Jacie Rypin
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.
Melissa Lucas
Service man Ryan is always very professional and thorough and takes the time to explain what’s going on with our heating and air-conditioning system.
Karen Uhlenbeck
I waited all day three times for the repairman. I am going to change my service provider.

Prompt, polite, informative, professional, thorough
Debbie Kroll
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.
I’m very happy with my new system.
Thank you Princeton Air.
Robert Arimenta
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.

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.

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!
Tony Esposito
Very knowledgeable and professional Navien tech.

Latrelle did an excellent job
Christine Sfraga
I had issues with my A/C unit that would sporadically not turn on and wouldn’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 couldn’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.
Susan Davis
Maurice was terrific and solved the problem very quickly. I highly recommend Princeton Air.
Patricia Layton
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…
Paulette Briddle
Our Tech Dominic was Awesome!! Thank you so much!!
Paulette Laubsch
On time. Completed work on all units … Heater, air conditioner, and hot water heater … Within the time frame.
Emily Escott
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.
Stephen O'Reilly
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 “said I just want to verify that ringing noise went away. Your house will cool much faster now!” I really like what Princeton air offers, quality and care, diagnose and fix. Not rushing to get to the next job. They’re so good I got the year round service plan.

Update may 2025&2026
Maurice is fantastic.
Zebulon Nelessen
Prompt and knowledgeable. Great technician.
Gina Clark
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.
Marsha Goy
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!

Replace Your Furnace Before It Leaves You in the Cold

Princeton temperatures drop and your heat goes out. That’s exactly when you don’t want to be dealing with a failing furnace.

An aging system can only be carried so far by repairs. Princeton homeowners eventually face the decision of whether their furnace is still worth fixing. Here’s how to know when replacement makes more sense than scheduling another service call.

One repair is normal, but two in the same season signals trouble ahead. Princeton homeowners dealing with a furnace that’s become a recurring winter expense will likely find replacement the smarter long-term investment.

Furnaces are built to last, but they don’t run forever. Princeton homeowners with systems that have crossed the 15-to-20-year threshold often find themselves spending more on repairs and energy costs than a new furnace would cost to operate. The financial equation shifts rapidly toward replacement once your system reaches this age.

Some rooms in your Princeton home stay cold while others overheat. Your furnace has likely lost its ability to distribute heat evenly throughout the space. Those frustrating cold pockets disappear for good with a properly sized new system.

Princeton homeowners often don’t realize their furnace efficiency is declining until monthly utility bills reveal the truth. Older systems gradually lose their ability to heat effectively. A high-efficiency replacement delivers the same warmth while using measurably less fuel.

What a New Furnace Actually Does for Your Home

A furnace replacement changes the way your home feels, functions, and costs to run every single day.

Long before they stop working altogether, older furnaces lose their ability to distribute heat evenly throughout Princeton homes. That one room nobody wants to sit in during January? Those cold bedrooms and drafty hallways? They’re often symptoms of a struggling system rather than a layout problem with your home. Balanced, consistent warmth from room to room gets restored with a properly sized new furnace. You’ll experience comfort you might not have felt in years.

Owning an unreliable furnace creates a particular kind of anxiety as New Jersey winter approaches. That nagging question of whether this is finally the season it gives out completely. Princeton Air’s new systems eliminate that worry entirely. You’ll have a furnace you can count on completely when cold weather hits Princeton.

Constant banging, rattling, or cycling on and off means your furnace is trying to tell you something important. Princeton homeowners who’ve lived with the noise for years are often amazed by how quietly new systems operate. The warmth arrives without the sound. You’ll feel the comfort, not hear the struggle.

Today’s high-efficiency furnaces pull significantly more heat from the same fuel compared to systems that are even a decade old. Across an entire Princeton heating season, that efficiency gap really adds up. Homeowners throughout Princeton who replace aging equipment consistently notice meaningful drops in their monthly utility costs. Those savings accumulate year after year throughout the system’s lifespan.

Frequently Asked Questions

How quickly can Princeton Air replace my furnace?

A typical furnace replacement in Princeton gets finished within one day from start to finish. We bring your new equipment, handle the complete installation, test everything thoroughly, and clean up before we leave. All in a single visit for most homes. If ductwork changes are required, we identify that during our initial assessment and provide you with a clear timeline before any work starts.

Can replacing my furnace actually lower my heating bills in Princeton?

Absolutely, particularly if you’re replacing a furnace that’s 10+ years old. Today’s high-efficiency models pull much more heat from each unit of fuel compared to older systems. This translates to lower monthly bills for Princeton homeowners. Those energy savings add up significantly over the years, making the efficiency gains a real financial benefit throughout the system’s lifespan.

How do you determine what size furnace my Princeton home needs?

We calculate the exact heating load your Princeton home requires rather than simply matching your existing unit’s size. Our technicians measure square footage, evaluate insulation levels, assess your home’s layout and ductwork condition, plus other factors that affect heat distribution throughout your space. Getting the size wrong creates comfort problems and higher energy costs. We run the numbers to match your furnace perfectly to your home’s actual heating demands.

Does Princeton Air offer financing for furnace replacement?

Yes, we provide financing options that help Princeton homeowners manage the cost of furnace replacement without creating immediate budget pressure. These programs work through local utility partnerships and spread payments over time. This makes a new heating system more manageable financially. Our team can walk you through what’s currently available once you’re ready to move forward.

Who handles the permits for furnace replacement in Princeton?

Princeton Air handles all permit paperwork and inspection scheduling for your furnace replacement in Princeton, NJ. We pull the required permits, coordinate with local inspectors, and make sure everything meets New Jersey code requirements. You won’t need to deal with any of the administrative details. We manage that entire process from start to finish.
