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!

Common Furnace Repairs We Handle in Princeton

Over time, even well-built furnaces require attention during NJ’s demanding winters.

Understanding both the problem and its underlying cause is how Princeton Air technicians approach every furnace repair in Princeton. You can be confident the solution addresses the root cause, not just the immediate symptom. Below are some of the most common furnace issues we diagnose and resolve for homeowners throughout Princeton every day.

A furnace that won’t start or begins running only to shut down moments later typically points to ignition system or pilot light trouble. Clicking sounds, delayed ignition, or cycling without steady heat production are common signs Princeton homeowners notice. Our Princeton Air technicians carefully inspect these components, determining whether wear, buildup, or electrical failure is the root cause. Proper ignition gets restored so your furnace starts smoothly and delivers reliable operation when you need it most.

Princeton homeowners notice their furnace cycling on but only cool air flowing through the vents. The heating system has lost its ability to generate warmth effectively. Common culprits include faulty ignition components, blocked airflow pathways, thermostat malfunctions, or failing internal parts that prevent proper heat exchange. Our experienced technicians diagnose the specific issue affecting your furnace repair in Princeton and restore dependable warmth to your home.

Strange sounds from your furnace often signal internal components beginning to fail, especially during Princeton’s cold snaps when systems work hardest. A rattling blower motor or grinding noise that seems minor today can escalate into costly damage if ignored through New Jersey’s demanding winter months. Princeton Air’s technicians quickly identify whether loose parts, worn bearings, or mechanical stress is causing the disturbance, then complete targeted furnace repair in Princeton that restores quiet, dependable operation before small problems become major breakdowns.

Princeton homeowners notice their heating bills climbing unexpectedly. This often signals a furnace struggling against New Jersey’s demanding winter conditions. Worn components, clogged filters, or declining system performance force your equipment to consume more energy while delivering less warmth. Our technicians identify what’s causing the inefficiency and provide targeted furnace repairs in Princeton that restore proper operation and reduce energy waste.

Princeton homes with uneven heating or temperatures that won’t match your thermostat setting often face thermostat calibration issues or communication breakdowns between the control and heating system. Older Princeton residences near the university area particularly struggle with this during New Jersey’s variable winter conditions. Thermostats may misread actual room temperatures or lose proper signal connection to the furnace. Our technicians in Princeton evaluate the entire control system and its wiring to restore precise temperature regulation throughout your home.

Short cycling in Princeton furnaces often occurs when heating systems work overtime against New Jersey’s fluctuating winter temperatures, causing the unit to start and stop repeatedly rather than running steady cycles. This pattern wastes energy and accelerates wear on critical components throughout your system. Princeton Air technicians pinpoint what’s driving the cycling behavior and deliver targeted furnace repair in Princeton, addressing everything from faulty thermostats to restricted airflow or aging internal parts.

Frequently Asked Questions

How do I know if I need furnace repair in Princeton?

Signs that point to furnace trouble in Princeton often start subtly. Rooms won’t warm up evenly, strange sounds when the system runs, or frequent cycling on and off. More obvious problems include a furnace that won’t start at all or can’t hold the temperature you’ve set on your thermostat. Having a Princeton Air technician evaluate your system gives you a clear picture of what’s wrong and whether repairs can restore dependable heating to your home.

How quickly can you respond to furnace repair calls?

We provide 24/7 emergency furnace repair in Princeton, NJ, and can often arrange same-day service when your heating fails unexpectedly. Our response times stay shorter because Princeton Air technicians are already stationed throughout Mercer County, not dispatched from distant locations. During heating emergencies, we prioritize urgent calls to get your warmth restored as quickly as possible.

Do you service all furnace brands?

Our technicians work on all major furnace brands and models you’ll find in Princeton homes, from decades-old units to today’s high-efficiency systems. This broad experience with different manufacturers means we can quickly identify what’s wrong with your specific equipment and know which repair methods work best for each type. Whether you have a gas, electric, or oil furnace, we’ve seen the common issues that affect each brand and understand how to fix them properly.

Should I repair or replace my furnace?

Your furnace’s age, the specific problem, and your repair history all play into this decision. A 10-year-old system with a minor issue usually makes sense to repair, while a 20-year-old furnace needing major work often points toward replacement. Princeton’s cold winters mean your heating system works hard, so we evaluate how much life your current equipment realistically has left. Our technicians explain what we find and give you straightforward guidance so you understand which path makes the most sense for your situation.

How can I reduce the risk of future breakdowns?

Regular maintenance is your best defense against surprise furnace breakdowns. During annual tune-ups, technicians clean components, check for wear, and test system performance to catch small issues before they become major problems. Princeton’s cold winters demand reliable heating, so many homeowners join maintenance programs like the Princeton Air Comfort Club to get scheduled service, priority response, and system monitoring that keeps their furnace running dependably when they need it most.
