We could not be more impressed โ€ฆ

Diagnosis of a leak, good service, honest and thorough! Excellent service person, Jonathan and Jesus.
Service personnel arrived as scheduled and preformed the maintenance as included in our contract without and question, problem or difficulties.
Jonathan did a great job servicing our AC, heater and water heater all during the same visit. Very knowledgeable and professional. Would highly recommend.
Dominic was prompt, efficient, and most importantly, very friendly. He showed me exactly what was wrong and explained why. The fix was just as quick. Thanks Dominic and Princeton Air!
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.
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 !!

Leak Detection and Pipe Leak Repair

Leaks can develop slowly over time or happen suddenly due to aging materials, corrosion, or pressure changes.

Professional leak detection and pipe leak repair services help identify the exact source of the issue and prevent further damage. Whether the leak is visible or hidden behind a wall, our team has the tools and training to find it and resolve it without unnecessary demolition to your home.

Modern leak detection methods use specialized equipment to locate moisture behind walls, under flooring, or beneath foundations. This technology helps pinpoint the problem without unnecessary damage to your home.

Many leaks can now be identified without extensive demolition. Acoustic sensors and pressure testing help professionals narrow down the affected area. This approach reduces guesswork and helps preserve surrounding materials.

A sudden spike in your monthly water bill may indicate a hidden leak. Even small, steady drips can waste significant amounts of water over time. Investigating the cause early can prevent larger plumbing issues.

Stains on ceilings, bubbling paint, warped flooring, or persistent musty smells can signal an active leak. These signs often indicate moisture buildup behind surfaces. Prompt attention helps prevent mold growth and structural damage.

Once the leak is located, our licensed plumbers repair the affected section with attention to the underlying cause, not just the symptom. Depending on the pipe material and the severity of the leak, that might mean replacing a fitting, repairing a joint, or swapping a compromised section entirely to prevent a recurrence.

Pipe Replacement

Over time, pipes naturally wear down due to age, corrosion, and mineral buildup.

When repairs become frequent or performance declines, replacement may be the more practical long-term solution. Upgrading older pipes can improve water flow and reduce the risk of ongoing leaks. Below are common signs that may indicate it’s time to consider pipe replacement.

If leaks continue to appear in different areas of your home, it may signal widespread pipe deterioration. Repeated repairs can become costly and disruptive. Replacement may provide a more reliable solution.

Brown or reddish water can indicate corrosion inside older pipes. This not only affects water quality but may also weaken the piping material. Replacing aging pipes can restore clearer water flow.

Mineral buildup or internal corrosion can restrict water flow over time. If multiple fixtures experience low pressure, aging pipes may be the cause. Replacement can help restore consistent performance.

Older homes may still contain galvanized steel or other outdated materials. These systems are more prone to corrosion and leaks. Modern piping materials offer improved durability and longevity.

Not every situation calls for replacing an entire pipe run. When damage or wear is confined to one section, our plumbers can replace that section cleanly, preserving the surrounding system while addressing the specific problem. This targeted approach is often the right answer when the broader system is still sound.

Pipe Retrofitting

Pipe retrofitting updates sections of an existing plumbing system to improve reliability and efficiency.

Rather than replacing the entire system, retrofitting targets specific problem areas. This approach can enhance performance while minimizing disruption. The following benefits highlight why retrofitting can be a practical upgrade for many homes.

Upgraded pipe sections can help reduce leaks and improve overall flow. Efficient plumbing systems waste less water over time. Retrofitting supports better resource management.

Replacing worn sections helps relieve strain on the rest of the plumbing network. Addressing weak points early can prevent more widespread damage. This proactive approach helps extend system longevity.

Retrofitting can strengthen vulnerable areas that are prone to corrosion or cracking. Reinforcing these sections lowers the chance of unexpected failures. Preventive updates can provide greater confidence in your plumbing system.

Modern materials and updated configurations can improve water delivery throughout the home. Retrofitting may also address layout inefficiencies in older plumbing systems. These upgrades support smoother day-to-day operation.

Many older homes develop pressure problems as pipes narrow internally or as new fixtures are added without balancing the overall system. Retrofitting with pressure regulators and properly sized supply lines restores even flow throughout the home and protects newer fixtures from excessive pressure.


Whole-Home Repiping

Whole-home repiping involves replacing all major water supply lines within a house.

This comprehensive solution is often recommended for aging plumbing systems experiencing widespread issues. A full repipe is a significant project, and our licensed plumbers plan it carefully to minimize disruption to your home while delivering a system built to perform for decades. Below are common signs that may indicate your home could benefit from a full repiping project.

If leaks continue to appear in different rooms or levels of your home, it may signal system-wide pipe deterioration. Constant repairs can become expensive and disruptive. Repiping addresses the root cause rather than fixing isolated sections.

Brown, yellow, or rusty-looking water often points to internal corrosion within older pipes. This can affect water quality and stain fixtures or laundry. A full repipe removes compromised materials and restores cleaner water flow.

When multiple fixtures experience weak flow at the same time, aging or corroded pipes may be restricting water movement. Over time, mineral buildup and internal scaling narrow pipe diameter. Repiping helps restore consistent pressure throughout the home.

Homes with galvanized steel or other aging piping materials are more prone to corrosion and leaks. As these materials deteriorate, reliability decreases and the risk of water damage increases. Replacing outdated piping with modern materials improves durability and long-term performance.

Today’s repiping projects typically use PEX, copper, or CPVC depending on the application and local code requirements. Our plumbers walk you through the differences, explain which materials suit your home’s specific conditions, and select the option that delivers the best long-term value for your situation.

FAQs About Pipe Services

How do I know if I have a hidden leak?

Unexpected increases in your water bill, damp spots on walls or ceilings, peeling paint, or musty odors can all signal a hidden leak. You may also notice reduced water pressure or the sound of running water when fixtures are turned off.

When should I replace my old pipes?

Frequent leaks, visible corrosion, discolored water, or reduced water flow are common signs that pipes may need replacement. Older materials such as galvanized steel are more prone to deterioration and may benefit from an upgrade to modern piping.

What is pipe retrofitting and why is it important?

Pipe retrofitting involves updating portions of an existing plumbing system to improve performance and meet current standards. It can help prevent leaks, improve water efficiency, and extend the lifespan of your plumbing without requiring a full system replacement.

How long does a whole-home repipe take?

The timeline for a whole-home repipe depends on the size of the home, accessibility of pipes, and the materials being installed. Most projects take anywhere from a few days to about a week to complete.

Do you offer emergency pipe services?

Yes. Princeton Air offers emergency pipe services to address urgent issues such as burst pipes, severe leaks, or sudden loss of water. Prompt attention to these problems is important to limit water damage and restore safe operation as quickly as possible.
