.

From sudden system shutdowns to gradual performance decline that’s reached a breaking point, our technicians provide fast repairs for central AC systems, heat pumps, and mini-splits throughout Morristown.

Cooling capacity drops right along with refrigerant levels in Morristown’s humid climate. Our technicians locate and repair leaks, then recharge your system to the correct specification.

Control system failures can halt cooling in Morristown homes even when the AC equipment itself remains perfectly functional. Our technicians quickly diagnose and resolve these communication breakdowns between thermostats and cooling units.

Compressors fail or electrical faults occur in Morristown homes. Cooling systems can shut down without warning. Our technicians safely diagnose these critical issues and complete repairs to restore full operation.

Your cooling system can’t be saved sometimes. Our technicians in Morristown will give you straight answers and guide you through replacement choices that work for your home and schedule. No high-pressure tactics. No confusing sales pitches.

Emergency Service for All Types of Cooling Systems

From historic homes in Downtown Morristown to newer developments in Spring Valley, the cooling systems throughout area residences are just as diverse as the neighborhoods themselves.

At Princeton Air, our technicians are trained to diagnose and repair all major cooling system types throughout Morristown. When your system stops working, you can trust our team to identify the issue quickly and restore emergency cooling service with the right solution for your equipment.

Most Morristown homes rely on central AC as their primary cooling solution. Refrigerant issues, electrical faults, compressor failures, or frozen coils can cause system breakdowns that quickly turn the entire house uncomfortable. Our technicians bring experience with all major central AC brands and configurations to restore whole-home cooling in Morristown efficiently.

Heat pumps provide year-round comfort for Morristown homeowners, with summer cooling that depends on precise refrigerant cycles and mechanical components working together. Component wear, electrical faults, or refrigerant loss can disrupt this balance and cause performance to decline rapidly. Our Princeton Air technicians bring deep knowledge of heat pump systems to quickly diagnose issues and restore efficient operation.

Ductless mini-split systems have gained popularity throughout Morristown, particularly for home additions, finished basements, and rooms where traditional ductwork isn’t practical. A failed indoor air handler or outdoor unit can impact just one zone or compromise the entire system, depending on how it’s configured. Our technicians quickly identify ductless system problems in Morristown. They restore the whisper-quiet, energy-efficient cooling performance these units deliver.

Zoned systems deliver precise temperature control to different areas of your Morristown home, but malfunctioning dampers, thermostats, or control panels can create hot spots or rooms that refuse to cool properly. Our technicians evaluate the complete system to pinpoint exactly where the breakdown is happening. Then they restore balanced comfort throughout every zone of your home.


Limit Future Issues When You Join the Princeton Air Comfort Club

Most cooling emergencies are the result of small issues that went undetected until the system finally gave out.

The Princeton Air Comfort Club is our annual maintenance program designed to catch those issues before they become emergencies. Members receive scheduled seasonal inspections and tune-ups that keep cooling systems running efficiently and reliably through the hottest months.

Regular professional maintenance improves performance, extends equipment life, and significantly reduces the likelihood of a breakdown on the worst possible day. For homeowners who want fewer emergencies and lower long-term costs, Comfort Club membership is a smart investment.

Frequently Asked Questions

What counts as an AC emergency in Morristown, NJ?

A cooling system that stops working creates an emergency situation, particularly during hot weather. This covers units that refuse to start, systems running without producing cool air, strange noises or odors coming from the equipment, or air conditioners that shut off repeatedly before cooling your home properly. Morristown’s humid summer conditions make these failures especially problematic. The combination of heat and moisture can make your home uncomfortable within hours, and waiting too long often allows minor issues to develop into more serious problems requiring emergency AC repair in Morristown.

What steps should I take while waiting for a technician?

Start by confirming your thermostat is set to “cool” with the temperature below your current room temperature, then check if a dirty air filter or tripped circuit breaker might be causing the problem. Pull down blinds on sunny windows and skip using the oven or dryer to keep heat from building up in your Morristown home while you wait. Turn the system off completely if you hear strange sounds or see ice on the unit. Running it could cause more damage before your technician arrives.

Why is my AC running continuously without cooling the house?

Your AC runs constantly but doesn’t cool your Morristown home for several reasons. The problem typically stems from low refrigerant, a dirty or frozen evaporator coil, compressor failure, or an undersized system struggling with New Jersey’s summer heat and humidity. Leaky ductwork can also cause this issue by allowing conditioned air to escape before reaching your living areas. Our technicians will perform a complete system inspection to pinpoint the exact problem and get your cooling back on track.

How does Morristown’s humidity affect air conditioning systems?

High humidity in Morristown creates a double burden for air conditioning systems. They have to pull moisture out of the air while also cooling it down. This extra work puts additional stress on your compressor and refrigerant components, which can lead to faster wear and more frequent need for AC repair in Morristown. The humid air also makes your home feel warmer than the actual temperature, so many homeowners push their systems harder trying to get comfortable, which only adds to the strain.

Is it worth repairing an older air conditioner, or should I replace it?

Several factors determine whether repair or replacement makes more sense: your system’s age, what’s actually broken, and how much the fix will cost compared to what the unit is worth. Generally, if you’re looking at a repair bill that’s more than half what a new system costs, or if your AC is over 10-15 years old and keeps breaking down, replacement often becomes the smarter choice. In Morristown’s humid climate, older systems also work harder and less efficiently. This can drive up your energy costs even when they’re running properly.
