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!

Replace Your Furnace Before It Leaves You in the Cold

Nobody wants to face a failing furnace after temperatures have already dropped and left their South Brunswick home without heat.

An aging system can only be carried so far by repairs. The time eventually arrives when you must decide whether the system remains worth fixing. South Brunswick homeowners can recognize when replacement makes more sense than scheduling another service call by watching for these key indicators.

A single repair call is perfectly normal. When you’re scheduling a second service visit in the same heating season, that’s your warning sign. South Brunswick homeowners dealing with a furnace that demands attention every winter are usually better served by replacement than by continuing the cycle of repairs.

Furnaces are built to last, but they don’t run indefinitely. After 15 to 20 years of heating your South Brunswick home, you’re probably investing more in repairs and higher energy costs than a new system would require to operate. The financial equation shifts rapidly toward replacement at that point.

When some rooms in your South Brunswick home stay cold while others feel comfortable, that’s usually a sign your furnace can no longer distribute heat evenly throughout the space. Those persistent cold pockets disappear permanently with a properly sized new system.

Efficiency drops slowly in aging South Brunswick furnaces. Your utility bills often reveal the problem before you feel it. High-efficiency replacement systems deliver identical heat while consuming significantly less fuel.

Keep Your New Furnace in Peak Condition

Most manufacturers require documented routine maintenance to keep warranty coverage intact. Comfort Club membership takes care of that automatically, so you’re never caught in a situation where a repair claim gets denied over a missed service visit.

Professional system checks before each heating season give members peace of mind throughout South Brunswick’s winter months. Early detection of small issues helps prevent emergency repairs while extending your furnace’s efficient operation. When you schedule your replacement, ask about enrollment options.

What a New Furnace Actually Does for Your Home

A furnace replacement changes the way your home feels, functions, and costs to run every single day.

Long before they completely fail, older furnaces start losing their ability to heat your home evenly. That one room nobody wants to use during South Brunswick’s coldest months? Cold bedrooms and drafty hallways usually signal a struggling system rather than a problem with your home’s layout. Balanced, consistent warmth from room to room returns when you install a properly sized new furnace. The kind of comfort you might not have felt in years.

Owning an unreliable furnace creates a particular kind of anxiety as New Jersey winter approaches. That nagging question of whether this will be the season it finally fails. Princeton Air eliminates that worry entirely with a new system. You’ll have a furnace you can count on completely when cold weather arrives in South Brunswick.

Constant banging, rattling, or cycling on and off signals that your furnace is struggling to keep up with South Brunswick’s heating demands. Homeowners who’ve lived with noisy systems for years are often amazed by how quietly modern equipment operates. The warmth arrives without the disruptive sounds. You’ll notice the comfort, not the mechanical noise.

Today’s high-efficiency furnaces pull dramatically more heat from each unit of fuel compared to systems that are just a decade old. Across South Brunswick’s entire winter heating season, that efficiency gap creates substantial differences in energy consumption. Homeowners throughout Middlesex County who replace older equipment consistently experience notable drops in their monthly utility costs. These savings accumulate year after year throughout the system’s lifespan.

Frequently Asked Questions

How quickly can Princeton Air replace my furnace?

A typical furnace installation in South Brunswick takes one full day from start to finish. We bring your new equipment, remove the old system, complete the installation, and handle all testing and cleanup in that single visit. Any additional work like ductwork changes gets discussed beforehand. You’ll know exactly what to expect and how long it will take.

Can replacing my furnace actually lower my heating bills in South Brunswick?

Absolutely, particularly when you’re replacing a system that’s 10+ years old. Today’s high-efficiency models pull much more heat from each unit of fuel compared to older furnaces. This translates to lower monthly bills throughout South Brunswick’s heating season. The energy savings add up year after year, making the efficiency difference especially noticeable for homeowners who’ve been running older equipment.

How do you determine what size furnace my South Brunswick home needs?

We calculate the exact heating capacity your home requires rather than simply matching your existing unit’s size. Our technicians measure square footage, assess insulation levels, and evaluate your home’s layout and ductwork condition. Plus other factors that affect heat loss in South Brunswick homes. Getting the size wrong creates comfort problems and higher energy bills, so we run the numbers to match your furnace perfectly to your space.

Does Princeton Air offer financing for furnace replacement?

Yes, we work with local utility programs to provide financing options that spread the cost of your new furnace over manageable monthly payments. These programs are specifically designed to help South Brunswick homeowners upgrade to more efficient heating systems without the upfront financial burden. Our team can walk you through what’s currently available when we visit your home for the initial assessment.

Who handles the permits for furnace replacement in South Brunswick?

Princeton Air handles all permit applications and inspection scheduling for your furnace replacement in South Brunswick, NJ. We pull the required permits, coordinate with local inspectors, and make sure everything meets New Jersey code requirements. The paperwork and scheduling stays off your plate completely.
