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.
Service man Ryan is always very professional and thorough and takes the time to explain whatโ€™s going on with our heating and air-conditioning system.
I waited all day three times for the repairman. I am going to change my service provider.
Technician was very good.
Prompt, polite, informative, professional, thorough
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.
Iโ€™m very happy with my new system.
Thank you Princeton Air.
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.
Excelente servicio, el tรฉcnico Dominic muy profesional y muy amable. 100% recomendable
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.
Back to normal
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!
Very knowledgeable and professional Navien tech.
Maurice Gaines was friendly, helpful, knowledgeable and efficient! I've used Princeton Air's services a few times now and it's always been a good experience.
Latrelle did an excellent job
I had issues with my A/C unit that would sporadically not turn on and wouldnโ€™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 couldnโ€™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.
Maurice was terrific and solved the problem very quickly. I highly recommend Princeton Air.
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…
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 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.

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!

Water Heater Repairs

A struggling water heater means laundry that can’t get done, dishes that don’t get clean, and a household that can’t run the way it’s supposed to.

Our Princeton water heater repair specialists restore hot water daily throughout neighborhoods like Jugtown, Western Section, Riverside, and Tree Streets.

After identifying what went wrong, we outline the solution clearly. We perform every water heater repair in Princeton with the precision and care your home deserves. The repairs we make are built to last, so you can be confident your water heater is fixed correctly. Common water heater problems we resolve include:

Failed heating elements, tripped breakers, thermostat malfunctions, or pilot light problems can all cause a complete loss of hot water in Princeton homes. Quick diagnosis and safe system restoration are what our technicians deliver when you’re facing this frustrating situation.

Water that jumps from scalding to lukewarm without notice typically stems from sediment buildup, a degraded thermostat, or worn heating components. Our Princeton technicians diagnose the root cause and correct it. This restores steady hot water temperatures throughout your home.

Moisture appearing around your water heater in Princeton demands immediate professional attention. Early intervention on leaks prevents costly water damage throughout your home. These leaks might stem from loose fittings, faulty valves, or tank compromise.

Sediment accumulation at the bottom of the tank commonly produces banging, rumbling, or popping sounds in Princeton water heaters. This buildup strains the system and reduces efficiency when left unaddressed. Professional servicing can often resolve the issue effectively.

Internal corrosion or a deteriorating anode rod often causes rusty, cloudy, or unpleasant-smelling hot water in Princeton homes. Addressing these issues promptly can protect your plumbing system and extend your water heater’s usable life.

Water Heater Replacement

There comes a point when repairing an aging system no longer makes sense. Time for Princeton homeowners to upgrade their water heaters.

Princeton homeowners facing water heater replacement can count on Princeton Air for honest guidance and carefully matched equipment. Our installations are built for long-term performance throughout Mercer County neighborhoods.

Replacing your water heater in Princeton represents an investment in your home’s comfort and long-term stability. Our team will help you determine when replacement becomes the wisest choice for your situation.

Once water heaters reach the 10-to-12-year mark, efficiency starts declining while breakdown risks increase significantly. Princeton homeowners who replace their aging units proactively avoid the uncertainty and potential emergency situations that come with older systems.

A single repair call is normal maintenance. But multiple service visits to the same Princeton water heater signal deeper system deterioration. Rather than continuing to patch a failing unit, replacement typically provides better long-term value for homeowners.

Your Princeton water heater’s capacity starts declining. Showers turn cold unexpectedly. The dishwasher and laundry fight for hot water. This typically signals reduced heating performance or sediment buildup affecting capacity. Replacement brings back the reliable hot water output your household depends on.

Visible rust on the tank body or around fittings in Princeton homes usually signals deeper internal deterioration that’s already underway. Corrosion tends to progress once it starts. This means the risks of continued operation grow over time.

Water pooling around the base of your Princeton water heater signals a serious problem that demands immediate attention. Internal tank failure is typically the culprit when leaks originate from the unit itself. This makes replacement the safest and most practical solution for homeowners.

Water Heater Maintenance

The best way to avoid an unexpected breakdown is to make sure your system never reaches that point in the first place.

