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!
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!

Emergency Plumbing Services in Princeton

From a single failing fixture to a full-scale plumbing crisis, every plumbing emergency feels unique when it’s happening in your home.

Our emergency plumbers in Princeton are trained and prepared for the most demanding situations homeowners face. Princeton Air is equipped to handle it all. Here’s what we handle.

Hidden leaks behind walls, beneath floors, or at critical connection points often remain undetected just long enough to cause substantial damage before becoming apparent. Using professional leak detection methods, Princeton Air pinpoints the exact source of water leaks in Princeton homes, shuts off the affected supply line, and executes repairs that completely eliminate the problem.

Overflowing toilets in Princeton homes create an immediate mess while often pointing to deeper drain line issues. Whether it’s a stubborn blockage, damaged flapper, or broader drain line problem, Princeton Air identifies the root cause and restores proper function before water damage spreads to your bathroom floor or subfloor.

A sewer line backup in Princeton ranks among the most disruptive and urgent plumbing emergencies homeowners face. Health risks become immediate when sewage reverses course and enters your home through drains or toilets, creating a serious mess that demands professional attention. Princeton Air’s team uses specialized equipment to identify and clear blockages, from tree root intrusions to collapsed pipe sections, restoring safe, fully functional drainage as quickly as possible.

A burst pipe sends water flooding into your Princeton home at a devastating rate. Thousands of dollars in damage can accumulate within just minutes. Winter freezes, internal corrosion, or sudden pressure spikes often trigger these failures, demanding immediate professional response. Our plumbers quickly isolate the damaged section, halt the water flow, and execute a permanent repair or replacement that prevents future recurrence of the problem.

Many Princeton homes rely on sump pumps to prevent basement flooding, especially given the area’s terrain and frequent storm activity. A sump pump failure, whether from mechanical breakdown, power loss, or a malfunctioning float switch, creates an immediate flood risk for your basement. Princeton Air provides rapid sump pump repair and replacement in Princeton, NJ to safeguard your basement before severe weather strikes again.

Your water heater suddenly fails in Princeton, your household loses hot water service immediately. Tank ruptures or serious internal failures can flood your utility room or basement. Our plumbers thoroughly evaluate the unit, repairing what’s salvageable while providing honest guidance when replacement makes more sense for the long term. We work quickly either way to restore reliable hot water service to your Princeton home.

What to Do During a Plumbing Emergency

Your first few minutes during a plumbing emergency in Princeton can make all the difference. The right immediate actions help minimize damage while our team rushes to your location.

For Princeton homeowners facing an active plumbing emergency, these steps will help you protect your property until help arrives.

Cutting off the water supply should be your immediate first step. For problems isolated to a specific toilet, sink, or appliance, locate the shutoff valve directly behind or beneath that fixture and turn it off. When the issue affects multiple areas or you can’t identify the source, head directly to your home’s main shutoff valve. Stopping water flow immediately is the most effective action you can take to prevent further damage to your Princeton property.

Electricity and water create a dangerous combination in Princeton homes. Keep clear if standing water appears near outlets, appliances, or your electrical panel, and consider shutting off power to the affected zone from your breaker box. Never attempt to use or move electrical devices that have been exposed to water. Safety always comes first.

After taking those initial protective steps, contact Princeton Air for emergency plumbing service. Getting your call quickly means we can dispatch a plumber faster and begin working toward a solution right away. While you wait for our arrival, our team provides guidance over the phone. You won’t have to navigate the situation by yourself.

Furniture, rugs, electronics, and documents should be moved away from the affected area immediately to protect them from water damage. Buckets and towels can help contain the moisture and slow its spread throughout your home. While these steps won’t permanently solve the problem, they can significantly limit the damage that occurs before our plumbers arrive to complete repairs.

Frequently Asked Questions

How do I know if my plumbing problem qualifies as an emergency in Princeton?

Active water leaks, flooding, sewage backups, or any situation threatening your property counts as a plumbing emergency. You’re also looking at an urgent situation if you’ve lost all water service, your sump pump fails during heavy rain, or waste water starts coming up through your drains. Princeton’s older homes can be particularly vulnerable to sudden pipe failures, especially during winter freezes or after heavy storms that stress aging plumbing systems. Trust your instincts. If the situation feels serious or could get worse quickly, it probably qualifies as an emergency.

Can a plumbing emergency lead to long-term damage if not addressed quickly?

Yes, water damage spreads quickly and gets worse by the hour. Within just one to two days, water can weaken subfloors, damage wooden framing, ruin insulation, and create the perfect conditions for mold to start growing throughout your Princeton home. The costs multiply rapidly when emergency plumbing repairs get delayed, making immediate action the smart financial choice.

What should I do if sewage is backing up into my home?

Turn off all water usage throughout your home right away and contact Princeton Air for emergency plumbing immediately. Don’t pour drain cleaners down the affected drains or try flushing toilets repeatedly. These actions often push the backup deeper into your system or cause additional pipe damage. Professional equipment is needed to safely clear sewer blockages and get your drainage working properly again.

Are certain plumbing emergencies more common during specific times of year in Princeton?

Absolutely. Princeton’s winter freezes create the highest risk for burst pipes, especially in older homes throughout neighborhoods like Jugtown and Western Section where insulation may be inadequate. Heavy spring and fall storms can overwhelm sump pumps or cause sewer line backups when drainage systems get stressed. Summer’s heat and increased water usage put extra strain on water heaters, making appliance failures more likely during the hottest months.

Will Princeton Air complete the full repair in one visit?

We carry the parts and tools needed for most emergency plumbing repairs right on our trucks, so we can usually finish the job completely during your first visit. Sometimes we can’t complete everything the same day. Maybe we need a special part or there’s an unusual situation. We’ll explain exactly what’s happening and what comes next. Our focus is always on permanent fixes rather than temporary patches that might fail again later.
