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!

Common Furnace Repairs We Handle in Princeton

Over time, even well-built furnaces require attention during NJ’s demanding winters.

Understanding both the problem and its underlying cause is how Princeton Air technicians approach every furnace repair in Princeton. You can be confident the solution addresses the root cause, not just the immediate symptom. Below are some of the most common furnace issues we diagnose and resolve for homeowners throughout Princeton every day.

A furnace that won’t start or begins running only to shut down moments later typically points to ignition system or pilot light trouble. Clicking sounds, delayed ignition, or cycling without steady heat production are common signs Princeton homeowners notice. Our Princeton Air technicians carefully inspect these components, determining whether wear, buildup, or electrical failure is the root cause. Proper ignition gets restored so your furnace starts smoothly and delivers reliable operation when you need it most.

Princeton homeowners notice their furnace cycling on but only cool air flowing through the vents. The heating system has lost its ability to generate warmth effectively. Common culprits include faulty ignition components, blocked airflow pathways, thermostat malfunctions, or failing internal parts that prevent proper heat exchange. Our experienced technicians diagnose the specific issue affecting your furnace repair in Princeton and restore dependable warmth to your home.

Strange sounds from your furnace often signal internal components beginning to fail, especially during Princeton’s cold snaps when systems work hardest. A rattling blower motor or grinding noise that seems minor today can escalate into costly damage if ignored through New Jersey’s demanding winter months. Princeton Air’s technicians quickly identify whether loose parts, worn bearings, or mechanical stress is causing the disturbance, then complete targeted furnace repair in Princeton that restores quiet, dependable operation before small problems become major breakdowns.

Princeton homeowners notice their heating bills climbing unexpectedly. This often signals a furnace struggling against New Jersey’s demanding winter conditions. Worn components, clogged filters, or declining system performance force your equipment to consume more energy while delivering less warmth. Our technicians identify what’s causing the inefficiency and provide targeted furnace repairs in Princeton that restore proper operation and reduce energy waste.

Princeton homes with uneven heating or temperatures that won’t match your thermostat setting often face thermostat calibration issues or communication breakdowns between the control and heating system. Older Princeton residences near the university area particularly struggle with this during New Jersey’s variable winter conditions. Thermostats may misread actual room temperatures or lose proper signal connection to the furnace. Our technicians in Princeton evaluate the entire control system and its wiring to restore precise temperature regulation throughout your home.

Short cycling in Princeton furnaces often occurs when heating systems work overtime against New Jersey’s fluctuating winter temperatures, causing the unit to start and stop repeatedly rather than running steady cycles. This pattern wastes energy and accelerates wear on critical components throughout your system. Princeton Air technicians pinpoint what’s driving the cycling behavior and deliver targeted furnace repair in Princeton, addressing everything from faulty thermostats to restricted airflow or aging internal parts.

Frequently Asked Questions

How do I know if I need furnace repair in Princeton?

Signs that point to furnace trouble in Princeton often start subtly. Rooms won’t warm up evenly, strange sounds when the system runs, or frequent cycling on and off. More obvious problems include a furnace that won’t start at all or can’t hold the temperature you’ve set on your thermostat. Having a Princeton Air technician evaluate your system gives you a clear picture of what’s wrong and whether repairs can restore dependable heating to your home.

How quickly can you respond to furnace repair calls?

We provide 24/7 emergency furnace repair in Princeton, NJ, and can often arrange same-day service when your heating fails unexpectedly. Our response times stay shorter because Princeton Air technicians are already stationed throughout Mercer County, not dispatched from distant locations. During heating emergencies, we prioritize urgent calls to get your warmth restored as quickly as possible.

Do you service all furnace brands?

Our technicians work on all major furnace brands and models you’ll find in Princeton homes, from decades-old units to today’s high-efficiency systems. This broad experience with different manufacturers means we can quickly identify what’s wrong with your specific equipment and know which repair methods work best for each type. Whether you have a gas, electric, or oil furnace, we’ve seen the common issues that affect each brand and understand how to fix them properly.

Should I repair or replace my furnace?

Your furnace’s age, the specific problem, and your repair history all play into this decision. A 10-year-old system with a minor issue usually makes sense to repair, while a 20-year-old furnace needing major work often points toward replacement. Princeton’s cold winters mean your heating system works hard, so we evaluate how much life your current equipment realistically has left. Our technicians explain what we find and give you straightforward guidance so you understand which path makes the most sense for your situation.

How can I reduce the risk of future breakdowns?

Regular maintenance is your best defense against surprise furnace breakdowns. During annual tune-ups, technicians clean components, check for wear, and test system performance to catch small issues before they become major problems. Princeton’s cold winters demand reliable heating, so many homeowners join maintenance programs like the Princeton Air Comfort Club to get scheduled service, priority response, and system monitoring that keeps their furnace running dependably when they need it most.
