MOST RECENT June 2026:
Weltman has been purchased by Princeton Air. They have been really great. A seamless transition on the customer side. Eric was just here to put in a new anti-scaling system and a pressure relief valve for the house. Very happy!

UPDATE:
Now in our home for almost 8 years and Weltman has never disappointed! Chris L came today and was completely professional and quick for our yearly inspection of our furnace before the cold winter! Itโ€™s great to know they keep great notes and, almost, know more about our system than we do!

Weltman will always make it right if something is wrong. They will also get to you ASAP! We have been customers since we bought our home 3 years ago and have been completely satisfied!
Teck was knowledgeable and courteous
The technician Alfredo is great
I was recommended Princeton Air by a friend and Iโ€™m very happy that I was. I had a hvac and furnace system that was 25 years old and in dire need of replacement.
Chris from the company came out very promptly and did a full review, taking the time to take me through the different options. From there we reached an agreement and within one week the team came out and did a full dual zone system replacement.
I was blown away by the professionalism and indeed sheer hard work of the installation team. They arrived at 08.30am and finished at 8.30pm working tirelessly to complete the job in one day. A huge thank you to Princeton air, Chris and the install team -Jorge Vizueta, John Jaramillo, Juan Torres and Jhonny Anacona for a really cool air conditioning experience. Thank you!
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.
Norman was great!!! He has come before. His advice and work were great!!!! Unfortunately Princeton Air, formerly a family run business, has been bought by a large corporate group, and we have chosen not to use them any longer
The technician was thorough, knowledgeable and professional. He also called for an ETA and was punctual.
I wanted to say a BIG Thank you to Princeton Air and Jesus C for coming to our rescue when AC in our house wasnโ€™t working (despite it working fine 3 weeks ago). My daughter and her friends arrived on Friday afternoon for a girls weekend. Even though the compressor unit outside was running, no air was coming through the vents inside the house. After talking her through a few things over the phone (none of which resolved the issue), I called Princeton Air.
Despite it being already 5pm on Friday, they dispatched a technician who arrived within an hour. Jesus C called me several times to keep me updated about the repair. Within 45 min, the air was blowing COLD!!
I highly recommend this company. I am beyond grateful for the prompt and professional service we received.
Thanks so much for the EXCELLENT service from Norman. He was very knowledgeable and so friendly. Really nice guy. Thank you Norman and thank you Princeton Air.
Just to let you know everything here is fine. Norman was wonderful!! Helpful and very friendly. Thank you Norman and thank you Princeton Air.
Great service , Ryan was fantastic
We recently had a new AC unit installed by Princeton Air and had a great experience from start to finish. The installation went smoothly, the team was professional, knowledgeable, and respectful of our home, and we are very satisfied with the quality of the work.
We did have one minor issue after the installation, but Dominic McGinley responded quickly and took care of it right away. His prompt service and commitment to making sure everything was working properly really stood out.
Overall, weโ€™re very happy with Princeton Air and would highly recommend them to anyone looking for HVAC services.
Excellent technician with thorough explanation of the problem
Dillion was very pleasant ,He informed me what he was going to do what Needed to be done and afterwards Everything that was completed
Jorhe arrived and listened to what I needed in this routine service call and when he finished all my questions were answered & for the 1st time Iโ€™m able to understand the function and area each thermostat controls!
Cheers for you Jorhe!

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.
