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 “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.
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!
Great service. Domenic was so helpful and explained everything done.
Jermaine Richmond was very knowledgeable and explained my plumbing issue throughly. Thank you.
Pretty micron air was quick to fix my sewer
Friendly and efficient. Quick response service
Eric did a fantastic job
Installation of water heater hvac and furnace – very professional and process oriented –
The technician who came was Jonathan Redondo. He was very knowledgeable and did an excellent job! I would highly recommend him .
Christian and Mike were professional, thorough, patient, and kind throughout my heating boiler installation.
Always excellent service with McAllister.
Robert came to check my 2 carbon monoxide detectors, which were very old. I decided to have him go ahead and replace them with smoke detector/ carbon monoxide combination units. He was very polite and efficient .
Jihmy and Asterson did an outstanding job and were extremely professional during a recent installation of a mini split and air handler. They communicated well, kept the house clean and did the job with a level of professionalism and expertise that was refreshing.
Good job
Maurice Gaines who cleaned and serviced my air conditioner was fantastic! He was fast, respectful and very fast with the repairs.

He made me feel like I was getting the full respect and honesty I so needed for something so important and really appreciated the time he took to explain every and answer all my millions of questions. Also Princeton Air communications were fast and accurate , leaving no question unanswered as to timing and confirmation of appointment. I’m so happy with their staff and with Maurice- he’s a gem!
Thank you!
The young man who came out to fulfill our annual service contract was extremely professional and was very thorough. Although he told us we needed a new ac unit I felt confident that he knew what he was talking about and took the right amount of time in order to make his recommendation. I want him back every year. Unfortunately I forgot his name because I’m old.

He then had Ricky call us with replacement ac unit recommendations. He was just as professional. He then took the time to visit our condo, take measurements himself and then made recommendations on what size unit to purchase. I really feel he saved us money. He was amazing.

We then were contacted by a gentleman named Steve who was a manager in the service and installation department. It’s hard to believe but he was just as good as the first two representatives and was an absolute pleasure to work with. He was a true professional and a real asset to your organization. I will always use your company if I can work with this team. Keep up the great work. Thanks for allowing me to spend $8,000.its hard to believe I didn’t even get other quotes because I was so happy with your team.

Recently Princeton Air did a routine maintenance check on our HVAC UNIT. The technician was Dominic McGinley. I must say Mr. McGinley was outstanding. After performing the maintenance and evaluation, he sat down with us and explained his findings in precise detail. He has also taken pictures of everything he found. Dominic was a pleasure with whom to interact. He was professional, friendly, and extremely knowledgeable. He explained everything in terms that we could definitely understand. He is one of the finest technicians that has ever performed preventative maintenance on our equipment. In my estimation he has all of attributes of a first rate Service Technician. Hopefully Princeton Air just what a valuable asset he is for the company. I certainly hope to interact with him many times in the future.
We recently used Princeton Air to install a new heater. They gave us lots of options, explained each one thoroughly, they arrived promptly on installation day and did a great job. The price was the lowest of three companies I contacted for estimates. Five stars!
Always professional and informative.

When Does Air Conditioning Replacement Make Sense?

When performance drops or reliability becomes uncertain in your New Brunswick home, continuing to repair an aging system can create more stress than comfort. Not every cooling issue requires a full air conditioner replacement though.

Air conditioning systems in New Brunswick reach the end of their useful life even with proper maintenance. Efficiency drops. Breakdowns become more frequent as components wear down over time. A new system brings back dependable performance and modern efficiency standards.

Normal wear and tear means occasional air conditioning repairs in New Brunswick homes. But when you’re scheduling repeated service calls or dealing with a major component failure, air conditioning replacement in New Brunswick often delivers better long-term value and reliability than continued repairs.

When your air conditioning system in New Brunswick is aging or improperly sized, it struggles to deliver the same level of cooling performance. Unexplained increases in your utility bills often signal that your AC is losing efficiency and working overtime to maintain comfort.

Hot spots plague your New Brunswick home. Humidity problems persist. Constant cycling never stops. These issues often indicate your system is no longer properly matched to your space. Balanced, steady comfort returns with a professionally-installed air conditioning system.



Take the First Step Toward Reliable Cooling in New Brunswick

Frequently Asked Questions

How long does air conditioning replacement take in New Brunswick?

A typical air conditioning replacement in New Brunswick takes one full day from start to finish. Homes with complex layouts, older ductwork that needs updating, or electrical panels requiring upgrades might need an additional day. Our team walks through the timeline with you during the initial consultation. No surprises once installation begins.

Do I need to replace my furnace with my air conditioner in New Brunswick?

Your furnace doesn’t automatically need replacement with a new air conditioner in New Brunswick. A newer furnace in good working order can often pair perfectly with your new cooling system. But if both units are getting older, replacing them as a matched set typically delivers better energy efficiency and performance than mixing old and new components.

How do I know what size AC system my New Brunswick home needs?

Your New Brunswick home’s cooling needs depend on much more than just square footage. Our technicians calculate the exact load by measuring insulation levels, window placement, ceiling height, and how air moves through your specific layout. Getting the size right prevents your new system from cycling on and off constantly. This causes uneven temperatures and shortens equipment life.

What happens to my old equipment after air conditioning replacement in New Brunswick?

Your old air conditioning equipment gets completely removed and properly disposed of during our replacement process in New Brunswick. We handle all refrigerant recovery according to EPA guidelines and recycle materials whenever possible. This removal and disposal service is included with every installation. You don’t need to worry about dealing with the old unit yourself.

Are permits required for air conditioning replacement in New Brunswick?

Most air conditioning replacement projects in New Brunswick require permits and city inspections to verify the work meets safety standards. New Jersey code requirements cover electrical connections, refrigerant lines, and proper equipment mounting. Having permits protects both your home’s safety and your investment. Princeton Air handles all the paperwork and scheduling with local inspectors, so you don’t have to navigate the permit process yourself.
