The Tech arrived on time, quickly figured out the problem with my AC and fixed within an hour. Pricing reasonable and professional service. Highly recommend!
Cruise was great! He addressed our AC issue quickly and professionally.
Weโ€™ve always been satisfied with McAllister and our recent experience since the merger has not changed that. We needed a new condenser for the A/C and they had a cost effective solution and were able to install it quickly.
Very efficient and on time
Princeton Air condition was extraordinary!! I received a very fair quote immediately after Inspection of my HVAC systemby their talented technician. Their technicians were prompts, professional, and polite. They installed a new system with precision and followed up Professionally. Totally proud to work with Princeton.!!
Ryan G came by and provide tips and recommendations so thorough and with full clarity that I believe will benefit in the long haul. Because of this, I was confident to re-sign up for their maintenance program. He was a true professional who is highly knowledgeable and enthusiastic with the work that he is called to do.
We had Norman. He was here a few hours and checked out my HVAC systems for the summer.
He was careful and professional.
Jose and Corey were a great team and genuinely seemed to care about solving our issues.
I had A/C installed in May, but waited to write a review to see how effective the units can be once it's hot out. Now that I've gone through a couple high temperature days where I turned the mini splits on, I can post a review that I am completely satisfied with the installation by Princeton Air Conditioning and the ease of usage of units. I also will add that it was a pleasure to have Mike C. and Christian J. on the job; they, along with the crews that were on site over the course of the two days, were professional, communicative and upfront. I'd recommend this company to anyone looking for services.
Professional and friendly staff
Air conditioning wasn't working and they came out and got it fixed within a day. Ryan did a great job making sure everything was up and running quickly.
The job was done smoothly and efficiently and right on time
Ryan G got our old air conditioner working again quickly during a bad heat wave and, when we were ready, he explained all our options very well and laid the groundwork to make it easy for us to have installed a new air conditioner. Plus he rescued our cat three times when our cat tried to get out through the garage. He was very kind to all our pets and to us. Thank you, Ryan G!
Dominic was extremely pleasant, professional, and thorough,. He was also quite efficient. He quickly diagnosed the situation and was able to correct it. He also took the time to patiently explain my thermostat to me. Then he signed me up as a member. So heโ€™s a pretty good sales guy too!
However, I then set up an appointment for maintenance and twice Princeton Air canceled me. Iโ€™m now set up for maintenance the end of June. And thatโ€™s after they tried to set me up the end of July and I complained.And this is after Dominic signed me up as a member. Thereโ€™s something very wrong with their business model and I do not consider this good customer service. I will likely have to look for a different serviceโ€ฆ. something more responsive.
Tech (Alex) was on time, courteous, very professional. He let me know that, because of my contract w/McCallister, I would have no extra payment for the part needed.
The repair man, Dominic came out this morning to inspect our AC system. He was extremely knowledgeable, incredibly kind, and explained things very well. I work in construction and can tell you that Dominic is one of the best Iโ€™ve seen in years. Princeton air is very lucky to have him as an employee as he is SUCH AN ASSET to your company.

I also want to give a special thanks to Leah the customer service representative I spoke to. Also extremely kind and helpful. I have had the worst two weeks of my life and two strangers taking the time to kind made my heart smile. Thanks again Leah and Dominic. Chuck our Project Manager has been very kind and knowledgeable through this process as well. I am grateful for the people who work here as they made this pretty easy. Thank you all so much.
Latrell Romulus from Princeton Air did a great job of making sure my AC units were working properly. He was thorough and knowledgeable, and communicated potential areas of concern in a very clear manner.
Great job ! Very knowledgeable and informative. He made sure I was aware of any issues and explained it thoroughly! I look forward to having him again !!
Ryan did a fantastic job for us. He was patient and thorough. Thank you, way to go.
This is an outstanding company on all levels.
The team at Princeton Air Conditioning has been excellent. Wilver Matos was great, knowledgeable, customer service oriented and willing to help. He was also preemptive in solutioning comprehensively for the water heater installation especially since there was some mix-up originally but he worked to sort it out.


Comprehensive Heating Services

At Princeton Air, we specialize in a full range of heating services to keep your system running efficiently:

Furnace icon

Furnaces

For many New Jersey homes, the furnace delivers steady, reliable heat when it matters most.

When something feels off, it can disrupt more than temperature. It affects your sense of ease at home. Princeton Air cares for furnace systems with a focus on safety, longevity, and thoughtful performance, so your home remains warm and dependable.

