Steven Raffuel
A/C went down unexpectedly in the middle of humid New Jersey summer. Princeton Air was out in less than 24 hours and found the problem. Kudos to our tech, Ryan Gobel who must have logged a mile going between the condenser and the air handler in the attic! Not to mention the tight working area in the sweltering attic!
JRM
Daniel was great. He went above and beyond for me. I would definitely use them again and I can recommend
Janet Grisi
Joe was fantastic . Removed non working ceiling fan and installed the new one we purchased . Made sure all was safe, correct electrical format to meet codes, we were , instructed on how to use it and in various settings per the remote . Completely cleaned up , moved furniture back and hauled away the removed fan . All in all, as usual, 5 star service from Princeton Air .

Get a contract for service as well, saves you $$$ and you get priority service when you call.
John Adamovics
Quick diagnosis of AC👍
Ryan R
Latrell was excellent! Service and communication couldn’t be beat. I felt like I was in the loop about what needed repairing on my A/C throughout the process and left feeling more knowledgeable about how the whole system works. Thanks, Latrell!
Jennifer Micera
We are very happy with our sales representative Joseph who handled all our concerns in a professional & knowledgeable manner. The team of installers were punctual, professional and extremely courteous! Great job from start to finish.
thomas grisi
Another 5 star rated job well done by Princeton Air.
This time a ceiling fan replacement.
Joe L. came in, removed the old fan, assembled the new fan, cleaned up and without us touching anything.
Joe took the time to explain the multi-function remote operation all with a smile and friendly demeanor.
Ask for Joe L. For your next electrical job!
William Weinstein
The technician, William Delgado was prompt in arrival to perform annual furnace maintenance. He was polite, professional, knowledgeable and thorough in his work.
Munir Nassar
Neim Colaku was the Princeton Air technician who worked on our two AC units. He was excellent, very knowledgeable , very professional and a pleasure to work with. He inspected the two AC units and did fine tuning. He noticed that the two compressor units were not level- an excellent observation. He went beyond the call of duty, left to get rubber inserts to level the units. Came back with the rubber inserts and leveled the two units. I think his commitment to excellence in service, his keen observation skills and his dedication to do his best are very commendable qualities. If there is a rating more than 5, I will gladly select it. Thank you Neim and we are grateful for your excellent work.
Richard Weller
Tech from Princeton Air (Brian Hassan) showed up on time and performed yearly maintenance on our Kohler Generator. Very professional and courteous technician. Thanks for taking care of our generator like it was your own.

Just had a tech Cruise Rodriguez trouble shoot a minor wiring issue on our new Carrier furnace which was installed this week. As we were installing a new thermostat WiFi Honeywell there was a mismatch which Cruise located and rewired. System seems to be up and running with new thermostat.
Thank you Cruise for your expert help in resolving this issue.

Daniel came out for the regular maintenance of my AC system. He did a thorough job and took his time. He kept me posted along the way. He was professional and respectful. He made some recommendations for additional service based on his findings but he wasn’t pushy about them.

Thank you Daniel.

Princeton Air has been fabulous whenever we needed them. They have replaced our water heater and HVACover time. Service and work has been great and price has been very competitive. Will recommend them to everyone.

Just to let you know everything here is great now thanks to Latrell! What a wonderful young man. He not only helped me with our thermostat but he was so kind professional and friendly.