Regular water heater maintenance ranks among the smartest investments Princeton homeowners can make. Our tune-up service at Princeton Air allows technicians to identify emerging problems before they escalate, bring efficiency back to peak levels, and make sure your system operates safely throughout Mercer County’s varied seasonal conditions.

During a water heater tune-up in Princeton, our technicians typically perform the following steps:

  • Flush the tank to remove sediment
  • Inspect the anode rod
  • Test the temperature and pressure relief valve
  • Check heating components
  • Inspect for leaks or corrosion
  • Verify thermostat settings
  • Evaluate overall system performance

Water Heater Installation

From morning showers to evening clean-up, your water heater in Princeton supports the routines that make daily life comfortable.

The installation process becomes straightforward when Princeton homeowners work with Princeton Air. We start by understanding how your household uses hot water, followed by equipment recommendations that align with your needs and budget. Every installation in Princeton gets completed with the precision and care that professional work demands.

We look at the bigger picture. Several key factors guide our recommendations.

Your daily hot water habits, household size, and the number of bathrooms all influence the right tank size for your Princeton home. Peak demand shortages result from systems that are too small, while oversized units waste energy unnecessarily. Our technicians help you find the right fit from standard tank water heaters that range from 30 to 80 gallons.

Modern water heater technology offers dramatically improved efficiency compared to models manufactured just ten years ago. High-efficiency systems in Princeton homes cut energy consumption while maintaining strong performance throughout the equipment’s operational life.

Princeton homes present unique installation challenges that require careful space assessment. Our technicians thoroughly evaluate basement installations, utility closets, and garage locations to verify proper fit and adequate clearance. Safe access for future service calls remains a priority throughout the planning process.

Both gas and electric water heaters offer distinct benefits. The ideal option is typically determined by your Princeton home’s current infrastructure. After reviewing your existing plumbing and utility connections, our team recommends the water heater system that works best with your home’s setup.

The installation quality directly determines your water heater’s long-term reliability in Princeton. Every connection, fitting, and safety check receives precise attention from our technicians. All work meets code requirements. Complete system verification happens before we consider the job finished.

Frequently Asked Questions

How long should I expect my water heater to last?

Traditional tank water heaters generally run 8 to 12 years in Princeton homes when properly maintained. The mineral content in your local water supply, how heavily your household uses hot water, and whether you keep up with yearly maintenance all affect how long your unit will last. Regular professional service helps you get the full lifespan out of your system and prevents unexpected breakdowns.

How do I choose the right size water heater for my Princeton home?

Your household’s hot water demand determines the right tank size for your Princeton home. A family of four typically needs a 50-gallon unit, while larger households or homes with multiple bathrooms may require 60 to 80 gallons. Peak usage patterns matter too. If everyone showers in the morning or you run the dishwasher and laundry simultaneously, you’ll need extra capacity to handle those demand spikes without running out of hot water.

What’s involved in a water heater installation, and how long does it take?

A typical water heater installation in Princeton takes 3 to 6 hours from start to finish. The work involves disconnecting and removing your old unit, positioning and connecting the new system to your existing plumbing and electrical or gas lines, then running complete safety and performance tests. Installation time can stretch longer if your home needs updated connections or if you’re switching from one fuel type to another.

How often should I schedule water heater maintenance in Princeton?

Most water heaters in Princeton should get professional maintenance once a year. During that service visit, technicians flush out mineral buildup, test safety valves, and spot developing issues while they’re still minor repairs instead of major breakdowns. Regular yearly care keeps your system running reliably and helps you avoid the expense of premature replacement.

What warning signs mean my water heater needs professional attention?

Several key symptoms signal your water heater needs professional attention. Water temperature that fluctuates unexpectedly. Hot water running out faster than usual. Strange noises like banging or popping from the tank. Rusty or foul-smelling water, and any signs of leaking around the base. Princeton’s mineral-rich water can speed up some of these problems, particularly sediment buildup that causes noise and capacity issues. Address these warning signs promptly. You’ll typically deal with a straightforward repair rather than a costly emergency replacement.
