  • Quality workmanship and premier customer service are hallmarks of Princeton Air in NJ. In the last 12 months I replaced two Lennox central air conditioners with new Lennox units and due to Hurricane Irene a new Lennox furnace. I have spent over 20K with Princeton Air in the last 12 mos.

  • I want to let you know that I had a chance to inspect the work you guys did for Pat Palmer and Mark Widmer. When I replaced a bathroom fan for them, I had to remove some drywall from their bathroom ceiling where Princeton Air had installed dense pack cellulose a few years ago.

  • The house is performing wonderfully. The gas usage for November and December was 247 therms. The gas usage for last December alone was 248 therms.

  • Princeton Air personnel provided us with an energy efficient heating/air conditioning system that worked without current heating challenges. We were very happy with the service.

  • Princeton Air and Eric saved us from another cold night. You were there when PSE&G was not. Thank you.

  • Technician was cordial, polite, & professional.

  • I just wanted to say how impressed and extremely happy I was with Princeton Air. The professionalism, courtesy, and the attention to detail of Matt, Jimmy, Nelson, and Wes was both refreshing and much appreciated.

  • Returned home at 5:00PM last evening after being away for 2 plus weeks to find the furnace completely shut down...no heat, 48 degree temp in the house. Asked if someone could get there that evening and was advised that Eric, a Service Tech, was on a call and he would get back to us.... Read More

  • We experienced a warranty issue that caused my ceiling to become water damaged, Sean's ability to stay calm helped me to calm down as well. I think it was his polite demeanor that caused me to remain a customer of your Company.

  • Thanks for the info, and thanks for bringing the job to completion. Marty and Marcel took care of business, and were happy campers. It was too cold (below 45 F) for the heat pump to fire, but I'll wait for a warmer day and keep an eye on it. The 7 inc.

  • The professionalism and expertise that I encountered from Kevin made me fully satisfied with this past Saturday's scheduled service. He explained in detail how my system works, he also pointed out the root cause of a problem I had been having and corrected it.

  • This letter is commending Sean. Yesterday, he came to check the furnace at my home. He is efficient and his explanations are clear. He remembers where everything is, and I absolutely trust his work. Its very nice to know that I can rely on Sean. I really appreciate his work.

  • I just wanted to call to comment on Brennens performance. He came out to service my unit. Brennen was very professional and very knowledgeable. Thank you.

  • I just wanted to call in to say what a wonderful job Nick did over the weekend. I was amazed by the amount of time that he spent in the heat and humidity to get the unit running. I am thankful to Nick and the entire company that I had A/C over the weekend

  • Part of the reason why I stick with your company is because of Sean. He takes time to explain things to me and he helped me decide which new system to get last year. He is a real asset.

  • You guys were the first company to figure out how to replace the units here at Governors Lane as built. Congratulations. Chris et al. were great to work with. Thank you.

  • Eric handled himself very professionally and took the time to listen to me. Because of his sincere interest, will be preparing a proposal to substantially upgrade our system. He seems to know his profession well and handled me in the right manner.

  • I just wanted you to know that Rich is a very pleasant, professional and courteous person. All of your employees that have come here are the same. You guys must be doing something right.

  • Brennan performed the seasonal service on our A/C unit. We were very impressed. He took care of everything very efficiently and completely. He also quickly solved a potential problem. This is to commend Brennan for his fine work and his excellent customer service.

  • You have some great people working there. They are fantastic especially Jack and Eric.

  • On February 26, 2007 I experienced the frightening experience of having my gas carbon monoxide detector go off. I cannot say enough to the diligence and professional manner Eric demonstrated while trouble shooting.

  • Your guys have always been good, but these two men (Geoff and Rich) were the most polite, professional, and personable I've had. They represent your company very well.

  • Wanted to let you know that Eric performed yet another excellent maintenance on my contract. He has an excellent positive attitude coupled to a get it done right work ethic. It is a pleasure to have him here to take care of things.

  • I am writing this letter to you to thank one of your employees. Paul noted a pin-hole leak on the side of the main water line that enters the building switchgear room.

  • We returned home from a one week vacation to Aruba, at about 10:30 pm, to a 50 degree home. We had no heat. We called Princeton Air and the Service Rep was at our home within 25 minutes. Sean fixed the problem quickly. That is great service. You guys are the best.

  • The technician (Kevin) was wonderfully polite and respectful of my home. He was very professional, patient, thorough, and showed a genuine concern for the well-being of my family

  • Jack was my service technician. He explained everything to me, tolerated my constant presence while he worked (I know how annoying that can be) and did a superb job. He didn't try to scare me into a new system, even though this one is getting old.
