Fast in resolve the problem . Very good work.

Maurice from Princeton Air was very professional and thorough. He explained what he was going to do beforehand. After my A/C inspection he described in detail what he had found and recommendations for attention. No hard sell at all. I received a detailed email summarizing his findings and recommendations with pricing within 30 minutes.

The visit logistics were perfect. I was given a time window. On the day I got texts and a phone call. The prices are very fair.

All in all a very professional service. I’ll use them again

Thanks Maurice

Edward Stelmakh
Excellent quality of service and very professional staff! You get what you pay for.
Fran Neville
The service i reveived was excellent! Princeton Air quickly gave me an appointment, then followed up with texts right to the time tje technician came to my door. The process was seemless and communication clear and service complete! BUT, best of all, the diagnosis was right on, the air conditioner repaired, and the cost was very reasonable! Call them if you need a repair!
Mike Smith
Tech (Alex) was on time, courteous, very professional. He let me know that, because of my contract w/McCallister, I would have no extra payment for the part needed.

Very professional and timely service
Sherrill Cohen
Thomas Ciaccia was the representative from Princeton Air who came to my house to diagnose the cause of non-functioning air conditioning. He provided excellent service that included testing two AC units, explaining how to use relatively new thermostats to best coordinate with the AC, presenting alternative ways of addressing the AC problems, and answering my many questions. I learned a great deal from his visit. It was well worth the reasonable cost.
Jerry Muntz
Wilver was great. Knowledgeable, polite and efficient.
