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.

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.

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

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.

Replacing Your Furnace Before a Breakdown Is a Wise Decision

Most furnace failures aren’t sudden; they’re the result of years of strain.

When furnace repair in Hamilton Township becomes a recurring expense — the same issues returning, costs climbing, reliability fading — replacement stops the cycle. Replacing before a breakdown allows you to plan calmly, choose the right system, and protect your home on your terms.

When you replace your furnace in Hamilton Township on your schedule, you avoid the stress of a cold home and rushed decisions. You choose the timing that works best for your family and your household routine.

Without the pressure of an outage, we carefully evaluate your Hamilton Township home and recommend the right furnace replacement for balanced comfort, efficiency, and longevity. It’s a measured decision, not a reactive one.

Older furnaces in Hamilton Township often run longer and work harder to produce the same warmth. A properly sized, modern system can deliver more consistent heat while using less energy, helping protect your long-term operating costs.

The coldest days in Hamilton Township are when aging systems are most likely to fail. Replacing early reduces the risk of mid-season breakdowns, frozen pipes, and the strain that sudden heat loss can place on your home.

When Is It Time to Start Thinking About Furnace Replacement?

Furnaces rarely fail without warning. Recognizing those signs early allows you to plan thoughtfully, rather than being forced into a decision during the coldest week of the year.

Even well-maintained furnace systems in Franklin Park and throughout Hamilton Township have a lifespan. If your furnace is approaching 15 years or more, efficiency typically declines and internal components begin to wear. Planning ahead gives you control over timing and options.

An occasional furnace repair in Hamilton Township is normal. But if service calls are becoming routine or costs are adding up, it may be more prudent to invest in long-term reliability instead of continued short-term fixes.

Older furnaces often work harder to produce the same warmth. If your utility bills continue climbing despite normal usage, declining efficiency may be quietly costing you each month.

Cold spots, longer run times, unusual noises, or dry air can indicate a system that’s struggling to keep up. When comfort becomes inconsistent, it’s often a sign the system is no longer performing as your home requires.



Your Next Step Toward Reliable Winter Comfort

When your furnace can no longer deliver the warmth and reliability your home deserves, you don’t have to navigate the decision alone.

For over 50 years, Princeton Air has provided furnace replacement in Groveville and throughout Hamilton Township with integrity and lasting care. We take the time to evaluate properly, recommend thoughtfully, and install thoroughly so your new heating system performs the way it should for years to come.

Schedule your in-home evaluation with Princeton Air today. Let’s restore dependable heat and the quiet confidence that your home is ready for whatever winter brings.
