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.

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

Our Princeton Plumbing Services

Your plumbing system is made up of many connected parts, all working together to support your home.

Princeton Air provides a full range of plumbing services in Princeton, handling everything from targeted repairs to larger system improvements with a focus on reliability and consistency. We approach every job with a focus on accuracy, durability, and consistent performance.

Emergency Plumbing

Some plumbing problems need immediate attention to prevent further damage.

A burst pipe, major leak, or sudden water loss can escalate rapidly without proper help. Throughout Princeton, Princeton Air delivers responsive emergency plumbing service. Our approach focuses on containing the issue, limiting damage, and restoring basic function while we identify the root cause and correct it properly.

broken pipe icon

Pipe Services

Pipe services cover everything from targeted leak repairs to full replacements and repiping.

From minor leaks to extensive system problems, Princeton Air pinpoints the root cause and performs the necessary work to restore proper flow, pressure, and lasting performance. Our pipe repairs, replacements, and upgrades in Princeton maintain reliable plumbing system operation.

  • Pipe Leak Repair: A leaking pipe can cause damage quickly if left unaddressed. It might be hidden behind a wall, running beneath a floor, or visible along an exposed section. We locate the source of the leak accurately and complete pipe repairs in Princeton that restore a secure, watertight connection. Our approach minimizes unnecessary disruption to your home’s structure or finishes while addressing the problem completely.
  • Pipe Replacement: As piping materials deteriorate over time, individual repairs often can’t restore the reliable performance your Princeton home needs. Damaged or aging sections need replacement with updated materials that meet current standards. Our replacement work focuses on proper routing and secure connections. This delivers the long-term durability that keeps your plumbing system functioning dependably for years ahead.
  • Frozen Pipes: Cold weather can cause pipes to freeze rapidly. These frozen sections frequently crack or burst when temperatures begin to thaw. Princeton Air safely thaws affected areas, examines surrounding piping for stress or damage, then reinforces vulnerable sections as needed. This process restores water flow while helping minimize the likelihood of recurring freeze damage in Princeton homes.
  • Pipe Leak Repair: Hidden leaks in Princeton homes often surface far from their actual source. Water follows pipes and structural elements before becoming visible. This makes precise detection critical for effective repairs. Princeton Air tracks down the true origin of the leak, then repairs or replaces the damaged section while securing all connections to prevent additional damage behind walls or beneath floors.
  • Pipe Retrofitting: Many Princeton homes feature plumbing systems designed for different usage patterns than today’s households demand. Through retrofitting, we can improve flow rates and balance pressure while addressing layout constraints. All without complete system reconstruction. Existing piping gets adjusted and upgraded to better match your current household needs and daily routines.
  • Whole-Home Repiping: Repiping in Princeton offers a long-term solution. This works when pipes throughout the home have become worn, corroded, or unreliable. The project gets planned to minimize disruption while we replace outdated materials with modern piping and properly configure the entire system for consistent pressure and flow.

Drain Cleaning

Drain issues often start small but tend to worsen over time if not addressed properly.

Buildup within the system typically causes slow drains, recurring clogs, and standing water in Princeton homes. Using professional-grade equipment, Princeton Air removes obstructions thoroughly and restores proper flow. This helps reduce the likelihood of repeat issues.

  • Hydro Jetting: Persistent buildup requires stronger action. Hydro jetting clears grease, debris, and scale from inside pipes using high-pressure water. Beyond removing blockages, this process also improves the overall condition of the line.
Wrench and pipewrench icon

Sewer

Sewer line problems can affect your entire home and need immediate attention to limit widespread issues.

Backups, foul odors, or slow drainage often signal deeper problems within the sewer system. Princeton Air delivers complete sewer services in Princeton, NJ. Our accurate diagnostics and solutions address immediate concerns while supporting long-term reliability.

  • Camera Sewer Inspections: Fixing sewer line problems correctly starts with understanding what’s happening inside the pipe. Using camera inspection equipment, Princeton Air views the interior of sewer lines in Princeton in real time. We locate blockages, cracks, root intrusion, or buildup. This process eliminates guesswork and provides a clear basis for recommending the right solution.
  • Sewer Cleaning: Buildup, debris, and minor obstructions get cleared away through regular sewer line cleaning before they turn into serious blockages. Princeton homeowners can maintain reliable flow and reduce backup risks that disrupt daily routines and damage property. Princeton Air’s sewer cleaning services in Princeton make this possible.
  • Sewer Inspection: Through a complete sewer inspection in Princeton, we evaluate the line’s overall condition and structural integrity. Signs of wear and developing problem areas get assessed thoroughly. This gives you clear insight into your system’s current performance and identifies what may need attention down the road.
  • Sewer Line Repair: Cracks, separations, or root infiltration in Princeton sewer lines need immediate, targeted repair to prevent further damage. Our team accurately diagnoses the extent and location of sewer line damage. Then we complete repairs using appropriate methods that minimize disruption to your property and restore reliable, code-compliant flow throughout your system.
  • Sewer Line Replacement: Princeton Air handles complete sewer line replacement in Princeton with thorough planning that minimizes disruption to your property. After evaluating the line’s condition and coordinating required permits, we complete the installation to current code standards. This approach delivers long-term, dependable performance for your Princeton home’s sewer system.
  • Trenchless Pipe Lining:Excavation needs to be kept to a minimum sometimes. Trenchless pipe lining in Princeton offers a solution that restores damaged sewer lines from the inside out. A new interior lining gets created within the existing pipe, sealing cracks and improving flow while your landscaping, driveway, and other hard surfaces remain undisturbed.

