Princeton Air Conditioning replaced my 25 year old central air conditioner. The sales person was very knowledgeable, made sure I was getting the correct size unit, explained the available options and got a quote out very quickly.

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. A household that can’t run the way it’s supposed to.

Every day across Woods Tavern, Neshanic Station, Belle Mead, and Flagtown, Princeton Air’s water heater repair specialists in Hillsborough Township work to restore hot water to local homes.

Clear explanations of what went wrong come first. Then detailed solutions and water heater repairs in Hillsborough Township performed with the precision your home deserves. The repairs we complete are built to last, giving you confidence in the work. Common water heater problems we resolve include:

Hot water disappears completely in your Hillsborough Township home? The culprit could be a failed heating element, tripped breaker, thermostat malfunction, or pilot light that’s gone out. Our technicians quickly pinpoint the source of the problem and get your system back up and running safely.

Water that fluctuates unpredictably between scalding hot and lukewarm temperatures in your Hillsborough Township home typically stems from sediment buildup. Thermostat degradation or worn heating components can also cause this. Our team diagnoses the root cause and corrects it, restoring the steady hot water temperatures you need.

Moisture around your water heater in Hillsborough Township demands immediate attention. Loose fittings, faulty valves, or a compromised tank can all be the culprit. Early intervention prevents water damage and protects your home from costly repairs.

Sediment accumulation at the bottom of the tank typically produces banging, rumbling, or popping sounds in Hillsborough Township homes. This buildup strains the system and reduces efficiency if left unaddressed. Professional servicing can often resolve the issue effectively.

Hot water in your Hillsborough Township home appears rusty, cloudy, or carries an unpleasant smell? Internal corrosion or a deteriorating anode rod is often the cause. Addressing these issues promptly protects your plumbing system and extends your water heater’s usable life.

Water Heater Replacement

There comes a point when repairing an aging system no longer makes sense. It’s time for Hillsborough Township homeowners to upgrade their water heaters.

Hillsborough Township 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 in Somerset County homes.

Replacing your water heater in Hillsborough Township represents a significant investment in your home’s comfort and long-term stability. Our team will guide you through determining when replacement becomes the most practical choice for your situation.

Water heaters reach the 10-to-12-year mark in Hillsborough Township homes, and efficiency starts declining while breakdown risks increase significantly. An aging unit brings uncertainty that proactive replacement eliminates. This protects your home from unexpected failures.

A single repair call is normal maintenance. The same water heater in Hillsborough Township requires multiple service visits? That indicates deeper system deterioration. Rather than continuing to patch a failing unit, replacement usually provides superior long-term value for homeowners.

Your Hillsborough Township home’s hot water runs out faster than usual? Showers cutting short or the dishwasher and laundry unable to run simultaneously? Reduced heating performance or sediment buildup is typically the culprit. Replacement brings back the reliable capacity your household depends on.

Visible rust on your Hillsborough Township water heater’s tank or around connections usually signals more serious internal damage beneath the surface. Corrosion tends to spread once it starts, making continued operation increasingly risky.

Water pooling around your Hillsborough Township water heater’s base signals a serious problem that demands immediate attention. Internal structural failure is typically the cause when leaks originate from the tank itself. This makes replacement the safest and most practical solution.

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 any Hillsborough Township homeowner can make. Our Princeton Air tune-up service allows technicians to identify emerging problems before they worsen, bring efficiency back to peak levels, and confirm your system operates safely throughout Somerset County’s varying seasonal demands.

During a water heater tune-up in Hillsborough Township, 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 Hillsborough Township supports the routines that make daily life comfortable.

Homeowners throughout Hillsborough Township can navigate the installation process with confidence when they work with Princeton Air. Understanding how your household uses hot water comes first, followed by equipment recommendations that match your specific needs and budget, then completing every installation with the precision and care that professional work demands.

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

Your household size, bathroom count, and daily hot water usage patterns all determine the appropriate tank capacity for your Hillsborough Township home. Too small a system creates shortages when demand peaks, while an oversized unit wastes energy unnecessarily. Our technicians help you select the right fit from standard tank water heaters that range from 30 to 80 gallons.

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

Location considerations play a crucial role in water heater installation in Hillsborough Township. Our technicians carefully assess basement installations, utility closets, and garage spaces to confirm proper fit and adequate clearance, while also verifying safe access for future service needs.

Each fuel type brings distinct benefits to Hillsborough Township homeowners, with gas and electric water heaters offering different advantages based on your home’s current infrastructure. After reviewing your existing plumbing and utility connections, our team recommends the water heater system that works best with what’s already in place at your property.

The installation behind your water heater determines its long-term reliability. Every connection, fitting, and safety check receives precise attention from our technicians in Hillsborough Township, with all work meeting code requirements and your system verified safe before we complete the job.

Frequently Asked Questions

How long should I expect my water heater to last?

Traditional tank water heaters in Hillsborough Township generally last between 8 and 12 years with proper care. The mineral content in your water supply, how heavily your household uses hot water, and keeping up with yearly maintenance all affect how long your unit will run. Regular professional service helps your system reach its full potential lifespan and prevents unexpected breakdowns.

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

Your household’s hot water needs determine the right tank size for your Hillsborough Township home. A family of four typically needs a 50-gallon unit, while larger households or homes with multiple bathrooms often require 60 to 80 gallons. Peak usage patterns matter too. Everyone showers in the morning or you run the dishwasher and washing machine simultaneously? You’ll need extra capacity to handle those demand spikes.

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

A typical water heater installation in Hillsborough Township takes between 3 to 5 hours from start to finish. The work involves disconnecting and removing your old unit, setting up the new system with proper connections to your plumbing and electrical or gas lines, then running tests to confirm everything operates safely. Factors like switching fuel types, upgrading venting, or working in tight spaces can add time to the job.

How often should I schedule water heater maintenance in Hillsborough Township?

Most water heaters in Hillsborough Township should get professional maintenance once a year. During that service visit, technicians flush out mineral buildup, test safety valves, and spot potential issues while they’re still minor and manageable. Regular yearly care keeps your system running reliably and helps you avoid the bigger, more expensive problems that develop when maintenance gets skipped.

What warning signs mean my water heater needs professional attention?

Several warning signs show your water heater needs professional help. Water temperature swings unpredictably. Hot water runs out faster than usual. You hear banging or popping noises from the tank. The water looks rusty or smells bad. You see pooling moisture around the base. These symptoms usually point to problems like sediment buildup, failing heating elements, or internal corrosion that get worse over time. Getting water heater repair in Hillsborough Township when you first notice these issues prevents more serious damage and keeps repair costs manageable.
