Local Electricians Who Know What’s Behind Your Walls

Homes across Hamilton Township each carry their own story and their own electrical history.

Hamilton Township homes span decades — established neighborhoods around Hamilton Square, older homes near Yardville, newer construction closer to White Horse and Nottingham. We’ve worked inside enough of them to know what each era tends to hide and what it takes to bring those systems up to where they need to be. That familiarity shapes how we diagnose, what we recommend, and how we approach every job.

I highly recommend Ryan Gobel, technician, of Princeton Air. He did a diagnosis of my boiler's problem and explained calmly the problem. I brought Princeton Air in for a second opinion after a "senior tech" at AJ Perri fast talked me and told me some lie about what was wrong. I canceled them. Got Princeton Air. Ryan came out and said something different and fixed the boiler correctly. He is professional, extremely knowledgeable, and nice. Thank you Ryan and I look forward to seeing you again for the fall maintenance.
I needed a new HVAC system. From the beginning of the process through the finished installation the McAllister Service Co team was very professional and answered all my questions to my satisfaction. The installation went smoothly and the team did a thorough clean up of the equipment installation locations. I want to say a special thanks to Zeus and Michael D my maintenance reps, Jason L my system and installation project manager, and Joe D, my installation team manager and his team on 6/8.
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. They were very competitive on price and did an excellent job installing the unit. I am planning on having them provide all maintenance on the unit. I highly recommend Princeton Air Conditioning.

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! It’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 I’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 I’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 wasn’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.

Frequently Asked Questions

How do I know if my electrical panel needs to be replaced?

If your breakers trip frequently, lights dim when appliances run, or your panel feels warm or makes unusual sounds, it may no longer be safely handling your home’s electrical demand. Many older panels were not designed for today’s technology, appliances, or EV chargers. A professional evaluation from Princeton Air can determine whether a targeted repair or a full upgrade is the safer long-term solution.

Do I need a permit for electrical work in Hamilton Township?

Most panel upgrades, generator installations, and significant wiring changes require permits and inspections. Princeton Air handles the permitting process and ensures all work complies with New Jersey code requirements, giving you confidence that the job is completed properly and documented appropriately.

Is whole-home surge protection really necessary?

Power surges are more common than many homeowners realize and can originate from storms, grid switching, or large appliances cycling on and off. Whole home surge protection adds a layer of defense at your electrical panel, helping protect sensitive electronics, appliances, and your overall wiring system from costly damage.

Can you upgrade wiring in an older home without major disruption?

In many cases, yes. While some access is necessary, experienced electricians can often complete rewiring projects strategically to minimize wall and ceiling impact. We plan carefully, communicate clearly about what to expect, and treat your home with respect throughout the process.

What size generator does my home need?

Generator sizing depends on how much of your home you want powered during an outage and the electrical load of essential systems. We perform a detailed assessment of your household’s usage and recommend a solution that balances protection, efficiency, and long-term reliability.
