As a second generation McAllister, now, Princeton customer in Atlantic County, I am pleased to report another successful system installation. This year it is a state-of-the-art Combi water heater and HVAC installation at the seashore. Scheduling occurred with "military precision." The bevy of workers and equipment arrived on time — all friendly and informative. By the second day all done, manual provided & questions answered. Always a good crew to have onsite. Company was also very helpful in scheduling my A/C system maintenance at the same time as all the other work beating the start of the summer season.
Service man Ryan is always very professional and thorough and takes the time to explain whatโ€™s going on with our heating and air-conditioning system.
I waited all day three times for the repairman. I am going to change my service provider.
Technician was very good.
Prompt, polite, informative, professional, thorough
Ryan G arrived promptly to my home to see why my air conditioning unit wasn't working. He clearly explained upfront the charges for diagnosing the problem. He quickly discovered the source of the issue and showed me pictures of the clogged a/c pipe and explained the work he would be doing. After the work was completed, he showed me how much debris he pumped out of the pipe and explained the charges which were very reasonable. I was thoroughly happy with the service that Ryan G provided. His descriptions and instructions were very clear. I would highly recommend Ryan G. & Princeton Air to all !
Our tech Dominic was Great!!
Princeton Air did a great job installing my new Carrier Furnace and A/C system. Devin and Woody were really polite and professional. Great experience and thorough cleanup. Also, Joe was a really professional electrician, and a really nice guy.
Iโ€™m very happy with my new system.
Thank you Princeton Air.
Latrell and Norman two very hard workers ran into situations replacing a compressor on our air conditioning unit but kept us informed as to their progress. It was frustrating for them on hottest day of year but they kept their professional and customer service attitudes up in a pleasant manner. Two excellent maintenance service repair professionals.
Excelente servicio, el tรฉcnico Dominic muy profesional y muy amable. 100% recomendable
Ali was great! We have a very confusing system here at the office and Ali went over and above and let us know what happened, what he did to fix it, and an action plan going forward. He also provided with solutions and recommendations to corporate in his work order, providing me with peace of mind that our company and the people who need to know what is going on.
Back to normal
They sent someone out when my Central Air died in the middle of a heatwave; it turned out to be frozen so they had to return after it thawed, but everything was timely and I felt well taken care of. Dispatchers, office staff and my tech, Cruise, were all excellent. I was up and running by noon!
Very knowledgeable and professional Navien tech.
Maurice Gaines was friendly, helpful, knowledgeable and efficient! I've used Princeton Air's services a few times now and it's always been a good experience.
Latrelle did an excellent job
I had issues with my A/C unit that would sporadically not turn on and wouldnโ€™t be able to reach the desired set temperature. I had a service contract with the utility company , who I called out 3 times to fix the issue and each time they couldnโ€™t find anything wrong. This time I called Princeton Air, was able to book online and they came out the next day. Ryan came to my house and listened to the entire history of my A/C issues. He was able to troubleshoot and quickly found there was a wiring issue which he was able to correct that day. He educated me on my unit and explained in detail to me everything he did along the way. Thank you Ryan, you are very talented in your skill.
Maurice was terrific and solved the problem very quickly. I highly recommend Princeton Air.
I like to thank Dylan very much. He came to service my AC unit and he found that it was not in service. The refrigerant had leaked out through the coils. Coils were shot. I would have never thought this being a 2-Year-Old AC unit. But fortunately, I did get a service policy and it was under warranty which saved me. Thank you Joe and Tyler also and the girls in the office are just wonderful and will definitely work with you. I've been with this company for over 20 some years and they've always been professional…
Our Tech Dominic was Awesome!! Thank you so much!!
On time. Completed work on all units … Heater, air conditioner, and hot water heater … Within the time frame.
After a few mishaps, Princeton Air came through and got my AC system running when the temperatures are soaring.

Thanks to Will and my technician, Alberto, for getting everything fixed.
Responsive, knowledgeable, dependable, & honest. Thank you for getting out heat up & running!

Update:10/12/18
Chris S got the heat last year and remembered when he arrived today, asked if it had a problem since. He came back to do a PM on the heater and while he was waiting for me to arrive, he opened up the air conditioner to inspect it and saw the coils were filthy. Took out his hose and cleaned them. Then when done, did the heater PM and then โ€œsaid I just want to verify that ringing noise went away. Your house will cool much faster now!โ€ I really like what Princeton air offers, quality and care, diagnose and fix. Not rushing to get to the next job. Theyโ€™re so good I got the year round service plan.

Update may 2025&2026
Maurice is fantastic.
Prompt and knowledgeable. Great technician.
There was an urgent need for a mold problem to be handled in a bathroom. They quickly identified the problem, tested the seriousness, and took care of it – in a very timely fashion. They communicated with me all along the way so I could fully comprehend what was going on. All the people were very knowledgeable, pleasant and accommodating. My experience with them was excellent, and I would highly recommend them.
Eric M. was prompt, professional, courteous and quite helpful. I become a better consumer when I understand the problem & possible solutions. Eric was willing to answer my questions and made me feel secure that he would follow up to help fix our problem.

New review: 2/6/2018
Notice a problem with the humidity in my home, called and got a service appointment in the same day. Will D came out and sure enough, confirmed there was a problem, explained what exactly was happening, why it was happening and how to check that it was working correctly. His demeanor was pleasant, he was professional and seemed to be quite knowledge!

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.
