On 05/17/2026 both Brian Hassan working on my backup generator and Cruise Rodriguez working on my central A/C system did excellent jobs inspecting, servicing and repairing my equipment. Cruise found coolant gas leakage problems with my A/C system and advised me the best and least expensive way to deal with them. I was highly impressed with their work and give them my highest rating.
Chris Petillo
Reliable service. Always feel better after they do their system checks.
Michael Giambra
I called them in the morning on a holiday and they were there by 12:30. Kelvin Garcia was very nice, polite, and figured out the problem in no time. He had the right part for my 100 year old Weil McClain gas Hot Water hear boiler. We had heat back in no time. I could not be more satisfied. Thanks Princeton Air!!! Michael Giambra, Rocky HIll, NJ

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 mannerโ€ฆ.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.
