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 furnace breakdown when winter temperatures in Morristown have already plunged and your home is left 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. Morristown homeowners recognize when replacement makes more sense than another service call through these key indicators.

A single repair call is perfectly normal. A second one in the same heating season? That’s your warning sign. Morristown homeowners who find themselves calling for furnace service every winter are usually better served by replacement than continuing to patch an aging system.

Furnaces are designed for longevity, but they don’t run indefinitely. Your system has likely reached the point where operating costs exceed what a new furnace would cost to run once it hits that 15-to-20-year threshold. For Morristown homeowners, the financial equation shifts rapidly toward replacement at this stage.

Some rooms in your Morristown home stay cold while others feel comfortable? Your furnace has likely lost its ability to distribute heat evenly throughout the space. Those persistent cold pockets disappear for good with a properly sized new system.

Efficiency loss happens gradually with older furnaces throughout Morristown. Your utility bills often reveal the decline before you notice other symptoms. The same amount of heat gets produced for measurably less fuel when you install a high-efficiency replacement system.

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 stop working completely, older furnaces lose their ability to distribute heat evenly throughout your Morristown home. That one room nobody wants to sit in during January? Those cold bedrooms and drafty hallways are often symptoms of a struggling system rather than a layout problem with your home. Balanced, consistent warmth from room to room gets restored with a properly sized new furnace. You’ll experience the kind of comfort you might not have felt in years.

That nagging worry about whether your aging furnace will make it through another New Jersey winter creates stress for homeowners. Will this be the season it finally fails? Princeton Air’s new systems eliminate that uncertainty completely. You get a furnace you can trust when Morristown’s coldest days arrive.

Constant banging, rattling, or cycling on and off signals that your furnace is struggling to keep up with Morristown’s heating demands. Homeowners who’ve lived with the noise for years are often amazed by how quietly new systems operate. The warmth arrives without the racket. You’ll feel the comfort, not hear the equipment working.

Today’s high-efficiency furnaces pull significantly more heat from the same fuel compared to systems even a decade old. Across an entire heating season in Morristown, that efficiency gap compounds quickly. Homeowners who replace aging equipment routinely see meaningful drops in their monthly utility bills. Those 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 Morristown gets finished within one day, from equipment delivery through final testing and site cleanup. The job timeline runs from when we bring your new system to your door until we complete all testing and leave your home clean. Any ductwork changes that might extend the schedule get identified during our initial assessment. You’ll know the complete timeline before we start the work.

Can replacing my furnace actually lower my heating bills in Morristown?

Absolutely, particularly if you’re replacing a furnace that’s 10-15 years old or older. Today’s high-efficiency models pull much more heat from each unit of fuel compared to what was available even a decade ago. Homeowners throughout Morristown who upgrade from aging systems typically notice meaningful reductions in their monthly heating bills. Those savings add up significantly over the years.

How do you determine what size furnace my Morristown home needs?

We calculate the exact heating load your Morristown home requires rather than simply matching your existing unit’s capacity. Our technicians measure square footage, evaluate insulation levels, assess your home’s layout and ductwork condition, plus account for windows, ceiling height, and other factors that affect heat loss. A furnace that’s too large cycles on and off constantly. An undersized unit runs continuously without reaching your target temperature. Both scenarios waste energy and create comfort problems.

Does Princeton Air offer financing for furnace replacement?

Yes, we work with several financing programs that help Morristown homeowners spread the cost of furnace replacement over manageable monthly payments. These options include local utility rebate programs and flexible payment plans designed to fit different budget situations. Our team can walk you through what’s available when we visit your home for the initial assessment.

Who handles the permits for furnace replacement in Morristown?

Princeton Air handles all permit paperwork and inspection scheduling for your furnace replacement in Morristown, NJ. We pull the required permits through Morris County and coordinate with local inspectors to meet all New Jersey code requirements. You won’t need to visit any offices or make calls to government agencies. Our team manages the entire process from start to finish.