  • Furnace Installation: A furnace should fit your home, not the other way around. For homes across Morristown and the surrounding area, we evaluate how your home holds heat, how air moves, and where inefficiencies exist before recommending a system. Installation is handled with precision and full code compliance, ensuring quiet, even warmth without strain or waste.
  • Furnace Repair: Furnace issues are often symptoms of something deeper. Princeton Air identifies the cause, corrects it thoroughly, and stabilizes the system so you’re not dealing with repeat issues weeks later.
  • Furnace Maintenance: Consistent care keeps your system dependable. Furnace maintenance from Princeton Air goes beyond a quick check. We clean, calibrate, and verify safe operation so your furnace performs reliably when you need it most.
  • Furnace Replacement: When repairs become frequent or performance declines, replacement becomes an opportunity. Homeowners in Maplewood and Mount Laurel who’ve carried aging furnaces through multiple winters often find that a modern system delivers more consistent heat, improved efficiency, and quieter operation without overcomplicating the decision.
Heat pump icon

Heat Pumps

Heat pumps offer a more balanced, efficient way to care for your home, but only when they’re properly designed and supported.

When they’re not, comfort can feel uneven or unpredictable. With our heat pump services in New Jersey, Princeton Air brings that balance back, so your home feels consistently right in every season.

  • Heat Pump Installation: We design systems that match your home’s layout and demands, not just square footage. For properties in Bedminster and similar communities where layouts vary widely, the result is a heat pump that maintains even temperatures, operates quietly, and supports long-term efficiency.
  • Heat Pump Repair: When performance drops, you may notice subtle signs like longer run times, weaker airflow, and inconsistent temperatures. Princeton Air identifies where the system is losing efficiency and restores it with targeted, lasting repairs.
  • Heat Pump Maintenance: Because heat pumps run year-round, they require a higher level of care. Princeton Air keeps components clean, settings optimized, and performance steady so your system doesn’t gradually lose effectiveness.
  • Heat Pump Replacement: Modern heat pumps offer meaningful improvements in comfort and efficiency. For homeowners in Plainsboro and across the service area, we guide you through the options clearly, helping you upgrade without guesswork or unnecessary complexity.

Oil-to-Gas Conversions

If your home still relies on oil heat, rising fuel costs and storage concerns often push the question of whether natural gas would serve the house better.

Princeton Air manages the full conversion, from system design and removal through installation and permitting, with everything handled properly inside your home.

Ductless system icon

Ductless Mini-splits & VRFS

Some homes and some spaces need a more tailored approach to comfort.

Ductless systems provide that flexibility, offering precise control without invasive installation. When designed properly, they quietly solve comfort challenges without disrupting the character of your home. Princeton Air offers complete ductless services for homeowners across New Jersey.

  • Ductless Mini-Split Installation: Placement matters as much as the system itself. Princeton Air designs ductless solutions across Chatham and similar communities that integrate cleanly into your space, delivering targeted comfort while maintaining a low visual profile.
  • Ductless Mini-Split Repair: When a unit isn’t performing as expected, the issue is often overlooked or misread. When you call Princeton Air for ductless repair, we diagnose accurately and restore performance without unnecessary adjustments or disruption.
  • Ductless Mini-Split Maintenance: Keeping filters, coils, and components clean ensures your system runs quietly and efficiently. Regular service from Princeton Air protects both performance and indoor air quality.
  • Ductless Mini-Split Replacement: Upgrading a ductless system is an opportunity to refine comfort even further. For homes in West Windsor and across the service area, newer systems offer better control, quieter operation, and improved efficiency, allowing each space in your home to feel exactly how you want it to.
  • Multi-Zone Ductless Design: When a home has several rooms with different comfort needs, a multi-zone ductless system gives you independent control in each space. We design these systems carefully, matching capacity to the actual demand in each room rather than installing the same unit everywhere.
Boiler icon

Boilers

Boiler heat is different from forced-air heat. It’s quieter, more even, and more subtle.

When it’s working properly, you hardly notice it. When it’s not, the discomfort feels deeper. Princeton Air’s New Jersey boiler services preserve that quiet reliability while ensuring your system operates safely and efficiently.

  • Boiler Installation: Boiler systems demand precision. From piping layout to pressure balance, every detail matters. Princeton Air installs new boilers across Hopewell and the surrounding communities with a methodical approach that protects both performance and longevity.
  • Boiler Repair: Boiler issues can be complex and are often misdiagnosed. Princeton Air technicians take the time to assess the full system and resolve the issue in a way that restores consistent, even heat without compromising safety.
  • Boiler Maintenance: Routine service helps prevent pressure problems, inefficiencies, and unexpected failures. Boiler maintenance from Princeton Air keeps your system tuned and monitored so it continues to deliver the steady warmth you rely on.
  • Boiler Replacement: When a boiler has reached the end of its service life, continued repairs rarely pay off. In older homes across Lawrence Township with boilers that have been running for thirty years or more, modern replacement delivers better comfort, meaningfully lower fuel use, and the quiet reliability that made you choose a boiler in the first place.
Smart thermostat icon

Smart Controls and Thermostat Integration

An outdated or poorly configured thermostat leads to uneven temperatures, wasted energy, and constant adjustments that interrupt your day.

We pair heat pump systems with thoughtfully selected smart thermostats and home comfort controls designed around how you actually live.


By focusing on energy efficiency and expert craftsmanship, Princeton Air helps homeowners reduce energy costs while ensuring reliable heating performance.