This allows your tankless unit to provide dependable hot water service to every fixture in your home.
  • Tankless Water Heater Maintenance: Regular maintenance keeps tankless systems operating efficiently over time.

Princeton Air performs descaling, inspects internal components, and verifies system settings to maintain consistent hot water production. This prevents added strain on your unit.
  • Tankless Water Heater Repair: Error codes, inconsistent temperatures, or complete loss of hot water from your tankless unit in Princeton typically signal problems with internal components or restricted flow paths.

A properly functioning ejector pump keeps below-grade plumbing operating safely and reliably.

Moving wastewater upward to reach the sewer line requires a system that operates consistently without fail.

Expansion Tanks

Without a way to manage pressure from water heating, it can build up over time and place stress on pipes, valves, and fixtures throughout your home.

Excess pressure gets absorbed by an expansion tank, which protects your system from unnecessary wear and potential damage. To help stabilize pressure and extend your plumbing system’s life, Princeton Air installs and services expansion tanks in Princeton. An undersized or failing tank won’t provide the protection your system needs. Proper sizing and placement matter. The right setup keeps pressure within a safe range while reducing strain throughout the entire system.

Water Treatment

The quality of your water impacts your plumbing system, appliances, and daily use.

Water quality issues like minerals, contaminants, and chemical imbalances gradually create buildup inside your pipes while reducing efficiency and accelerating fixture wear. Through water treatment solutions in Princeton, Princeton Air addresses these problems at their source. This approach protects your plumbing system and delivers more consistent, reliable water for daily use throughout your home.

  • Water Conditioners: Water quality issues including hard water, sediment, chlorine, and various contaminants impact both the taste and safety of your water supply while causing accelerated wear throughout your plumbing system and appliances. Throughout Princeton, Princeton Air matches water conditioning systems to your home’s unique water conditions, tackling quality concerns that extend well beyond mineral hardness.

  • Water Testing: Understanding exactly what’s in your Princeton water supply allows the right treatment solution to be recommended with confidence.

Frequently Asked Questions

How Do I Know if a Plumbing Issue Is Serious or Something I Can Wait On?

Persistent leaks, multiple slow drains, or declining water pressure typically signal underlying problems that won’t fix themselves. What starts as a small issue often grows into expensive damage when left unaddressed. In Princeton homes, these warning signs usually indicate deeper system problems that require professional plumbing repair in Princeton. Don’t wait. Prevent costly failures down the road.

What Are the Most Common Plumbing Problems in Princeton Homes?

Aging supply lines, mineral deposits from hard water, and accumulated debris in drains represent the most frequent plumbing challenges throughout Princeton. Winter freezing and spring thaw cycles can stress pipes, while areas like Tree Streets and Riverside often deal with sump pump issues during heavy rainfall periods. Catching these problems early prevents them from developing into major system failures that disrupt your entire home.

Is It Better to Repair or Replace Plumbing Components?

Component age and overall condition drive this decision more than anything else. Dealing with one specific problem on newer equipment? Repair usually makes sense. But multiple failures or aging components throughout your Princeton plumbing system often point toward replacement as the smarter choice. Looking at how the entire system is performing gives you a clearer picture of what you’re really facing.

How Often Should I Schedule a Plumbing Inspection?

Most Princeton homes should have a plumbing inspection every one to two years to spot developing problems before they turn into major issues. This timing works well for catching mineral buildup, small leaks, or component wear that isn’t obvious during daily use. Got older pipes? Dealt with repeated plumbing problems? Annual inspections help stay ahead of system failures that could leave you without water or cause property damage.

Why Do My Drains Keep Getting Clogged?

Drains that keep backing up usually mean you’re dealing with accumulated material deep inside the pipes, not just something stuck near the surface. Hair, grease, soap scum, and other debris gradually coat the interior walls and narrow the passage over time. Professional drain cleaning in Princeton removes this buildup from the entire line. This stops the cycle of repeated blockages that partial clearing can’t fix.
