Total Home Comfort, Delivered with Precision

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.

Great job by Jorge!! Friendly, and answered all my questions.

He really take care of many problems at once. I sincerely appreciate for his job!!

Excellent, professional service. The technician was highly skilled and thorough.

The technician Jose Cologne came to service my havoc system. He was very knowledgeable, professional and honest. He was thorough in explaining each detail that needed to be done with the system and the importance of maintenance upkeep. Thank you Jose!

his attitude and explanation of his knoledge.

Excellent experienced
Person

Prompt, courteous, and thorough work on the tankless system.

Princeton Air responded quickly to a problem we had with our hearing. They sent out a technician who very quickly diagnosed the problem and fixed the issue. Ryan took his time to explain everything as well as a couple of additional possible future problems. On a second visit to finish up some outstanding things he noticed he was courteous and once again clearly explained what he was going and why. After the work was completed the total cost was 1/3 of a prior estimate I had received from another company. I would highly recommend Princeton Air and their technical Ryan.

Ryan did a great job coming out, assessing the issue and fixing it as an interim solution until we get a new heater. Highly recommend!

Had the heating system replaced by them. Did a great job. Came in time, finished in a reasonable time frame and left everything clean
