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.

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

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. Iโ€™m so happy with their staff and with Maurice- heโ€™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 Iโ€™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. Itโ€™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 didnโ€™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.
We just had our A/C serviced by tech Dominic McGinley who performed a thorough spring maintenance. Dominic was very friendly and courteous. He responded in detail to all my questions spending sufficient time with me.
We had valve and service line repairs from Germaine and Bradley, as well as a toilet replacement. They were great!
Julian found an issue with the ac and resolved it. Explained what the component does that needed replacement.

Frequently Asked Questions

How quickly can Princeton Air complete an AC repair in Hillsborough Township?

Most AC repairs in Hillsborough Township can be finished during one service call since our technicians carry common parts and diagnostic tools. We prioritize fast response times when temperatures spike during New Jersey’s humid summers. A failed system can make your home unbearable within hours. For complete breakdowns, we offer around-the-clock emergency service because comfort emergencies don’t follow regular business hours. Some situations simply can’t wait until tomorrow.

Does Princeton Air service all AC brands in Hillsborough Township?

Absolutely. Princeton Air technicians work on all major residential AC brands and system types throughout Hillsborough Township and Somerset County. We train our team on system fundamentals rather than brand-specific approaches. This means we can diagnose problems accurately whether you have a Carrier, Trane, Lennox, or any other manufacturer. This broad expertise helps us get to the root of cooling issues faster, regardless of what nameplate is on your outdoor unit.

How do I know whether to repair or replace my air conditioner in Hillsborough Township?

The decision between repair and replacement depends on your system’s age, the scope of the problem, and whether the repair cost makes financial sense. For AC repair in Hillsborough Township, we look at how old your unit is, its overall condition, current efficiency levels, and past repair patterns before recommending a path forward. The right choice depends on your situation. We’ll walk you through our reasoning clearly so you can make the right call for your home.

What’s the most effective way to prevent AC problems in Hillsborough Township?

Regular professional maintenance prevents most AC breakdowns and keeps your system running efficiently through Hillsborough Township’s hot, humid summers. During these annual visits, technicians clean dirty coils, verify refrigerant levels, inspect electrical connections, and spot small problems before they turn into expensive failures. Between professional visits, changing your filter every few months and keeping the outdoor unit clear of debris helps your system breathe properly. This reduces strain on components.

What should I do if my AC keeps breaking down even after repairs?

Repeated breakdowns typically point to underlying issues like improper system sizing, persistent airflow restrictions, or equipment that’s reached the end of its useful life. Instead of applying temporary fixes to each new problem, we evaluate the entire system to identify what’s causing the pattern of failures. For air conditioning repair in Hillsborough Township, we focus on addressing root causes so your system runs reliably. No more endless loops of service visits.
