Heating Installation & Repair Services in New Jersey

On 04/01/2026 A 3-man Princeton Air crew installed a new Carrier central A/C unit at my house, and did a terrific job. They all deserve a 5-star rating. The new plenum housing the new evaporator coil has never been so securely attached to the furnace or so well insulated that there are no air leaks at all in the plenum itself and at the furnace-plenum junction. Everything is so quiet now I have sometimes have to go to the new thermostat to find out what's running when. Everything works perfectly.

Very Good and professional!!

Jorge was polite and very efficient. We felt confident in his assessment and service. He was knowledgeable and very neat

We recently had Princeton come out to do our air conditioning service. The technician was professional and pleasant and thorough. They followed up with a repair that was needed. I would recommend Princeton for any of my HVAC, plumbing or electrical needs..

Daniel was awesome, he was efficient and explained everything in detail with no added pressure to do any work.

Great work! From the initial inspection of my 27-year old furnace/AC (in the attic) by Cruz to the Home Advisor Andre who worked with me to get me the best value for what I needed, everything was clearly explained. On March 16, 2026 James the electrician and two installers (sorry I forgot their names) arrived and began the removal of the old system and the installation of the new one. I was very pleased with all the work that was done and am very happy with my new, more efficient system.
Great work guys. I highly recommend Princeton Air for anyone's heating and plumbing needs.

Great experience. Workers explained everything and completed the work.

Ryan : A very honest and competent technician 5 Star 🙏

Generator Issues

Jermaine arrived in a timely manner. He explained to me why a new water heater was needed. The job was done professionally. My home was cleaned up after the work was done.

Same day I had two maintenance issues that needed to be taken care of – plumbing and electrical. Both technicians were outstanding
G! Writing separate reviews for both!
GENERAL REVIEW FOR PRINCETON AIR – DO NOT SWAP TABLETS WITH PHONES TO CONFIRM AND SEE PRICING AND OPTIONS FOR CUSTOMERS. COMPARING PRICING AND OPTIONS IS EXTREMELY DIFFICULT ON THE PHONE. DO NOT PUT PROFITS AHEAD OF CUSTOMER EXPERIENCE. YOU WILL GO DOWN. PLUS MAKE YOUR PRICES REASONABLE. You have good workers. They will GO if we stop calling. Making hay while the sun shines will only work for so long! 5 ⭐️ is for the technicians and not the company who is clearly OVERPRICED!!!

Muhammed "MIKE" Gundogan from Princeton Air was exceptional and is a true professional. Someone who puts a customer’s experience far ahead of their own. Someone who understands that a job well done means repeat customers. Thank you so much!

Rob DeNizo and his assistant Jtrain were excellent and highly professional.

We had both our heating boiler and air conditioning system replaced over the past 2 days by Princeton Air (aka Weltman Home Services). The sales and contract process led by Chris M. was quick, thorough and easy to understand. The installation team was Christian J., Michael C. and Jimmy. Electrical work was done by Joseph L. The entire service team was friendly, professional, very knowledgable and efficient. Both system installations were done within 1 day as promised. We have been customers for 2 years and continue to always be extremely pleased with the team and their services.

Dom was great. He explained everything clearly, was friendly, and thorough. Would highly recommend him.

Quick, informative and professional!!! Excellent service all around.

Excellent service person!

Alberto repaired our heat pump. He was extremely friendly and professional.

My heat was not coming on and Daniel realized it was a safety setting that kept turning it off. He was extremely professional, kept me up to date on his discovery, cost and fixed it in a timely manner. I am very happy with Princeton Air. I have been a customer for several years.
