Barbara McQueary
Brandon arrived on time was very knowledgeable and insured everything was working properly with both my air conditioner and heating unit. He showed me pictures where he saw problems and discussed them with me. I feel Brandon is an excellent technician and would most definitely recommend him to others. He was very thorough in checking both units. Thank you Brandon, I appreciate you.

Electrical switches replaced and Outlet up-graded to code.

Newest work was on our old fashioned fluorescent ceiling fixture.
First off, the mechanic arrived at the promised time, so a couple of stars just for that!
John O. Quickly figured out the problem, had the replacement part in the truck and was finished all within an hour.
Great service, on time, professional manner….highly recommended!

New work 3/11/26: Smoke/CO2 detector went off for about 30 seconds at 11pm.
Nothing was running, no one cooking. The next morning we called for an appointment for the following day. Tech arrived on time and after explaining the event he agreed the detector was defective and replaced it free of charge due to it being within the warranty period. Another 5star rating for Princeton Air.

I have used Princeton Air for my A/C maintenance since I moved here. They are very professional. The technicians are very good. The company supports their technicians with the latest technology, which I like to see.
Douglas Smith
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.

I couldn’t be happier with Princeton Heating & Air Conditioning. From the start Christian — our original rep — was especially excellent: straightforward, honest, and absolutely no pressure or sales tactics, which really meant a lot to me (and probably the reason I felt comfortable moving forward with a complete overhaul).

After only a day from first meeting with Christian, the installation team spent a full 12-hour day installing two HVAC units (one up in the attic) and were professional, hardworking, and respectful the whole time. They took care to lay down cloth where they walked, paid attention to aesthetics so the finished work looks great, and even brought in electricians to install the additional outlets needed for a safe, code-compliant setup.

Clean, efficient, and trustworthy — highly recommend this company.

Plumber was very professional and clearly explained all issues. Work was completed quickly with no issues. Also provided a quote for a more extensive repair of different piping.
Henry Dombrowski
Had eight smoke/carbo monoxide detectors installed by Joe Leo. He was very thorough in explaining everything that was done. Also very friendly and knowledgeable about the service he was providing.
I was very pleased with his work.
Ruben Mckay
Princeton air and their service rep Jermaine came same day to fix a leak I had in one of my closets Jermaine found the leak told me what needed to be done gave me the pricing and scheduled me immediately for the next day. He fixed the leak addressed any issues or questions I had and I’m very pleased with the job thank you to him and Princeton air
Enrica Chretien
The technician assigned to us did a thorough job and his cheerful personality was the one bright spot in this whole mess for us.
Val Tellado
Erim and David did a phenomenal job. They were extremely careful removing the old water heater and bringing in the new one. We have a house with narrow staircases and doorways, along with tight turns. It was not an easy task, but they pulled it off without a hitch. Erim completed the installation and was extremely knowledgeable and professional.
