“Jimmy and Kionah were absolute professionals! Timely, well mannered, thorough with all tasks! They installed all parts of the system with skill and focus, while answering any questions we had. K actually swept my stairs after they were done. I had plumbers the day before, trust me they did NOT do that. I was cleaning for an hour after they left. But Jimmy and K, they left my house as clean as they found it and at a perfect”

“Wow! Just wow! Amazing Technician Melvin! He is an asset to this company. I did not like the last service that I received prior, and I was never going to call Princeton Air again. However, a neighbor stated that they recently did a revamping of their employees and that the company was better. So I gave it a shot since they put a coupon in the mail. Melvin came out and he was so efficient. So kind, so caring so knowledgeable that I felt that I was in excellent hands. He gave my air conditioner/heater a spring tune up and I can’t thank him enough for his professionalism and his great attitude and knowledge. Every employee should be like Melvin. He truly restored my faith in this company and I now will continue to recommend Princeton Air to family and friends.”
