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! 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!

Frequently Asked Questions

How do I know if my furnace needs repair in Monroe Township?

Your furnace typically signals trouble before it fails completely through warning signs like strange sounds, rooms that won’t heat evenly, or frequent cycling on and off. Cool air from your vents or a system that can’t keep your Monroe Township home at the set temperature are clear indicators something needs attention. Getting furnace repair in Monroe Township during these early symptoms usually prevents bigger breakdowns. New Jersey’s coldest weather is coming.

Should I repair or replace my furnace in Monroe Township?

Several factors help determine whether repair or replacement makes more sense for your Monroe Township furnace. A single repair on a newer system often restores years of reliable heating. Older units with frequent breakdowns typically benefit more from replacement. The frequency of recent repairs and your furnace’s age are the biggest indicators. Systems over 15 years old that need multiple fixes within a year usually signal it’s time for a new unit.

How quickly can furnace problems be diagnosed in Monroe Township?

A skilled technician can typically identify what’s wrong with your furnace during one visit to your Monroe Township home. The diagnostic process involves testing key components like the ignition system, checking airflow patterns, verifying thermostat function, and inspecting safety mechanisms. After pinpointing the problem, we walk you through what we found. Then we discuss the repair options that make sense for your situation.

What causes a furnace to stop working during winter in Monroe Township?

Winter weather pushes furnaces to work harder, often revealing problems that weren’t obvious during milder months. The most frequent culprits are dirty air filters blocking proper airflow, ignition system malfunctions, faulty thermostats, aging internal parts, or electrical connections that have loosened over time. Scheduling annual furnace maintenance in Monroe Township before the heating season starts catches most of these issues. Small problems stay small. They don’t become midnight emergencies.

Is it safe to run a furnace that’s making unusual noises?

Strange noises from your furnace are warning signs that internal components need attention, even if the system continues heating your Monroe Township home. Banging, rattling, or squealing sounds often point to loose parts, worn belts, or airflow problems that will worsen if left alone. Getting furnace repair in Monroe Township right away prevents minor issues from turning into major breakdowns. New Jersey’s coldest months are tough enough.
