Ryan G. arrived to perform regular A/C maintenance and determined the drain pipes leading from the condensor coil into the sump were clogged and in need of replacement. He performed the work in timely fashion at a reasonable price and also took the time to provide some useful advice. This is the second time Ryan has performed service in my home and I find him to be a helpful and conscientious professional.
Technician Alberto Martino was excellent thorough and explained everything. Send him every time.

Johnnie from Princeton Air was here within timeframe noted and performed yearly maintenance and made suggestions regarding add ons we may want to consider. All maintenance work and cleanup were up to the standards advertised by Princeton Air.
I was very happy with Norman, I found him very accomidating, skilled and professional .
Joe was excellent! He came right on time and completed the job in a professional and competent manner. Will definitely have him come out for other projects! Steve came out to repair some plumbing issues. He was excellent. He explained what needed to be done and scheduled the work immediately. I would highly recommend Weltman Home Services. Ryan did a great job. I haven't had anything but excellent service from Weltman. Herb and Christian installed my new HVAC system. They were great! Very pleased with the entire Weltman team. Another 5 star job! Thank you! Henry installed a new attic fan. He did a great job! Michal and Eric came diagnosed and fixed the issue. Great service as always! Eric arrived right on time and completed all of the necessary work. Excellent work! Had outside water source replaced today (11-30-23) and Brent did a great job! I always rely on Weltman! Steve came out and cleaned my dryer vent. He was quick yet thorough. The cleaning was long overdue and my dryers effectiveness has been improved. Great service as always! Routine maintenance on the HVAC system by Michael and Andre. Excellent service as usual. New service on October 6, 2026. Joe and Stephon did a great job. My new light fixture looks great. They're always reliable and the service is excellent. Would strongly recommend!

Great service. Easy to schedule an appointment and the technicians are knowledgeable, punctual, and friendly. At our last system maintenance appointment, I pointed out a problem we were having to the technician, Stivan, and he immediately fixed it. He also identified some other issues and clearly explained/documented what the problem was and what needed to be done. Highly recommended! Update 10/2/26: I've used Princeton Air for many years for HVAC maintenance, but today was the first time I've used them to install a new system (heating and AC). The service was fantastic. Asterson and team arrived promptly and, once I'd shown them where everything was, they completed the installation without any further interruptions to my day. Just as they were packing up and getting ready to leave, Asterson even took the time to fix and completely unrelated problem I was having with one of my air vents. Very happy with my new HVAC system.

This approach lets us provide effective air conditioning repair in New Brunswick, NJ, regardless of whether you have Carrier, Trane, Lennox, or other manufacturer’s equipment.

What if my AC keeps breaking down in New Brunswick?

Repeated breakdowns usually point to a deeper problem with your system.

How can I prevent future AC problems in New Brunswick?
